My question
Hello,
Sorry about my english. It's not my native langage.
Running Duplicate Cleaner v 3.1.3, OS W7 64bits Premium. Trying to get rid of duplicates on a 2To NTFS external HD. Initial availaible space 425 Go.
Duplicate Cleaner (DC) detected the duplicates very easily. I marked about 10 Go of duplicates, wanted to delete them (without transfer to dustbin). Seemed to succeed (erased from list of duplcates), but availaible space still 425Go on my external HD.
Repeated the operation with 20 go of duplicates (had several saves on this HD)... Still 425Go free.
Rebooted, Right click on the external HD, tools => check file system...8 hours later, no problem on external HD, but still 425 Go free.
Space on the external HD does not seem to be freed

Created a "Todel" folder, and tried to eliminate a selected duplicate (.txt), with the option "move to selected directory". Failure : Security settings denied access to the source.
Impossible to run Duplicate Cleaner as administrator (will not launch with right clic menu, even though the option is availaible)... and even if I can run nearly any other program I like as administrator (I'm admin on my computer).
Any idea, please ?
Thanks in advance for your help.
Have a good day,
Sincerely
