That makes sense but how about file names? I figured out that i can't copy some files till I change their names. Are there any special characters that cant be used? (comma?).
For example:
Addams Family, The (USA, Europe).png - critical transfer error (Filezilla)
The Addams Family.png - copied after name changing
RBI Baseball 93.png - critical error
RBI Baseball 94.png - copy success without any name changing
