anyway to move the app folder openquake4

AppData\Local\OpenQ4 my hard drive c: keeps running out of space

Yes — you can put openQ4's user-data folder on another drive using fs_homepath and fs_savepath.

1. Close openQ4.

2. Create a folder such as J:\OpenQ4Data and copy the contents of %LOCALAPPDATA%\OpenQ4 into it, keeping the subfolders intact. For example, baseoq4 should become J:\OpenQ4Data\baseoq4; keep any mod-named folders too.

3. Add these options to your existing batch-file launch line or shortcut Target:

   +set fs_homepath "J:\OpenQ4Data" +set fs_savepath "J:\OpenQ4Data"
   

   Keep your existing fs_game / fs_game_base options. If the launch line already sets either path, replace that value instead of adding a second copy. Point both paths at OpenQ4Data, not at its baseoq4 subfolder. These are startup options, so put them on the launch line rather than in autoexec.cfg.

4. Launch using that shortcut/batch file and check that your settings and saves are present. After verifying the copy works, you can remove the old %LOCALAPPDATA%\OpenQ4 data to reclaim the C: space. Keep the path options on future launches.

This relocates the engine's writable data, including its configs, saves, screenshots, logs, and generated caches. You do not need to move the Quake 4 installation or edit mod.json for this.

The filesystem startup code reads these overrides before opening the user-data directories; the current windowed test also writes successfully to a separate save path.

added to my bat but not working
"openQ4-client_x64.exe +set logfile 1 +set fs_game_base baseoq4 +set fs_game hidef2kbc72 +set fs_homepath "k:\OpenQ4Data" +set fs_savepath "k:\OpenQ4Data""
ok screenshots worked but not the saves, also under baseoq4 not hidef2kbc72

Thanks for testing it. Your path settings were read correctly; the screenshots landing on K: show that. What went wrong is that openQ4 stopped finding the hidef2kbc72 mod, so it fell back to baseoq4 for everything.

openQ4 only accepts fs_game hidef2kbc72 when it can find hidef2kbc72\mod.json in one of three places: the openQ4 folder, the Quake 4 folder, or the save path. Most likely your mod was being found in the old save path, %LOCALAPPDATA%\OpenQ4\hidef2kbc72. With fs_savepath pointing at K:\OpenQ4Data, there is no K:\OpenQ4Data\hidef2kbc72\mod.json. So at startup the engine logs Ignoring fs_game 'hidef2kbc72': …, drops the mod and writes everything under baseoq4.

Saves and screenshots always go to the same folder. That's also why your saves seemed to stop working: the mod's saves are still in the old hidef2kbc72\savegames, while the load menu was looking in baseoq4.

To fix it:

1. Quit openQ4.
2. Copy the whole %LOCALAPPDATA%\OpenQ4\hidef2kbc72 folder to K:\OpenQ4Data\hidef2kbc72, including its mod.json, pk4s and savegames. K:\OpenQ4Data should hold baseoq4 and hidef2kbc72 side by side, with no extra OpenQ4 folder in between.
3. Launch with the same batch line as before.
4. Open the console and type fs_game. It should print hidef2kbc72, and your saves should be back in the load menu. If it doesn't, find the Ignoring fs_game warning in the console or in qconsole.log and paste it here. It says exactly what was missing.

The screenshots from your test run, and any saves made during it, are in K:\OpenQ4Data\baseoq4. Move the screenshots across if you want to keep them. Once the mod loads from K:, you can delete the old %LOCALAPPDATA%\OpenQ4 copy.
