Hi, I know this one is not your main product and you've not updated it in some time but in case you want to know I came across an error yesterday. I wish I had a debug build of the program or at least a version which created logs anywhere to give you a more detailed description: Operating system: Windows 7 Professional (32-bits), but I'm pretty sure it would happen in a Vista environment as well. Filesystem the file was in is: NTFS 3.01. Streams of the file: 1, just the primary, no ADS. Misc. info: The file was a hard link to another file my user owns both. User info: Full privileges (and UAC is disabled). OK, so when selecting to delete the file from the GUI using the options: "Unlock locked file handles", "Unload modules", "Terminate the file's process" and "Delete file" causes the program to exit. Executing the CLI using the parameter /assassinate gives the following info: FindRemoteFileHandles returned NULL value. Thank you very much for your time and congratulations for such good programs, James Russell.
