I just tested this very easily, but unfortunately nothing was recorded in any of the /var/logs. The steps I used to replicate on a Lenovo P50 running Ubuntu Mate 16.04 LTS (fully updated as of 29 March 2017)
1) Open Caja 1.12.7 (also tested using Nautilus on Ubuntu 16.04 LTS) 2) Navigate to a folder that has 500 text files in it of very small size (5-10kb is sufficient) 3) Press F3 to open a new pane (or optionally open a new window, doesn't matter) and navigate to an empty folder on the same drive (or a different drive, doesn't matter) 4) Highlight most or all of the files in the source directory, and press CTRL-X (or edit > cut, doesn't matter) 5) Go to the destination pane, and press CTRL-V (or edit > paste, doesn't matter) Sometimes, the cut/paste will happen nearly instantly as it should. Sometimes though, it will take a second or two to start, then spend between 1 and 20 minutes sitting there, copying the files one-by-one, very very very very very slowly. This issue is not reproducible using the 'cp' or 'mv' command line programs. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1133477 Title: cut-n-paste move files got stuck forever To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1133477/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
