how to upload new database into football manager

By /

If you play Football Manager, sometimes you may want to use a custom database — for example a current squad update, a retro database, extra leagues, or a fan-made league mod. These “databases” modify the default game data: clubs, players, leagues, transfers, kits, etc. But simply downloading the database isn’t enough — you need to install it properly so FM recognizes it.

In this guide, I’ll walk you through:

  • What files you need
  • Where to place them on your computer (Windows / macOS)
  • How to start a new game with custom database
  • Common mistakes & troubleshooting
  • Tips & best practices for a smooth experience

1. What Is a “Database” in FM and What Format Should It Have

In FM, a “database” refers to a set of data files (players, clubs, leagues, competitions, transfers, history, etc.) that override or supplement the default data in the game. These can be:

  • Official data updates (e.g. latest transfers / squads)
  • Community-made databases (retro squads, real-name fixes, custom leagues)
  • Editor data (created or modified data using the FM Pre-Game Editor)

Usually, downloadable FM databases come packaged as archive files (zip, rar, 7z). Inside, you should find a file with extension .fmf (or rarely .xml) — this is the database file that FM reads. (SORT IT OUT SI)

Important: Do not put zipped/ archive files directly into FM’s data folder — you must first extract them so that the .fmf (or .xml) file is exposed. (SORT IT OUT SI)

2. Where to Place the Database File (Editor Data Folder)

For Windows

  1. Open “File Explorer”
  2. Navigate to:
    Documents > Sports Interactive > Football Manager XXXX > editor data
    (Replace XXXX with your version of FM, e.g. 2024, 2025, etc.) (SORT IT OUT SI)
  3. If the folder editor data does not exist, create it manually. (SORT IT OUT SI)
  4. Copy the .fmf (or .xml) file into this folder.

For macOS

  1. Open Finder
  2. Click on Go → Go to Folder, or press Shift+⌘+G
  3. Enter: ~/Library/Application Support/Sports Interactive/ and press enter (SORT IT OUT SI)
  4. Open the folder for your FM version (e.g. “Football Manager 2024”)
  5. Open or create editor data folder, and put the .fmf file there.

Make sure you have extracted the file from any zip/rar archive — the game will not recognise compressed archive files. (SORT IT OUT SI)

3. Loading the Database in Football Manager

Once you have placed the .fmf file in the correct folder, follow these steps:

  1. Launch Football Manager.
  2. Instead of loading an existing save, click “Start New Game” → “Career” (or appropriate mode). (SEGA Support)
  3. In the game setup screen, look at top-right: there should be a dropdown (database version selector). Inside, you should see your custom database(s). Tick (select) the database you want to load. (SORT IT OUT SI)
  4. Click “Advanced Setup” (if prompted), then proceed to choose leagues, countries, and other preferences as desired.
  5. Begin your career/save — the game will now use the custom database, with new clubs, players, leagues etc. active.

⚠️ Important note: custom databases usually only apply when you start a new game. If you load in a previously started save, the new database will not update existing save data. (Sports Interactive Community)

4. What If Database Does Not Show Up — Common Mistakes & Fixes

If you follow the steps but don’t see the custom database in FM, check the following:

  • File not extracted properly — make sure the file is .fmf or .xml, not still in .zip/.rar. (SORT IT OUT SI)
  • Wrong folder path — ensure you placed the file in the correct “editor data” folder under your “Documents/Sports Interactive/Football Manager …” directory (Windows) or Library → Application Support (macOS). (SORT IT OUT SI)
  • Game version mismatch — databases made for an older version of FM might not load on a newer version. Custom databases must match or be compatible with your game version. (FM Scout)
  • Attempting to load database in existing save — custom databases only load when you start a new game; they won’t retroactively change an ongoing save. (Sports Interactive Community)
  • Cache / preferences issues (rare) — occasionally FM may need cache reset or preferences reloaded if custom content fails to appear. (Sports Interactive Community)

If none of these work — double-check database’s readme/instructions, ensure compatibility, or try with another custom database.

5. Why Use Custom Databases — Benefits & Use Cases

Using custom databases in FM gives you many advantages:

  • Updated squads & transfers — get real-world squads and transfers before official updates.
  • Retro football / historical databases — relive past seasons with historical teams, players, kits, leagues.
  • Fantasy leagues & modded leagues — add leagues that don’t exist in the default game, or create your own custom league structures.
  • Local leagues or niche countries added — if default game misses certain countries/leagues, a custom DB can add them.
  • Enhanced realism / community fixes — real player names, badges, kits, accurate stats, and community-improved data.

These databases allow you to shape the game world exactly how you want — more realism, nostalgia, or creativity.

6. Tips for Smooth Database Use & Good Experience

  • Always back up your saves and existing database files before adding or changing a custom database.
  • Use clean, verified databases from trusted community sources (forums, well-known FM mod sites) to avoid corrupted files or crashes.
  • After installing new database, start a new career so data loads properly — avoid mixing old saves with new DB.
  • If you have many custom databases/ mods (graphics, data, logos, kits), enable/disable them one by one to identify conflicts.
  • Avoid incompatible old-version databases — they often cause missing data or game instability.
  • For maximum performance (especially with large databases), consider selecting fewer leagues or countries initially — large databases slow down game performance.

(FAQs)

Q1: Can I add a custom database to an already-started save?
No. Custom databases only apply at the start of a new game. Once a save is started, its data is locked and won’t update with new databases. (Sports Interactive Community)

Q2: What file formats does FM accept for databases?
FM accepts .fmf (common) or .xml files for databases. Always extract archives before copying — zipped files won’t work. (SORT IT OUT SI)

Q3: My custom database doesn’t appear in the dropdown when starting a new game. Why?
Common causes: file placed in wrong folder, wrong FM version compatibility, zipped file not extracted, or incorrect file extension. Double-check the path Documents/Sports Interactive/[FM version]/editor data.

Q4: Where can I find custom databases for Football Manager?
There are many community websites and forums (e.g. fan communities, FM mod sites) where users share updated squads, custom leagues, and historical databases. Always ensure they match your FM version before using.

Q5: Does using custom databases affect game performance?
Yes — large databases with many leagues, clubs, players can slow down save generation, AI processing, and overall performance. If performance lags, try reducing number of loaded leagues/countries.

Conclusion

Uploading a new database to Football Manager is fairly simple — as long as you follow the correct steps: extract the file, put it in the right folder, and load it when starting a new career.

Whether you want real-world squads, retro football memories, or custom leagues, custom databases offer endless possibilities to enhance your FM experience.

Just remember: always backup, ensure compatibility, and start a fresh game to avoid problems.

Now you’re ready — download a database, install it properly, and enjoy your customised Football Manager world!
