Does anyone have personal experience with a program that will take an *.ARC file and unpack it? I have an old survey plan I did 25 years ago and compresses it before I stored it. Now I need the file, but have no program to rescue it.

Try WinZip.
According to this kb page you may need an older version however.
7-Zip is pretty versatile. It maybe could handle.

Thanks, I checked the 7-zip and it doesn't seem to list ARC files.
Do a search for pkxarc.exe, part of the old PKWare (Paul Katz). I used to have it but can't find it now. I also recommend you download and run it on the oldest, least important machine in your shop (don't we all keep at least one). Transfer the EXE to the old machine via USB, etc and make sure the old machine isn't on the network.

I thonk you need PKUNZip. I archived it on every CD that I copied archived files onto. I'll see if I can dig one out of a box somewhwere...
EDIT - Found it! If I can find your email address I'll send it to you...
Boy, this takes me back. Remember the arc vs zip wars and trying to squeeze the last byte onto a 5 1/4" floppy?
I don't think any of the zip utilities will work - wasn't Katz prevented from using the format, so he created zip, and arc died soon after?
Anyway, I dug out my old backups and found PKXARC.COM complete with documentation and a file date of 4/27/1987.
If you still need it I can send it to you, or if you send me the file I'll try to xarc it for you (I have a WINXP machine for running all my old DOS programs).
Just don't send it on a floppy!

Thanks.I'd like to try the pkxarc, since I remember the PKWARE name, and I have a few hundred files all ARC'ed and sealed in King Tut's pyramid.
You can send it to cerolli@yahoo.com.
Thanks from NH!

Jim,
Thanks! I'd like to try your program to see if it will unzip my file. You can send it to cerolli@yahoo.com. I appreciate it.

PKXARC.COM & ARCE.COM are both on their way - I hope one of them works!

PKUNZIP is on it's way from here. I am not sure if it is a standalone program or not, the folder contains about 15 programs that may need each other to run.
When I archived my old work files I put the compression software on the every disk along with the data files so I would have them in the future (which is now!)

Thanks! I'll let you know.

Jim, Why didn't I think to do that? Thanks! I'll let you know whether its successful or not.

Well, I've tried both programs and I don't have a machine old enough to run the blasted things. I'm going to just resort to re-entering the plan coordinates and re-draft it. I think that would be safer and easier than trying to use the old program.
Thanks for trying to help.

If you want, send me the archive file and I'll try to unpack it. I have a computer set up just to run my old DOS programs.
Chris, you can send me the file. I have a machine that has 'Power Archiver' on it which claims that it will decode them.

How do I send you the file?

Hi Chris-
You have my email from when I sent you the unarchiver programs, but I also just started a "conversation" with you including my email (which I think works as a way to send a private message here).
Gro,
Mark Silver was able to put his finger on a program and machine that worked like it had been waiting for years to prove it was still worth it's salt. It unpacked my 26 year old plan and I'm off and running.
I appreciate your willingness to help me out!
Thanks, Chris Rollins in NH

Great! I'm glad it worked out.
I remember saving my jobs on individual floppy disks, thinking that in 20 or 30 years I could put the floppy in this here..uhh..in the...dammit! There's no more floppy drives!

CD's and DVD's will go the same route as the floppy. I have an acquaintance who is involved in archiving data from space probes - they quit using optical media for archival purposes about a decade ago.
