The FileSide program, without asking me, settled in the directory:
C:\Users\User\AppData\Local\Programs\FileSide
In this folder of 66 programs installed on my computer, only Nord Vpn is located.
Also, it didn’t leave an icon on my desktop after its installation.
I had to manually install it to be able to include FileSide.
This behavior of the program puzzled me a lot and that’s why I removed her.
