error code -8058

The recommendation to rename files seems to be on the mark.

I was having the problem when copying files from a PC then noticed that the files that were causing the problem had characters that were non-English language. In my case, that was umlaut (a pair of dots above the "e"). Anglicising the spellings (dropping the umlaut) worked.

rename the file - then restart your computer - it worked for me

I have multiple unknown folders named Movies, Folder or Images everywhere within my own folders. I cannot delete them, and they tend to appear and dissappear on their own.

What do you suggest I do?

Thank you.
