It seems to be a Linux thing, not a file system thing. ---- You might want to look closely at the file names in Linux. Windows is not case sensitive but Linux is. In Windows, you cannot create the 2 files, TEST.DOC and test.doc in the same directory but in Linux you can. It may be that some of these files are stored differently as in file1.ps and FILE2.PS etc. Also, you might want to check out some alternate settings... dos filemode = yes (Share setting only) case sensitive = no (share setting only) default case = lower (share setting only) Craig
