Duplicate Files

SOLIDWORKS PDM warns you when you try to add files to the vault that have the same names as existing vault files.

A dialog box lists the files with duplicate names. It provides an option to export the file list in .csv format. When you click the hyperlink in the Current Location column, a Windows Explorer view opens that lets you rename the file you are adding.
Your administrator must select Do not allow duplicate file names in this vault for you to see the warning. This option is available in the Administration tool in the Duplicate File Name Check dialog box for File Types.

The warning also appears if you try to rename vault files using names that already exist in the vault.
