File type specification:
The pzx file extension is associated with the Perfect ZX tape format used by some ZX Spectrum emulators.
The pzx file format is a generic file format that can store either standard tape loading blocks as well as custom- and turbo loading blocks.
The format has been structured so that it would be easy to implement new block types as well as custom data. PZX files are supported by newer ZX-Spectrum emulators.
PZX files are simply concatenated blocks that are indicated and introduced by a 4-byte string. They always must begin with a PZXT block, but this block also may appear several times within the file.
This pzx file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
