I have 3 HD's running. Two (NTFS) internal and one (FAT32) external. A 300GB (NTFS) with about 14GB of free space. A 60GB (NTFS) with 9GB of free space. A 160GB (FAT32) with 149GB of free space. I am getting this error message while trying to transfer a 4GB Movie from the 300GB HD to the 160GB HD saying "Error copying file or folder, There is not enough free disk space". Obviously there is enough disk space on the target drive for the movie but for some reason or another it doesn't think so. Windows also recognizes that there is the correct amount of space available, it only says there isn't when I try to transfer. I tested transferring with other files and it works fine, its just that file. I also tried transferring it to the 60GB HD and it worked without any problems. My questions are: Is there something wrong with the file? Is it that there isn't enough room in a temporary folder for it to transfer a file that big? Is it the fact that they are different file systems? Is there something wrong with my HD? Or is it something that i'm not thinking of? Thanks for your help. Sorry if this post is in the wrong section, I thought it was the most appropriate.
