Bah !!! Got stung by the logout lose-your-post again! And this was AFTER I had reloaded the reply page and verified that I was still logged on! Different browser and did not have Lazarus Form Recovery installed. Do Now! No fun trying to recreate what I can't remember so just a few comments:

To recap what you are saying:

• Zip files created and encrypted by ZTW (internal) can be opened and decrypted by Winzip
• Zip files created and encrypted by Winzip (default) can be opened but not decrypted by ZTW (internal).
• You changed the option settings for Winzip to revert to legacy encryption methods and now ZTW (internal) will successfully decrypt the Winzip created archives.
• Winzip is backward compatible with "legacy" encryption methods

I didn't realize that there were different methods / formats for zip file encryption but that would explain why ZTW (internal) failed to decrypt the Nirsoft utility package. Even though the password was correct, ZTW said it wasn't. Had to use 7z GUI to extract the files.

What this implies is that ZTW's internal zip process needs updating. In case Kim does not read all of these comments you should post your experience as a bug report under the last ZETA release.

Namaste', Art
