I have discovered a fully reproducible bug in the current (9.4) version of the Paragon NTFS driver for Linux whereby it becomes impossible to rename a folder. I am using the express version of the driver. Here is how to reproduce this bug on a fresh Ubuntu 16.04 install (tested using both Xubuntu in VirtualBox and Ubuntu on my dad's PC): 1. Mount your NTFS partition using the command: sudo mount -t ufsd /dev/sda2 /home/username/NTFS(of course, replacing the device and folder names as appropriate) 2. Change directory to the mounted drive: cd /home/username/NTFS 3. Run the following commands: mkdir test cd test ls cd .. mv test test1 The "mv" command is supposed to rename the folder "test" to "test1". Instead, you will get an error message: mv: cannot move 'test' to 'test1': No such file or directory The error only occurs after the folder's contents are displayed (e.g., running the "ls" command above). This condition can also be triggered by simply viewing the folder's contents in a graphical file manager. The error does not happen if you create a folder and then immediately rename it without viewing its contents.
