Selecting Specific Files

I think it would be beneficial if I can select specific files to move or download rather than only the option to select one file or all files. In many cases I have 50 plus files on a specific item and only need to download a few dozen or in some cases move a few at a time to a dropbox or google drive folder. I would like the flexibility to select certain files that I would then like to, “download”, “move to”, or “delete”. Please advise.

Definitely necessary.
I have automations that create files, so there can be many, and at times a bulk delete is needed. Multi-select checkboxes, including “Select All”, would help a lot.
