When I said "and store this new file name in a field in your file manager." I was attempting to address this issue. The lack of a PK is certainly a hurdle. There could be a new table that only has deleted records in it--it would have original file name (with full path, I suppose), and the new file name in the TrashCan. With no PK, there has to be something unique to identify each entry...

And I like Ed's idea of compressing the trashCan (I think he is suggesting a longer term archive).
