Of course you don't need to unzip to a temp file at all... I just open in WinZip with Path as the sort column, then drag and drop groups of files into the folders that I want them to be in. I get to see the whole "picture" at once as to were things have to go, and can move them easily without having to worry about vendor-named folders, etc. If I need a .pz2 to .cm2 conversion, I just drag-n-drop the files unchanged, fire up P3DO (right click on any file or folder name in Windows Explorer, it's under Send To, and it will open to the right folder) and select Tools > Pattern Renamer. Click Extension, click Replace, and enter "pz" with "cm", then click OK. It will search the entire folder, converting all that need it, and give you a confirming count of how many it changed. Simple. (You do not need to type a Filter in this case - despite what Help says.) (I would never risk installing a vendor's Zip directly into my carefully maintained Runtime! When I'm beta testing I have to of course, but not until I've done it once by hand and looked over the Zip for bugs, and then tested again in a temp directory ;-) BTW, if you prefer to see the Zip in directory nested style rather than flat, you can just use WinRAR instead of WinZip to open the .zip file. Final note: on any and all Windows systems go to Windows Explorer, Tools > Folder Options > View, then find and CLEAR "Hide file extensions for known file types", if you haven't already. Not only will that let you see .cm2, .pz2 extensions, etc., but it is essential to see past the double-extension trick used by virus creators.
