Last week I updated the firmware on my QNAP TS-210 NAS running the latest version of Twonky Media Server. After doing so, I found that as well as my existing music, I also had 5 'samples', which were stored in a folder called 'samples' in QMultimedia. Not wanting these samples, I deleted the folder, but they are still present somewhere on the NAS.
I can see the files in Windows Media Player, but can't delete them. I cannot see them in any Windows search, in any web browser, or in Mp3Tag. I cannot find them if I open a DOS Window, and look for them there.
