OneDrive / SharePoint: File Naming Conventions
If a file or folder you’re trying to upload to OneDrive/SharePoint contains any of the characters listed below, it may prevent files and folders from syncing.
Rename the file or folder to remove these characters before you upload it.
“ * : #< > ? / \ |.
Leading and trailing spaces in file or folder names are also not allowed.
You can tell when there is a syncing error as the OneDrive icon in the menu bar will have a cross.
If you have several files with naming issues, there is a software program that can fix this for you. Please see the Tech Centre for further assistance.
