Spotify - How to reduce and limit the cache size (Windows - Mac).md

WINDOWS

Use your text editor of choice or if you don't have one use Windows Notepad
Opening with Notepad may or may not result in a fancy mess

1. Close Spotify
2. Open File Explorer and paste the following into the address bar %appdata%/Spotify¤
3. Open the file named prefs with your text editor
4. Change the numeric value following storage.size= . If storage.size= doesn't exist add it manually to the end of the file and assign numeric value. This value represents megabytes. One gigabyte equals 1024 megabytes. In the end, it should look something like this storage.size=1024
5. Save the file
6. Start Spotify
7. The cache should be reduced; not exceeding the size that you entered
8. To verify, check the size of the Data folder in the following directory %localappdata%/Spotify

¤ For the App-Version of Spotify on Windows 10 use %localappdata%\Packages\SpotifyAB.SpotifyMusic_xxxxxxxxxxxxx\LocalState\Spotify instead of %appdata%/Spotify, credit to @SawPsyder

Mac

Apple TextEdit.app works fine to open "prefs" or one can use some similar code editing program

1. Close Spotify
2. Open Finder and press ⇧ + ⌘ + G or Open Spotlight (⌘ + Spacebar) and paste the following into the address bar~/Library/Application Support/Spotify
3. Open the file named prefs with your text editor
4. Change the numeric value following storage.size= . If storage.size= doesn't exist add it manually to the end of the file and assign numeric value. This value represents megabytes. One gigabyte equals 1024 megabytes. In the end, it should look something like this storage.size=1024
5. Save the file (⌘ + S)
6. Start Spotify
7. The cache should be reduced; not exceeding the size that you entered.
8. To verify, check the size of the Data folder in the following directory ~/Library/Caches/com.spotify.client/

Don't have a prefs file there and creating one and adding the line doesn't seem to change anything.

What I do have is a LocalPrefs.json file, but the schema doesn't seem to lend itself to adding anything about storage size:

{
    "os_crypt": {
        "encrypted_key": "A LONG STRING HERE"
    },
    "profile_network_context_service": {
        "http_cache_finch_experiment_groups": "None None None"
    }
}

what @dmwyatt said... any new solutions?

@dmwyatt go to the roaming spotify folder, not the local one.

To me, it reduced from 8.8Gb to 3.4. Does this file get overwritten on updates?

Has anyone found a non-official solution to limit the cache size on Android?

    }

I quickly realised that is a different file. The one you need to edit is simply prefs.file. Provided that you are on Windows, I found that it is stored in: C:\Users\user\AppData\Roaming\Spotify

Thanks for the solution.

The path of app version should be:
$AppData$\Local\Packages\SpotifyAB.SpotifyMusic_*******\LocalState\Spotify\prefs.
Generally just go to $AppData$\Local\Packages, search for spotify, open it. Search for prefs. There may be several. Choose the one under Spotify rather than user.
