What is a .msp file?
A .msp file is an unknown. Its registered MIME type is application/octet-stream, which places it in the application or document family of formats.
MSP is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.
The same format is also saved with the extensions .bin, .bpk, .buffer, .deb, .deploy, .dist.
