Hello,
Some months ago I noticed that my system disk has less and less free space. Tried a cleanup but it marginally enhanced the free space.
Then going deeper I noticed that a directory used by Mozilla Firefox is really making it :
C:\Users\François\AppData\Roaming\Mozilla\Firefox\Profiles\wjZDDDl0.Profil 1\storage\to-be-removed
On may 13 I deleted all the subdirectory within and the free space went from 23 to 32 Go
Did it again today and up I went from 25 to 40 Go free space.
What are these files for and why are they not automatically removed as per name ?
Thank you.
