Notes about the MSCZ 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 MSCZ file type is primarily associated with 'MuseScore' by MuseScore. MSCZ is the standard MuseScore file format and recommended for most uses. A score saved in this format takes up very little disk space but preserves all the necessary information. The format is a ZIP-compressed version of .mscx files and includes images. MSCX is the uncompressed version of the MuseScore file format used in version 0.9.5 or later. A score saved in this format will not lose any information except images and is recommended if you need to manually edit the file format using a text editor.
