parsing mmpz data?

[patchelor]

Hello,

Just wondering... how hard is it to extract/read the contents of a LMMS mmpz project file?

Is there any references anywhere for the file format?

Thanks,

It's qcompress: outfile.write( qCompress( xml.toUtf8() ) );
To get an mmp from mmpz as a user you go:
lmms --dump myproject.mmpz > myproject.mmp


I think the part, codevise, you're looking for is:

Hello.
At once I attempted to rescue my project.mmpz file this way (lmms --dump ... mmp) in Windows 10.
Seems it doesn't work. The file was created but only with header, there was no content within (length of file was 2 bytes).
lmms --upgrade...mmp doesn't work too (the message "you have no rights to read this file..." shows).
I rescued my file by more simply way (it was posted here already), but it is interesting, why one cannot simply unpack mmpz archive in Windows?

length of file was 2 bytes

That indicate that no date is saved. 2 bytes is exactly the value for those files.
I have tried to rescue projects for several users, and 2 bytes mean 'no data saved'
