Does DynaZip skip open files? Someone said so a few years back so I never looked at it again.

WINZip protects me in this critical area. So I just paid for it and its done. What do you do for backups in 24x7 environments? Kick everyone off?

The functionality to extract compressed files is also available through the Win32 SETUP API. You can call the DOS command line utility EXTRACT the same way you'd call PKUNZIP, via RUN or CreateProcess(); EXTRACT /? will list the command line parameters available for it.

>If you really need to compress data for other than data, you might consider putting the data on an NTFS volume and enabling NTFS compression tranmission purposes (IOW, store the data on a routine basis compressed by the NT operating system; I do not recommend using Novell's compression because of problems I've seen with some Novell Client software and compressed volumes). I've never been an advocate of any of the DriveSpace family of tools for Win9x, but they also can do on the fly compression and decompression without any special programming.
