What are? .fr-NUIjmj and so forth... files in home folder?

Hello!

Every time I open text files in File-Roller (previously compressed) and edit them, these text files are always saved in my Home folder.
in plain text.

e.g. folder (incl. text file)
.fr-NUIjmj, .fr-pLE5mK etc.

Can I export this path to another?
(from home folder to as example /tmp)

Or disable it?

Pluma/Leafpad saves every time in my home folder these above mentioned folders incl. text files.

I hope you know what I mean because I can't explain it better.
Greetings!
