Hi CHSM!
I had this error quite a lot times.
The fastes, best working an easiest way is to take a backup of this file (directory DATA\backup\w\wshaaaaa) and to put it back to the DATA\w - directory.
If you can't find this file in the backup- directory you will be happy to have an olde Backup of your complete Database.
The files without a suffix (such as .a or .b) are info- files to the same file with suffix, which contains the Source Safe data. These "nonsuffixfiles" store the information to which file in the VSS- DB the "suffixfile" is related to.
You can try to find out which Source Safe file your wsh.... belongs to by checking out your projects. VSS promts every file that is beeing checked out. VSS will prompt you if a file is missing. The file in the DB which schould be checked out next is the file who belongs to the wsh.....- file. You can delete this file, as the information is lost anyway. Now VSS should have no problems with the archive.
