What is the __MACOSX folder?
The __MACOSX folder is created when a Mac user creates and archive (also called a zip file) using the Mac. If the Mac user sends the zip file to another Mac user, the folder will not appear - this is a hidden folder. Many files on the Mac have two parts: a data fork, and a resource fork. The built in zip utility on the Mac sequesters all of the resource forks into this __MACOSX folder when creating a zip archive. For certain files (like some font files), these resource forks are necessary to be left intact. ZipFiles4PC also has an option to preserve the resrouce forks without creating the __MACOSX folder.
When the Mac user sends the zip file to a PC user, however, all of the hidden files are shown. PC users are often confused by these (seemingly superfluous) files and folders. You can use our Zip Files for the PC utility to create zip files that contain neither the __MACOSX folder, nor the .DS_store files!
