I'm trying to automate unzipping many .gz files on a monthly basis. Previously I used a macro a coworker wrote to do the unzipping using winzip (think he may have used some code snipits from this forum for it - seems like several sites have similar code shown in different postings). But now my office has switched over to pkware's SecureZIP, I can no longer use winzip, and my coworker has moved on. Can I manipulate that old code to work with SecureZIP somehow? I can't seem to find any suggestions on how to do this. Does anyone have any ideas or suggestions on where to start?
