Usually you need the program Packager MK1 for restoring files. But if you want to pass archives to anyone who doesn't have Packager MK1, it is adviseable to create selfextracting archives.

Along with the partition of the archives you can choose the option "selfextracting archive" through a click at the corresponding button (1). The first archive becomes an autonomous running program, which is able to restore files without using Packager MK1.
