Powerdesigner crashed and I can't find my files. Under General Options > General I set "Save recovery backup file" to every 5 minutes but cannot find any recovery file.
In my test, I saw a directory created as C:\Users\xxx\AppData\Roaming\PowerDesigner\16.7\AutoSaveFolder\.
After shooting, and restarting PowerDesigner, I got a confirmation dialog:
---------------------------
Restore Recovery Backup File
---------------------------
A previous PowerDesigner session exited abnormally.
Do you want to restore the backup file?
---------------------------
Yes No
---------------------------
According to the documentation, this applies to "all open models". And in my test, nothing happened for a new model, until I had saved it once.
