Box Sync 4.0 provides detailed user notifications if there an issue syncing a file or folder.
Some operating systems do not support item names containing some special characters. If you attempt to sync files or folders names containing these characters, Box Sync prompts you to rename the item using the underscore character.
Box OS-independent restrictions:
- Box does not support '/' and '\' anywhere in a file or folder name or whitespaces at the beginning or end of a file or folder name.
Windows OS restrictions:
- Box does not impose any additional restrictions.
- If Windows does not support certain characters in file names, Box marks them as problem files. See the list of Windows file name restrictions. Windows file name restrictions also shown below:

- : (colon)
- " (double quote)
- / (forward slash)

- Windows does not support folder names that begin and end with a . (period) character.
Mac OS restrictions:
- Box does not support opening spaces.
- Box does not recognize Mac’s character conversion in file names (for example, Mac changes any occurrence of / to : in file names).

If the item on Box has an unsupported name, rename the item on Box and Box Sync will re-process the download. If the local file has an unsupported name, rename the file locally.
