Notes about the Z09 file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The Z09 file type is primarily associated with 'WinRAR' by RARLAB.
Z09 is usually the tenth compressed file in a series, preceded by Z08.
The Z Archive System is a set of programs used to compress, extract and view files and folders on Unix-based systems. It is self-extracting meaning data can be extracted by executing the folder itself.
WinRAR for Windows is able to uncompress Z Archive files.
