Files with the format **_, like EX_ and SY_, are identified as "compressed files of the normal extention."
So if EX_ is a compressed EXE, and SY_ is a compressed SYS, and so on, how do I decompress them so they work right?

Hi,
Your os is not N/A
In 6.22, if you type EXPAND, you get this msg:
E:\dos622>expand
Type the location and name of the
compressed file you want to expand
(Example: A:\EGA.SY_)Compressed file:

If you're trying to expand Windows 3.1 files (using Windows expand.exe) the format is as follows:
"expand somefile.ex_ somefile.exe"
(assuming you want the decompressed file in the same directory) or, conversely:
"expand somefile.ex_ a:\somefile.exe"
if you want to move it to a floppy.
Files in Windows 3.0 were compressed to a format with the same extention, thus:
"expand somefile.exe somefile.exe"
probably wouldn't have worked since you would overwrite the file while trying to decompress it.

As is so often the case, parameters can be shown by
expand /?

Okay, thanks. The only problem I have now is that I need to expand some files with the "HL_" extention, and I don't know what the full extension should be.
I assumed "HLP", but that doesn't work.
Anyone know?

Maybe some context? Specifically (with details) - what are you doing?
I'm just looking for clues at the scene of the crime

I'm taking my MS-DOS 6.22 install disk set, copying all the files to my computer, and expanding all the files that are compressed.
Files with the HL_ extention include DEFRAG.HL_ on disk1 and HELP.HL_ on disk2.

Of course, you know setup will do that automatically?
Defrag.hl_ does indeed expand to defrag.hlp - why do you say "that doesn't work" (which is just wonderfully informative) ??
DOS 'HLP' help files are in a different format than Windows files with that extension - you can't use Windows Help to open them - only by invoking the help function from the program in questionSomewhere on those disks you may have the list of files to show you what expands to what (filelist.txt?)

I was under the impression "they didn't work" because I tried to open them in windows and couldn't. I didn't know they had a different format. Oh well.
And the only reason I'm bothering with this is that setup didn't do anything automatically. Executing the setup.exe file on disk1 gives a message to restart the computer and let the disk boot to the install program.
If I try to boot from disk1, however, I get the generic "non-system disk" error message that you get when you try to startup with a non-bootable disk in your computer.
So maybe I've done something wrong entirely.....

Yeah, well what you're doing will be pretty tedious (if it isn't already) - if you can find that list, it may help somewhat - you won't need to expand every single file either.
Can't recall for sure, it's been many a year since the one time I ran DOS 'setup' - you could likely copy the necessary files from disk1 to a basic 622 bootdisk and proceed from there.
Besides expanding the files, setup 'sets up' some things - autoexec.bat & config.sys, as well as selecting the appropriate video driver for the Dosshell file manager - although anymore, only the VGA one is required.

You cannot open HELP.HLP by itself. You open it with HELP.COM, also you need QBASIC.COM in the same location.
DOSSHELL is not on the MS-DOS 6.22 Install Disk Set. It was withdrawn from MS-DOS 6.2 onwards, and moved to the Supplemental Disk (Sometimes called Disk 4) which has its own SETUP.BAT file - I have a reconfigured VGA copy on my PowerLoad DOS page ready for use, As well as the MS-DOS 6.0,6.2,6.21 & 6.22 Supplimental Disks.
HTH

I stand corrected (it was a long time ago), but I do recall puzzling over the compressed files then, much like aero is today ; )
(and setting up dosshell for EGA)

As posted elsewhere. I installed MS-DOS 6.22 onto a clean spare harddrive many moons ago and saved all the expanded files onto floppy disks. I now have CD-ROMs with such files stored on them. Not that I use them as much as I used to.
Yes jboy time does indeed blur the memory, thats why I am glad that there are still sites such as Computing.Net to keep the knowledge alive.

If they're indeed DOS disks (an imaged version or the true blue originals) then you should be able to boot from them (they should have a version of command.com and io.sys on them). "Setup/g" should allow you to install it without having to go through the routine of backing up the old version of DOS (which you apparently don't have). You may be able to find or create a version of a DOS 6.22 boot disk (assuming that's the version you're using) and boot to it and install the rest of DOS with what files you have. Just remember, if that's the case, you'll need the same EXACT version of the bootdisk...

You can get a MS-DOS 6.22 Bootable Image from my Bootdisk Project Page, which I think you have already visited to obtain Disk Copy Pro.
And by copying the rest of Install Disk One onto the bootdisk re-create a bootable setup disk.
One other point to bear in mind is the disk label. If it is not set as
DISK 1Thats DISK followed by 6 spaces then 1
You will not get past Disk 1 if you try to use them. Disk 2 & 3 need to be labled in a similar fashion.Please reply with a message to let us all know we are on the right track...

Hey Mick,
In case nobody ever told you, you got a real good site there. Didn't realize you had that much about DOS...

Mick's site is one of the first ones I discovered when I finally got online.
A 'must visit' : )

:-) Well its nice to know my work was not in vain.
I got a post on my Message Board
"Hi Man, When are you going to replace this old rubbish? Your site is getting really stale..."
Good God 'man' thats the point! Says I ...
Long live DOS ;-)

Not in vain indeed!!! Your site , along with Lightspeed's and PcFreak (now Zero Sky?) were critically important for me when i first started learning about PC's..still the very first pages i bookmark when I put a new box together...Kudos!!!

When a 120Mb hdd was a big drive I spent a lot of time deleting "unnecessary" DOS and Windows files. I spent more time typing commands like:
expand a:\help.hl_ c:\dos\help.hlp
It takes quite a while to expand a slew of files that only took a second to delete.
Mick's site and the OldFiles network is directly responsible for giving new life to about sixty 286, 386, and 486 machines that have passed through my garage. They all left home with working internet and network connections and most of them are still at work daily. Plug a cash drawer and receipt printer into a serial port and you have a working cash register or point of sale terminal. Spend 5 bucks on Works 2 or 3 and you can run your business. Brand spankin' new DOS/Win3.x operating systems cost less than twenty bucks.
And, if a file gets deleted or corrupted...expand is usually a quick fix. As larger harddrives became available, I'd just copy all the compressed files to the DOS directory. Makes for less typing to expand the files.
Skip

Just a quick plug, The Oldfiles Network which is a partnership between PowerLoad & LightSpeed with other Classic DOS & Windows Sites is at:
Other related sites are invited to jion the Network

Hi Gang,
Good mileage on this one; 21 replies and counting.
Aero,
since your OS is n/a, you can go to a box runnung 2k [maybe or XP] and copy everything into an empty directory and:
for %%F in (*.ex_) do expand %%F %%~nF.exe
For homework, write the additional lines needed to expand the other extensions.
Hint: .38_ expands to .386
OBW, since you tried to 'use' a 6.22 .hlp file and it 'didn't work'. Lemme guess, you're a;ready running Windows, roght?
If you manage to get useable 6.22 onstall disks, which these guys have told you how to do, are you planning to install 6.22 on a win9x box?
If so, I think you should regroup.
