With Ubuntu 18.04, I can drag and drop files from Desktop to File manager and vice versa.
On my other Ubuntu 20.04 install, this is no more possible.
Has this fetaure been voluntarily removed or is it an accidental regression?
How to enable it again?
Many people seem to have noticed the same problem, see for example the 100+ voted comment about this on the video Ubuntu 20.04 LTS: What's New?: "Love Ubuntu, but I'm still disappointed a basic feature like drag & dropping files to/from desktop into the file manager is missing.".
Note: This is strange for a LTS; why did they accept this a-little-bit-broken state for a Release version, did they consider it's not important? All major OS support drag n drop out-of-the-box from/to Desktop since Win 95 probably. (Without having to tweak some parameters). Do you think there's a hope to have this solved in 20.04.1 or 20.04.2?
Files
windows, one open to the Desktop, and the other open to where your file is, you can drag the file icon between the two open windows. – heynnema Jun 26 '20 at 16:58
