On the first one, this is a "bug" that's existed since at least Windows95. Basically Windows only remembers a set number of folder preferences. You can increase this number, but that in turn will require more RAM and processing time.
On the second one... Since you admit to pirating stuff via P2P, it would be against forum policy to assist you.
I am fairly adept at using computers but these 2 minor, fiddly issues have me stumped.
Using Windows XP.
I use Windows Classic Format to view all my folders. I then format the subfolders ( and their subfolders) to view Thumbnails or Lists etc. and I cascade my folders and set the viewing size. However, if for example, I change the name of a folder or move it, all the subfolders revert back to default settings and I have to reset them all again. How can I get them to stay as I set them?
Second, I sometimes have trouble deleting some media files. The error message states that 'file can not be deleted as another program is using the file - close this program and try again'. I have closed all other programs including P2P etc but I keep getting the same error. It only occurs on some files, not all, I have copied the file and the copy will delete. I have tried changing the format or renaming but nothing works.
