ProjectWise only supports characters in folder or work area names that the operating system supports in file system folder names. You will get a warning if you try to create a folder or work area with invalid characters in the name. Folder descriptions can still use extended characters.

For legacy reasons, ProjectWise will let you use the "\" character in folder or work area names (it will warn you first, but it will still let you). If you later try to export such a folder or work area, two local folders will be created, with the portion after the "\" becoming a subfolder of the portion before the "\". For example, if the folder name in ProjectWise is "DGNS\DWGS", then after export, "DWGS" becomes a subfolder of "DGNS" on the file system.
