I tried to download some movies last night. I used AVI previewer to preview the movies but there were no playbacks. Moreover, whenever I used AVI previewer, my free space in the C drive decreased (my shared folder is in D drive) and it remained unchanged even if I refreshed the screen. I had checked the free space in all the drives using Defragment. They are correctly listed over there. So what is wrong with the indicator of the free space in My Computer? I would appreciate if anyone can help me with this. Thank you.
