@thatbrickster Yes, and as soon as you are not storing notes for years, it looks like media files take the most part of the storage.
And that files really could be stored in the "cache" storage space.
I'm planning to add a separate setting to limit media files storage. Currently media files are deleted only after corresponding notes have been deleted.
Tip for now: In order get rid of all media files, you can:
1. Create backup of #AndStatus data ( it doesn't contain media files)
2. Uninstall AndStatus
3. Install the same version of AndStatus and
4. Restore backup on the first launch.
