Comment 31 for bug 51043

"don't exactly know what you mean with "space in dest folder is full" - disk space? no, please explain."

Of course he isn't talking about disk space. Is it so difficult to understand? What he means:
In List View each row contains one file. Let's say, there's enough room in the window to fit 40 rows in it (so 40 files can fit in this window).

Now you copy a file and you try to paste it in the destination foler. If the destination folder contains less than 40 files, there are some empty rows left, so you can use this empty space to paste the file. If the destination folder contains 40 files or more than 40 files, there's no more space left to do a secundairy click to be able to paste the file, so the "destination folder is full" (not in terms of available bytes, but number of empty rows a.k.a. whitespace).

"in Dolphin/Konqueror you can right-click on the whitespace right to the file names in detail view or anywhere in between the files in the symbols view, and choose "Paste", when you right-click on a folder, you can choose "paste into folder".
IMO this is the way nautilus should do it as well"

I also did a test and you're completely right. This is the way Nautilus should work. This is the way all file managers (except Nautilus) work.
