problem of saving solidworks files

[GGG35]

Hello, everyone. I'm working in a solidworks set. for a couple of days I can't make progress in editing and creating parts because after their creation I find it impossible to save them in the usual directory where I have worked so far. When I try to save the modified parts, I have an error message: "unknown error during access to [Percorso Directory]".
Would anyone know how to solve this? Thank you very much to those who answer. I attach screenshots.

network or local? Are there administrative rights?

d: is it a pen drive?

I happened a similar error while working with solidworks on files directly from a pen drive... to fix the problem I had made a pack and go of the axieme and saved it in a folder on the desktop. Then I always worked inside that folder and the problem no longer showed up.

Is that the problem? Let us know
