This dialog is small and fixed size, and the list is not sortable, so it is inconvenient when you have more than a handful of deleted items.
It isn't sorted on the file name, and it isn't sortable at all, so if your hope of finding a particular file approaches nothing as you start to get very many files in there
My related RFEs would be
#1) Make it resizable -- it is way too narrow and too short, and the solution so that it works for any resolution size is surely to make it resizable. Furthermore, as a user I want any list of files to be resizable, because sometimes long filenames occur and are illegible in narrow lists.
#2) Make it sortable. An unsorted long list is fairly painful.
#3) Split the date column into two date columns, one of file creation date and one of file deletion date, so you can look for which files were deleted close together, or you can find a bunch that were added together. Also, this clarifies what the date column means (I don't know what it means right now).
