Hi George - Yes, as Mark suggests, that was me.
I use a “wrapper” that first deletes the database (plus thumbnails & cache) and then invokes PL … I do so because I’d rather depend on sidecar/.dop files than risk database corruption (plus, I have no interest in any of the database-specific features; DAM, Projects, History, etc)
Here it is, in Win10 CMD format (I compile this to an EXE): Invoke_PL50(ClrDB+Cache).zip (401 Bytes)
CAUTION: Running this (on a Win10 machine) will delete your PLv5 database.
