I have a Sony Camera. I had some videos in it. To backup the same I copied them in my computer. It is a Windows Vista PC. Now everything went well. The data was around 1.5GB which copied well. I created a DVD out of those Videos. All files are kept on my desktop inside a folder. Now when I try to delete those files my PC freezes. I have to restart that forcefully. It does not respond at all. The same things happen when I right click on the files to view the size. I do not understand why this is happening. Things were working quiet fine last week, but the time I had used the camera it started giving me problem. When open the folder, the green bar which keeps on moving very slowly at the top. It does not completes. I had tried a number of things to make it work, but nothing happens. What should I do to get rid of this files.
