Non-experienced users of a Synology DiskStation (NAS) have the possibility to use the package management option to update their system with other programs and possibilities. A special kind of package baring the extension .spk is used to do this update.
An .spk file is nothing more then a tar file, containing a standard structure and files. Every package will contain an INFO file, a compressed (gzip) tar file package.tgz and a directory scripts containing multiple shell scripts.
The file can be easily installed in the Synology DashBoard with the Package Center.
