Hi,
First of all, I have read forums and searched in google.
I didn't see any usable solution.
4 of my folders have X and red in the corner. But inside of these folders I don't see any file or folder marked with X.
If you suggest some file may have some issue with characters, Please teach me how to find them.
I checked in here and it is empty.
