I have a problem with profiles.

I usually back up the profiles to protect myself against failures or data loss.

Today I couldn't, some files with Chinese, Korean or Japanese characters appeared, I don't know which language, and the copy was cancelled.

Attached is a picture of the intruders.

These files cannot be renamed, copied or deleted.

Translation of the text:
The specified file name is not valid or is too long. Specify another file name

Any help or suggestions?
