|Not sure how you're trying to do it, but if you select any one file, then use Ctrl-A, it should select all files. Next drag any one and all should follow. Another way to select is to left click on first file, then Shift click on last one. Then drag the entire lot to your new folder. I know it's tricky using My Computer (I never use it! I use Total Commander), but it should work.|
Don't squat with your spurs on!
