I believe the enhancements are non-trivial on account of the various
MicroSloth filesystems (FAT 12, FAT 16, FAT 32).  The filesystem used
by PCDISK and PCX doesn't work above a few megabytes.

There was a recent announcement of a crude mtools port that might handle
this problem if you're running a recent version of VMS (like v7.1).
I think Sergey Tikhonov has configured this to work only with a floppy
drive, but the code is there for the other formats.

Hello,

I made a quick port of Unix mtools to OpenVMS Alpha. If someone wants
take a look - the zip file could be taken from:
ftp://grace.solvo.spb.su/pub/mtools_vms.zip
Binaries are compiled on OpenVMS Alpha 7.1 with DEC C 5.7. Mtools
assumes the DVA0: as drive A: and
mount/dismount disk by itself. It doesn't preserve any file attributes
;(, but could be used to transfer zip files.
I am not planning to do more work on it (I am comfortable how it works
now), but if people show interest I would
work with current maintainer to include VMS specific code to current
release of mtools.

Thank you,
Tikhonov Sergey
