The issue is that files copied on a system A by user a are marked with the user-id of user a rather than the user name. If the files are then seen on system B where the user a has a different user-id then that user cannot easily access the files. One solution is to use a file sysem like FAT/VFAT that does not care about user id[*]. However, long file names can occasionally cause problems if this is not mounted correctly. There are other issues like fragmentation as well. When you want to copy files with permissions and other attributes use an archive like tar.gz or tar.bz2 or a loop device. Another solution using ext2/3 etc. is to mark all files/directories on the portable medium as world readable/writable. Perhaps that is what you meant. Regards, Kapil. [*] I feel some reluctance in suggesting this old FS but it is the only one which was _designed_ with floppies in mind! So it works well with portable media. -- _______________________________________________ To unsubscribe, email [EMAIL PROTECTED] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
