Downloading infozip or 7zip as zip files provided by the freedos community will not cause any problems for using infozip in ms dos or using 7zip in MS dos. Basically, any dos will do, even the very old MS dos. If you use long file names, the corresponding drivers should work on any DOS, too. Or use Windows 98 DOS without drivers. I still think that even old infozip or 7zip will be able to open files which much older PK zip for DOS may have problems with. In spite of PK zip being a high end product long ago when it was new.

It was Jim's comment, not my own. Having never used freedos for a variety of reasons I am not in a position, nor do I claim to be in a position to comment on its coding sources. Its why I stated from the outset that My request was for Ms DOS related tools . And why upon discovering that a freedos solution was older than the publicly available DOS one, I commented on that fact. Jim stated that was strange, since to ask about a DOS solution on a freedos list calling into question a freedos solution is strange. In my Dictionary, making a suggestion to use, not happening in the present situation, but in many instances previously a tool from a completely unrelated to the scope of this list operating system, is even stranger. may as well make windows or Mac ones, after all the Mac system is Unix based too. Shameful is in the eye of the beholder, so is strange, with those eyes starting with Jim's comment.

Re: [Freedos-user] zip programs and pure DOS?
Hi, From the little information OP provided, I'd guess that the issue might be rather related to missing LFN support - either in pkunzip or in her system, while the text files stored inside the zip archives may use long filenames or contain some unusual symbols (spaces...). Actually, speaking personally, I have always had long file name support. However, while the sub directory idea is an interesting one, that was not the problem. Nor does the file use names with extra spaces or strange characters..the person providing the file respects my needs, sharing some of them. I honestly am unsure why pkunzip triggered the error, because it created the subdirectories perfectly fine regardless. anyway the solution is found, with my now knowing it is wise to remind anyone suggesting Linux ideas or tools that this is a freedos list when that happens in future. Jim clearly prefers the focus be honored. Kare > Another possibility is that the zip files store subdirectories with a slash (/) instead of the legacy backslash symbol.

I will indeed run the pkware utility on my zip file. It is after all the first error in decades. I will also point out to those suggesting Linux solutions on a freedos forum the strangeness you hint at here. My search of the infozip site documentation indicated that those upgrades were for DOS. I already have the 7 zip program just rarely have reason to use it. Indeed pure dos is stable, a fine thing to be sure.

Re: [Freedos-user] zip programs and pure DOS?
What i was seeking, and found on my own, were copies of infozip that reflected their current editions of zip and unzip, from 2008 and 2009 respectively. Updates to their DOS programs created to incorporate greater file sharing and disk sizes. that pkware is 30 years old is irrelevant since infozip is not a pk product, just builds upon it. That my error using pkware editions of zip is the first I have encountered in more than those 30 years says allot for how solid, in a pure dos environment, the program still works.

Re: [Freedos-user] zip programs and pure DOS?
Hi Karen, > As stated, I do not use freedos. > Is there an infozip archive package on the freedos site? The links in my previous mail point to pages which link to both the official homepages of infozip and 7zip and to the freedos copies mirrored on ibiblio: The infozip copies may seem old, but this probably means that the dos version of infozip has not gotten updates from the maintainers recently. It still is a lot newer than PK zip for dos and supports modern file names and modern compression methods which may confuse old PK zip for ms dos. So I would still recommend to try infozip or better 7zip to unzip files which have troubled your PK zip. You can download both from our ibiblio mirror.

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

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
