The application should allow the user to select a folder using a standard dialog box, extract each zip file in that folder using WinZip, and then re-zip the new files (adding "_R" to the end of the filename to indicate that it is the re-zip). Simple enough.
Key points of this project:
1. Each zip file should be extracted to its own folder, with the same filename as the original zip file. (In other words, the "Extract to folder [path\filename]" option in the WinZip context menu.)
2. The re-zip should NOT zip the new folders themselves, but the files INSIDE the folders.
3. The new zip file should have the same filename as the original zip file, with "_R" added (no quotes, just the underscore and R) to indicate that it is a rezip.
4. It must actually unzip and re-zip the files. I know it seems like you could just add "_R" to the filename and accomplish the same thing, but for reasons that are too long to explain, that won't work.
If you have any questions, please let me know and I'll be glad to answer them. Thanks for bidding!
