Include as much of the following information
Version/revision of MuseScore you are using (e.g. version 2.1)
Operating system being used (e.g. Windows 7, macOS 10.12 or Ubuntu 14.04)
If you use Windows look in Virtual drives or do a search for all created / modified files.
See: 2. Autosaved version https://musescore.org/en/node/52116
This file is broken beyond repair, it still has a valid zip header, but after that it is all zeroes.
If you last saved tzhat file with 2.0.3, if got be broken since then, it you just recently opened and saved it with 2.1, then there will be a (hidden!) backup file ".op 2 no 1.mscz,' Or there was a crash involved, you'd find some other temp backup file.
Other than the advice you've been giveb already? Take a backup you created yourself, in a different folder, on a different drive, in some cloud service or on MuseScore.com. If you don't, you should seriously consider using this in the future, for any file you don't want to risk losing.
