Most characters in folder names and file names are supported with the following exceptions. If a file is uploaded with an illegal character, the software will either substitute any illegal characters in the filename with underscores, or reject the file/folder from import altogether. In addition, problematic characters, while not strictly illegal, can cause issues with encoding or workflows.
|Illegal characters||Problematic characters|
“ (double quotations)
! (exclamation mark)
$ (dollar sign)
][ (square brackets)
*Single periods are illegal in folder names, double periods are illegal in filenames.
