Apologies for the double comment - but I realized I missed one of your questions. The size and type of files does not seem to matter. I've had this happen with text, image, video, and "other" files of sizes from a couple kilobytes up to several megabytes. I have not tested with a large number of files of several gigabytes, though I don't imagine it would be as noticeable since one would reasonably expect those to take a bit of time to copy normally.
As far as I can tell there are no definite triggers. When I was first doing a prototype build of Ubuntu 16.04 LTS and ran into this bug, I did a fresh build, updated all packages, and then was able to easily replicate after a clean boot and nothing running except the file browser. My current system uses SSD drives only, but I have also verified on a system with spindle disks. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1133477 Title: cut-n-paste move files got stuck forever Status in nautilus package in Ubuntu: Incomplete Status in pcmanfm package in Ubuntu: Incomplete Bug description: With Nautilus, I navigated to a folder that contained about 2,000 gif files. I selected all of them I cut with Ctrl+X I navigated to another folder I pasted with Ctrl+V => A popup window appeared saying "Preparing to move N files", and it got stuck there forever. Nautilus stopped responding. I waited half an hour, then I had to kill it. Actually some of the files were moved. Which is the worst thing that could happen. I tried again with the remaining files and it happened again!! It's systematic!!!!!! I suspect it has to do with displaying the previews of a big number of files. Nautilus becomes completely unmanageable whenever you open folders with lots of files. Maximum priority should be given to the UI and actual operations; displaying of the previews should be done in the background and should never, ever slow down user operations the slightest bit. Seems pretty obvious. Also note that 2000 is not even that much. Actually it's very few files.
