Tablet A8 storage issue disk full with unknown content

[MaartenBXL]

Hello,

My new tablet is filling up the disk and I can't see what is the root cause.  I already checked my documents and other folders via the file manager but I can't find the reason. The issue is the space used by overige

Hello! The Others which you have 21GB includes:Cache of apps, useless files, Trash (of My Files, Messages, Gallery, etc). Try to clear them.

I already tried this. all the folders are empty. It's filling up by itself. I only received the tablet 3 days ago

Then you should try to reset your Tab🤔

that's no solution, I just finished configuring it

Overig appears to be your apps and app data which I'm assuming you have just installed,

I checked all apps one/one, nothing found.

Try installing DiskUsage app from Google Play, this will give a more detailed breakdown.

Google Files is the app I use to stop my Tab A7 filling up with crud. It's very easy to use and can be used as a File Manager too if desired. I just use the cleaning bit though
