Installing and Managing FS25 Mods on PC

By the end of this guide, you should be able to explain where your game is looking, what you installed, why it belongs there, and how to get back to a working setup. A mod sitting in a folder is only the beginning. The useful finish line is a mod that loads, works in a disposable test save and leaves your main farm recoverable.

This guide covers normal player installation on Windows PC. Console instructions, mod development and building a mod from source are different jobs. Storefronts and custom configurations can use different locations. Wherever your folders happen to live, confirm them before copying anything.

The numbered workflow below is the TW Farms method: change one thing, keep the previous working state and test a clear outcome. The read-only checks stated above are evidence about the inspected files, not a claim that every step has been gameplay-tested on every edition.

Protect your working farm

Before downloading a replacement or removing anything, decide which save you can afford to use as a test. If the answer is “none of them”, make the backup first.

1. Close FS25 completely. Do not replace files while the game or a dedicated server is using them.
2. Copy the relevant save folder out of the active user-data folder into a separate backup location. Preserve the whole folder, not just the XML file you think matters.
3. Preserve the current mod ZIPs and any mod settings your setup depends on. A save backup without the old mod versions may not recreate the old state.
4. Give the backup a date and a short purpose, such as “before production update”. Keep it outside the folder the game scans for mods.
5. Check that the copied files exist and have plausible sizes. Keep a simple list of the versions and dependencies you are about to change.

Automatic save backups can be useful, but they are not a substitute for a separate copy made before a deliberate change. A synced folder also is not the same thing as a retained backup: a deletion can synchronise too.

Choose a trustworthy FS25 release

The official ModHub, reached through the game or the GIANTS website, is one starting point. External releases should come from the creator’s own hosting page or a destination that the creator explicitly approves. An external release is not automatically bad, and a familiar screenshot is not proof of origin.

Before you download, establish:

• Game: the listing explicitly says Farming Simulator 25. A similar FS22 filename does not make it an FS25 release.
• Platform: the release is intended for your PC installation. Do not assume script mods or third-party downloads are available on consoles.
• Requirements: required game patch, DLC, supporting mods, new-save instructions and installation notes.
• Ownership: who made the original work and who made any edit. Use the correct creator’s support channel.
• File: the actual ready-to-install release asset, not an advertisement, launcher or repository source archive.

On GitHub, the green source download button can produce a repository snapshot. It is not necessarily a player-ready mod. Follow the project’s release instructions. For example, Courseplay release 8.1.0.3, checked 10 September 2026, names its packaged FS25_Courseplay.zip release asset. GitHub identified that as its latest published non-prerelease on the check date; this is a dated snapshot, not a permanently current version claim. The official ModHub listing also showed 8.1.0.3 on the check date, with its own publication date. GitHub’s non-prerelease flag does not override the creator’s developer-version guidance. This is a packaging example, not an instruction to use a development build on a working save.

Keep the original hosting page in your notes. Its requirements and credits matter, and linking there preserves any pricing or donation choice. The TW Farms Mods & Maps hub links to the existing release pages rather than republishing their ZIPs.

Check the ZIP before installing

A normal installable FS25 mod ZIP contains modDesc.xml at the archive root. This descriptor tells the game about the mod. It must be accompanied by the files the mod actually needs; a descriptor alone is not enough.

Open the archive in File Explorer or your normal archive manager to inspect it, without extracting it into the mods folder. Turn on filename extensions in File Explorer so you can distinguish .zip from a misleading name such as .zip.exe. Exact controls differ between Windows versions; find the file-extension option in File Explorer’s View controls.

A simplified, illustrative package looks like this:

FS25_ExampleMod.zip
├── modDesc.xml
├── icon.dds
└── [the mod's other files and folders]

The example name is fictional. A real mod may have very different supporting folders or an image in another format. The important check is where the descriptor sits, not whether every package resembles this drawing.

Spot wrappers and nested archives

These layouts need investigation before installation:

DownloadBundle.zip
└── FS25_ExampleMod.zip

FS25_ExampleMod.zip
└── FS25_ExampleMod/
    └── modDesc.xml

The first may be an intentionally bundled download: follow the author’s instructions and take out the individual installable ZIPs, leaving those inner ZIPs intact. The second may be a source-code archive or incorrectly wrapped package. Find the ready-made release rather than improvising a repack. Do not flatten folders inside someone else’s mod to “make it fit”.

If your archive manager offers Test, use it to check archive integrity. Opening a ZIP’s directory only proves that its directory can be read; a full test reads more of the contents. An integrity failure, unexpected end of file or a suspiciously incomplete download calls for a fresh download from the same approved page. A successful archive test does not prove compatibility or trustworthiness.

Find the active mods folder

For a standard Windows installation using Documents, the usual location is:

Documents\My Games\FarmingSimulator2025\mods

That is a path relative to your active Documents folder, not a literal command and not the game installation directory. The game’s installation folder contains the program; its user-data folder contains your log, settings and saves.

1. Open File Explorer and open Documents from Windows’ known folders.
2. Look for My Games, then FarmingSimulator2025.
3. Look for log.txt beside the mods folder. File Explorer may display the file as log when extensions are hidden.
4. Confirm that the log’s modification time belongs to the session you just ran. If you have not launched FS25 yet, launch to the main screen, exit normally and check again; do not create several guessed folder trees.
5. Read the log’s Mod Directory entry where present. It is better evidence of the actual folder being scanned than an old shortcut.

An optional read-only PowerShell expression asks Windows where Documents currently is and appends the standard FS25 folder name. It does not create, move or modify files:

Join-Path ([Environment]::GetFolderPath('MyDocuments')) 'My Games\FarmingSimulator2025'

Copy the printed path into File Explorer. This expression finds the usual user-data candidate; it does not override a custom game configuration or prove a Microsoft Store installation uses that mods location.

Documents, OneDrive and custom locations

If Documents backup is enabled in OneDrive, Windows may route Documents through OneDrive. A manually typed default user-folder path can then point at an old, inactive copy. Use Windows’ Documents location and the fresh log together. If a file is cloud-only, ensure it is downloaded locally before expecting the game to read it. Do not turn OneDrive backup off or move the whole Documents folder merely to fix one missing mod.

A custom mods-directory setting can also change the answer. Read the active log; do not edit settings just to make them match this article. The inspected TW Farms configuration had no active mods-directory override, but yours may.

If the expected log does not exist, check that you launched FS25 rather than an older game, are looking in the Windows account that launched it, and are using that installation’s user-data location. Stop guessing if the evidence disagrees; use the log location walkthrough.

Install one release and its dependencies

With the game closed, copy the installable mod ZIP into the confirmed active mods folder. Keep the ZIP zipped for normal player use. A creator’s special instructions take precedence for supporting files, but extracting every mod “just in case” creates more uncertainty, not less.

Keep a single intended copy of each mod in the active folder. Keep rollback copies somewhere else. Browser-added suffixes such as (1), renamed “new” copies and a ZIP beside an extracted duplicate can obscure which package the game is reading.

A maintainer-diagnosed filename case explains why this matters: suffixed AutoDrive and Courseplay downloads were rejected, and the reporter confirmed fresh downloads worked. Issue 366 is closed and concerned FS25 1.10.0.0 / AutoDrive 3.0.0.6; this was a resolved configuration problem, not evidence that every missing mod has the same cause.

Preserve the creator’s intended filename. A sensible mod identifier uses letters, numbers and underscores; if a download gains spaces or punctuation from your browser, re-download cleanly or restore the exact published name. Do not rename unrelated mods to make them look alike, rename one mod to impersonate another, or change descVersion to force an incompatible package to load.

Read requirements as part of installation, not after the game fails. If a map requires a supporting package, install that package from the location the map author supplies. Dependencies can need enabling alongside the main mod. Paid DLC, a script dependency and an optional recommendation are different things: check which one the release page actually describes.

Verified example: the MultiMap Edited 4x By TW Farms page lists FS25_MapsSupplementaryPackage as required and supplies it on the same page. Copying only the edited map ZIP is not a complete installation. This is a dependency example, not a claim that every map uses a supplementary package.

Enable the mod for the save

After copying files, start FS25 again so you test a new scan rather than relying on what a still-running session remembered.

1. Check the game’s installed/downloadable-content view for the intended mod, if it is listed there. An external mod appearing as installed is not the same as enabling it for a particular save.
2. Start or select your test save. During the loading/setup flow, review the offered mod-selection list and enable the desired mod and its required dependencies.
3. For a downloaded map, choose that map when creating the test career. Installing a new map does not convert your existing farm into it.
4. Continue into the test game and wait for loading to finish before judging the result.

The precise screen labels and buttons are still awaiting TW’s hands-on confirmation for the current patch. The reliable distinction is installation versus selection for a save; do not look for an invented “activate globally” button. When a dependency or required mod is missing, cancel and investigate instead of agreeing to continue with an incomplete main save.

Prove that it loaded and works

Decide what a successful test looks like before doing it. “The loading screen went away” is weak evidence for a production mod; “the production is present, can be placed in a test save and performs the documented basic operation” is a useful check.

1. Look for the expected item or feature in its relevant game location. A map, vehicle, production and script feature will not all appear in the same shop category.
2. Carry out one small representative action with base-game equipment where possible. Avoid adding three other new mods to the experiment.
3. Exit normally and inspect the current session’s log for the intended mod identifier, its version where reported, and errors during loading or use.
4. If you need to confirm persistence, use the disposable save: save it, restart and check the result. Do not use your only production save as a persistence test.

A log entry naming a mod can mean the package was discovered; it is not proof that all of its scripts or assets worked. Conversely, the absence of the exact word Error does not guarantee a working feature. Combine the log with the action you actually tested. See first useful errors.

Update without losing your rollback

Treat updates as a controlled change, especially for maps, scripts and productions already embedded in a save.

1. Read the creator’s changelog and migration instructions. If it requires a new save, do not assume your old save is exempt.
2. Close the game/server and back up the working save, settings and current mod versions.
3. Download the new release and its matching dependencies. Record where they came from.
4. Move the previous ZIP out of the active mods folder, then install the replacement with its intended filename. Do not leave two variants competing in that folder.
5. Test a disposable save first; then test a copy of your established save if the update supports existing saves.
6. Compare the new session’s behaviour and log with the pre-update baseline. Keep the old setup until the update is demonstrably usable.

If you have already saved with an update that changes stored data, swapping back just the ZIP may not undo those changes. A safe rollback restores the matching save backup and mod set together. Stop rather than experimenting on the only surviving copy.

Match a multiplayer setup

A multiplayer installation is a shared configuration. Ask the host for the exact approved releases and requirements, rather than collecting similarly named files from different sites.

• Match the game patch, required DLC and enabled mod/dependency set expected by the host.
• Use the same actual release files. Equal filenames or displayed version numbers alone cannot prove two edited ZIPs contain the same data.
• Ask which packages are required for that server; not every file on someone’s PC belongs in your local test set.
• Do not update one player’s mod independently during a shared session. Agree a change window, back up the server save and update the coordinated set.
• If the join flow reports a missing or mismatched mod, resolve that specific requirement before diagnosing an unrelated network problem.

Do not send paid packages or private server material to other players without the right to do so. Link them to the authorised download. For unexplained loading failures, GIANTS recommends a fresh no-mod test; a mod mismatch and a connection failure can look similar from the loading screen. Keep the server’s real save out of that experiment.

Remove or isolate a suspect safely

First preserve the failing log. Then close the game. Move the suspect ZIP to a clearly named holding folder outside the active mods directory, instead of deleting it. Keep a note of the exact file moved and any dependencies it needs.

Use a new stock-map save for a no-mod baseline. Do not open and save your mod-dependent farm with half its content missing. Keep required dependencies with a mod during testing: separating a map from its compulsory production pack can manufacture a new fault unrelated to the original one.

If removing one addition restores the test, put it back and repeat once where safe. A repeatable change is stronger evidence than a lucky reload. If many mods may be involved, use the half-split isolation method, which keeps dependencies grouped and checks both halves for interactions.

For permanent removal from a working save, consult the mod author. You may need to sell or remove placed equipment first, but the exact process depends on what the mod stores. If no reliable removal process exists, retain the mod or use a new save rather than promising that deletion is harmless.

Follow the missing-mod decision path

Work from discovery to selection to behaviour. Do not start by reinstalling the whole game.

Decision route: no current log → confirm the user-data location. Current log but no package discovery → inspect folder and packaging. Package discovered but no feature → check selection, requirements and use instructions. Feature present but failing → reproduce the smallest action and follow the log guide. Still failing with no mods on a new stock map → investigate the base game/environment rather than blaming the last download.

Finish with a working-state checklist

Tick these only after doing them. The checkboxes are a reading aid for this visit, not a claim that the website tested your game; they are not saved between visits.

If you cannot tick the test or log item, stop here and follow Finding, Reading and Using the FS25 log.txt. A methodical ten minutes beats an evening of renaming ZIPs and hoping for the best.
