How to check if 5000 items who are removed have to stay?

Did you look at www.dropbox.com/events ?

Thank you for your advice.

But on Events I can scroll through my 4000 deleted items, without seeing them. I can see and restore them only one by one. Is there another way of seeing/judging and eventually replacing more items at once?

Hey Marjan10,

Unfortunately, when a file is deleted, you can't see a preview of it, before restoring it.

As a workaround, you could use the Rewind option to restore all the deletions and then see/review and delete the files you don't want to keep.
