Clean recent files list
I often receive PDFs but after opening them, decide not to keep them and delete them. Nevertheless, the file name still appears on the Recent File List when I say I want to open a file for editing. This makes it harder to find still existing files that I want to edit. At the minimum, be able to click on a file name on the Recent File List to highlight it and then delete that name (via Delete key or pulldown option). Even better would be to also add a option that I can click on that highlights files on the List that no longer exist and then they would all be deleted if I select Delete.
Now you can delete any selected file from Recent list with the latest releases of Acrobat DC.
Let us know if your issue gets resolved with latest releases.

Unfortunately you cannot remove multiple items easily from the Recents List. Deleting one-at-a-time is not as efficient as it could be.
While it is possible to delete multiple, that is limited to 5 as selecting more causes the "Remove..." option to disappear.
Also, each item must be clicked individually instead of being able to select a range. The viewable items is limited due to the formatting of the list. That is a lot of white-space, especially when compared to Windows File Viewer that everybody already uses.
