Hi,\r\nI have XP sp3 and a 500 gig hard drive . I like to collect videos of concerts and I am up to 475 gigs on my main drive where the system also resides. 200 gigs of that are videos, the rest are MP3s.\r\nI also have a 2 TB external drive so when I saw that the main drive was almost full I moved my videos to the external drive. To my surprise XP under the c: drive properties still shows 475 gigs used....no change!\r\nThen I went into the folder of the C:drive then I selected to show hidden files and I select everything in it.After that I opened properties and the result was 278 gigs used which sounds about right.\r\nMy questions are the following:\r\n#1: Is that fixable for someone like me who doesn't have a computer science degree?\r\n#2: If I accumulate an additional 25 gigs will the computer then see the disk as full?\r\n#3: If that happens will I have problems or is there some workaround?\r\n\r\nMy system is not FAT but the other one NTFS ( is that it?) I would very much prefer if there was a way to avoid having to reinstall windows and start over.\r\nCan you guys help me?
