PKUNZIP 2.04G running in the command window of XP is beginning to show a new problem for us at the state of NC. I don't know if XP has anything to do with it, but Seat Management here keeps pushing software and updates on to our PC's, so can anyone guess why PKUNZIP suddenly became a problem? We have used PKUNZIP (and PKZIP) for years, but in the last month it began to show this new behavior.
In one example, PKUNZIP consistently reports CRC errors on 4 out of 49 files. FoxPro calls the PKUNZIP.EXE, but the same error occurs even if PKUNZIP is executed singularly in the XP command window.
Other clients are beginning to submit their ZIPPED files on diskette and some (not all) of these are unzipping with similar CRC errors.
It doesn't seem to be the PKZIPed files fault exactly. We can unzip and rezip the files using WinZip (a 32bit app) and the problem goes away, which tells me the complete data are in the original PKZIPed files!
I know, everyone has probably already moved all their apps from the DOS world, but please, has anyone had a similar problem? PKWARE and their tech support have moved on, and they are unable to help.
The last 16bit (2.50 ) version of PKUNZIP has the same CRC problem when extracting the test sample.
I tried pausing between files during extraction, but that makes no difference.
I've looked for a different DOS zip utility replacement, but PKWARE seems to make the only one capable archiving across multiple diskettes. The UNZIP utility created by InfoZIP doesn't produce the CRC error (on the sample file at least) but cannot create multiple diskette ZIP archives.
We distribute PKunzip as a component of an application written in FoxPro 2.5 for DOS, which will be very expensive to the state of NC to rewrite as a 32bit app. I hope someone knows what is going wrong or can suggest a solution or an automated workaround.
I could send the sample file if someone wants to take a look at the problem.
