Thanks for the info. But this really sounds like the designer(s) of
HPFS really haven't thought it through when they design it. Just imagine this:
You have created a file on HPFS with filename abcdefghihj.klmnop.qrstuv,
on you hard disk. But then there's no way for you to back it up on the floppy
with the original name. So you save it with abcdefgh.klm . So what's the use
of HPFS anyway ?
PS: Hey, IBM and MS, here's one problem that should be solved with version 2.0.Anyone has information about this ?

OS/2 comes with a program which copies the full file information, including the full filename, to floppy. For the life of me I can't remember what the name of the command is. I guess that it stores the full name as an extra EA on the floppy. -- Conrad Bullock | Domain: conrad@comp.vuw.ac.nz Victoria University of Wellington, | or: conrad@cavebbs.gen.nz New Zealand. | Fidonet: 3:771/130 | BBS: The Cave BBS +64 4 643429

If you copy the file with the long name from HPFS to the floppy using the PM file manager, it creates a EA ".LONGNAME" containing the original name. When restoring the file back from the floppy onto a HPFS using PM file manager again, it recognizes this EA and renames the file to its original name. You have more choices. You can use an archiver that supports long HPFS file names (ZOO, C-LHarc, LH2 or the ZIP coming soon from Info-ZIP) to put the file into an archive on the floppy. Also, you can create TAR floppies with GNU tar for OS/2 just like under Unix and read the floppy onto another HPFS.
