What it is

A portable session file. A .mfproj is a zip archive that bundles the source audio (32-bit float WAV at the original sample rate), every DSP setting in the chain, surgical cuts, gain edits, edit history markers, the loaded reference track, and Match EQ tags. One file, reopens any time, continues exactly where you left off.

How to use it

What it affects

For multi-session masters, save / load is the difference between continuing and recreating a chain. The .mfproj is also a clean way to archive a finished master with the exact settings that produced it, or to hand a session over to someone else. Surgical cuts are baked into the saved audio (the file is exactly what you heard), and the cut markers come back in the History panel after restore.
