The backup file generated by the Plesk Backup utility is a multi-part mime-encoded file. In other words, it is not a simple archive file that can be "unzipped" to access its contents. The format of this backup file is encoded by the Plesk backup utility and cannot be accessed directly in an elegant way.
Each component within the file is for a specific purpose or location. There are individual areas for the configuration files, databases, SSL certificates, mail, and websites. The backup file is useful if you wish to restore an entire site or server through the Plesk interface. However, if you need only a specific directory, database, or a selection of files, you will need to get a little creative.

There are a few workarounds for manually accessing the file.
- Plesk has an outline on a few advanced methods in an article from their Knowledge Base.
- If you are on a Mac, the third-party "Stuffit" application is capable of reading these files. They offer a free version with basic functionality. There is a Windows version of Stuffit as well, however, it does not provide the same functionality.
