DIXCOPY.EXE

DIXCOPY is a replacement for DOS diskcopy. It permits to copy a diskette
without swapping between source and target ... It uses XMS, EMS, disk (hard or
ram disk) in this order of priority and if there's enough space. I made it
efficient and easy to use.
To get help for running it, just type : DIXCOPY /?.
Options (number and path) are entered in any order. Number is 1 by default (if
not specified). Path is necessary if disk is used and you want to force the
location of the temporary file (if you have a ramdisk for example). If path is
not specified, or invalid, and disk is used then DIXCOPY searches for TEMP or
TMP environment variables, if they don't exist then it parses disks and uses
the root of the first one with enough space.
DIXCOPY detects if target diskette has the good format (it stops like diskcopy
if not) and formats it if necessary.
Copy can be aborted by Ctrl-C or Ctrl-Break.
Well, now for the good news : you can use and distribute these files, it's
freeware.
So ENJOY ...
* Examples
dixcopy b:
One copy of floppy in drive b:. Space for "disk image" is searched in
XMS then EMS and finally in 'TEMP' or 'TMP' directory. If neither is
large enough (or valid) then the root of first hard disk with
sufficient room is used.
dixcopy b: 2
Same operation but 2 copies.
dixcopy a: g:\foo
If not enough space in XMS or EMS and path 'g:\foo' exists, then it is
used for "disk image". This is (very) useful if g:\foo is on a ramdisk,
otherwise let DIXCOPY do the work ...
dixcopy a: g:\foo 2 (or dixcopy a: 2 g:\foo)
same operation but 2 copies.
* History
v1.0 (May 92) Initial version. Only disk support.
v1.1 (June 92) Adds XMS and EMS support.
v1.2 (Aug. 92) Corrects some bugs.
v2.0 (Oct. 93) Adds extended formats (820k, 1.72M, ...)
v2.1 (Dec. 93) Corrects some bugs :
- in some unusual case, format retries again & again.
- DMA buffer was badly computed : sometimes it crosses
a 64K boundary & SLOOoows DOOoown the process.
Speeds up a little bit the format/write procedure by
processing each track in turn instead of formatting all
disk and then starting through again to write data.
