Re: [Freedos-user] zip programs and pure DOS?
As Dennis and Ralf have said, the versions for DOS of Zip and Unzip are current. That's the nice thing about DOS, the interface is stable. Sounds like what you need is the zipfix tool. I think PKware had pkzipfix? Check for that and run it. That tool will check for errors in your zip files. BTW, asking for MSDOS help on a FreeDOS forum, and then saying no to that help because the FreeDOS folks gave an answer for FreeDOS, is a rather strange thing. It's like asking Linus Torvalds what his favorite Windows program is.

You probably don't *care*. I don't believe any updates made after 2009 affect the DOS versions. InfoZip is *very* mature technology, and updates past what the FreeDOS site has are almost certainly for Windows and Linux ports. (I just browsed current issues and patches. All are for Linux, POSIX, or Win64.) I suspect no patches that would affect use on DOS were in the older versions you found. DOS has been dead for 25 years. Patches only happen when someone reports a bug and someone else is motivated to create a fix. Given how long it has been since DOS ceased to be a widely used OS, I'd be startled if anyone actually found a bug in more than 20 years that *required* a fix. If you really want to be that fussy about " current" editions, you bite the bullet, install a version of Linux that will work on your hardware, and run DOS applications using DOSBox or DOSEmu. But the underlying issue you reported still exists. You have Zip archives that return errors when you try to open them with PKUNZIP. Where did they come from? Did you get them from elsewhere or create them yourself? If you created them yourself, where are they stored? (Please tell me it isn't on floppy disks.) Switching to Infop-ZIP isn't likely to magically fix the problem if the archives are damaged.. If you really need to get at the contents of those archives, you'll need to use a tool that can try to repair damaged archives. It's been a while since I've used it, but foggy memory says archive repair was not something the Info-Zip packages offered. I believe DOS versions of 7-zip do offer repair capabilities. > Karen __ Dennis ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user

It appears that the edition of info zip's zip and unzip programs are not current, from 2008 and 2009, according to my google. Unfortunately sourceforge no longer lets you download from there without JavaScript, these days. So my goal is the most current edition, which does not seem to be what you provide at the freedos site? I am not sure what exactly you are looking for. PK(un)ZIP is now almost 30 years old. The exact algorithms used are made public for everyone to use 30 years ago. So why would there be anything more "current"? Specially considering "pure DOS", which is officially dead for +25 years...

Re: [Freedos-user] zip programs and pure DOS?
Hi Jim, As stated, I do not use freedos. Is there an infozip archive package on the freedos site? My desire would be an install executable complete with documentation, as I imagine there are utilities for more than one platform.

We use Infozip, and include that in the FreeDOS distribution. The zip files are compatible with PKZip (PKWare opened up the file spec so anyone could make compatible zip files.) Try unzipping your file using InfoUnzip and see if that will extract them correctly.

Re: [Freedos-user] zip programs and pure DOS?
Hi Karen, as long as you do not need 8086 compatibility, both infozip and 7zip should work great for you for processing zip files. With 7zip, you can in addition also process 7z files, bz2, gz and tar files and some other formats if you like. While DOS PK zip was powerful at the time, infozip is more modern. As 7zip and infozip also have Windows and Linux versions, you do not have to worry about compatibility with other users either. http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.2/repos/pkg-html/zip.html (zip and unzip in freedos are by default the ones from infozip) http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.2/repos/pkg-html/p7zip.html Regards, Eric ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user

greetings folks, as stated often, while I do not use freedos, I am a strict DOS user. By which I mean, not using an emulation, with only DOS on my machines. For well ever I have used the edition of pk zip et, al. from 1999, which I believe was the last dos edition created by that company. I have a large archive of all text files, and am getting errors, creating sub directories, stating the file name is incorrect, even though the latter is wrong.
