Whilst the question is argumentative, you have to understand their frustration.
I assume we are talking about actual project assets and not gameObjects, since you can undo deleting them? In which case I agree its far too easy to accidentally project assets and not always clear what you are deleting.
However, I think assets end up in the recycle/waste bin, so can be rescued. At least when I checked on this a few days ago it appeared Unity moved scripts there, so might be worth checking?
It doesn't help that you have to use the delete key to delete project assets (it should also be in the right click menu for the project panel), making accidental deletion even more likely. Of course it brings up a dialog box, but it doesn't actually tell you what asset it is about to deleted.
Although its always prudent to have a back up system, suggestion source control is hardly an answer for something that could be improved within Unity itself.
Try using source control. Checkin frequently, update frequently, and you can avoid this problem in the future. It also prevents data loss in the case of hard drive failure and force majeure.
I wanted to rename a Project View folder from "jwh" to "Jwh" (Change the first letter to uppercase)
I wasn't able to do this in the Editor.
I deleted the folder and recreated it with the uppercase letter in
unity editor.
I though I had the file open in my editor incase it got deleted but I didn't.
Now I can't find it anywhere.
