up to my knowledge, TSM respects the limits of underlying file system. A years ago I had similar problem, it turned out to be caused by really too long names, too long in terms of NTFS. However, we were able to create such long names in NT with following scenario: mount a directory , e.g. c:\tmp\ under drive letter (D:). Now create files under d:. Limits apply to sum of directory name length plus file name length. Create file with maximum file length. Now access same file using c:\tmp path. In this case, the file name increased by length("c:\tmp"), thus went beyond allowe limits. I forgot the exact limit, I do not know exact versions of NT where this behaviour apply and whether it changed in later version, so you only can check whether this might be your problem. regards Juraj Salak Linz, Austria -----Ursprüngliche Nachricht----- Von: Glass, Peter [mailto:[EMAIL PROTECTED]] Gesendet am: Donnerstag, 12.

The file names in question are indeed quite long. Does anybody know the TSM standard on file name lengths? Can somebody point me to which TSM docs discuss this specifically? Thank you!
