Situation (on Mac):
Create new Montage
Go to “File properties for recording” on your recording track in montage
“Custom File Properties” is selected by default. You can name the file and it’s automatically placed in a folder in a “/private/var/folders” directory by default.
Select “record enable”
Record some files
Reload montage - all files recorded into the “/private/var/folders” directory have now disappeared with no option to recover.
I appreciate best practice is to tick “write audio file in the Montage Data Folder” before doing anything but this is not selected by default. This seems a very easy way to loose a load of work. Indeed, it happened to me today.
