Notes about the PIZ 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 PIZ file type is primarily associated with 'Renamed Zip File'. In order to get around some E-mail attachment blockers tuned to block out the .ZIP file extension some have taken to renaming the file with a .PIZ extension (.ZIP backwards). Use any unzipping utility after renaming the file. Look at the file in an editor (do NOT save the file from the editor) and see if it has the characteristic PK characters as the first characters in the file to confirm the file is really a ZIP file.
