WinRar diagnostic message..."There is not enough space on the disk. Only NTFS file system supports files larger than 4GB Is the message that I keep getting when I try to unzip ISO files. I have heard that I can change my drive format in the command prompt by typing convert [drive letter]/fs:ntfs however I am worried that this might affect me later because I hear it is a one way street. Is there any reason why I shouldnt do this or any reason why Fat32 is preferable over NTFS?
