In the song folder I have the .cwp, the autosave.cwp, the Audio folder and a few strange temp files.
 
They're not very big and they all start with MFC but the rest is different for each file: i.e MFCBFC.tmp, MFCAJQ.temp
 
Anyone know what they are? They look like remnants of some operation that failed - just curious, I deleted them with no ill effect.
 
Thanks - rev

What time and date stamp do they have?

Never seen those before.

Aren't they just Microsoft crash dump files . . . has your project ever crashed ?

Older Cakewalk audio files look similar but have .wav extension.

That would be my guess.
I'd just delete them and carry on
 

I did just delete them and carry on. Yes my projects were crashing! I'm a Sonar 8.5.3 user (the revered version!) but I was also checking out Studio One and I needed Cubase - so I was trying to juggle 3 DAWs and all the plugs.
 
That got me into so much trouble I ended up wiping the disk. All is well.
