Here it's probably because your file.avi is mostly full of zero which will not be stored in a filesystem with "sparse" support (like ext3). Most modern technologies (especially P2P, like bittorrent) use this capability. Check for the "sparse" keyword in the manual pages of "cp", "tar" or "rsync". -- Jean Christophe "????" ANDR? ?
