Too many folders and space on the home user: snap/APP


#1

Using snap packages for a long time, I realized that it creates many folders, also taking up space, this is an example of Chromium and Firefox, but there are also many folders on GIMP.
I noticed the space occupied because these folders are in a backup, I was restoring and I saw that it was moving a few GB, it is not normal for user folders only …
This behavior of SNAP in wasting space stops me from using the snap packages in my Desktop and other installations.

The problem is when will I install many snap applications, will I have many of those folders and space occupied?
What folders can I delete without losing configurations?
