Yil, i also have another suggestion, i personally wouldnt mind io having the option to give a valid crc32 on resumed files, at the moment, io only passes the resumed part of the file to $args, how hard would it be to precalc the crc of the already existing part of the file which is being resumed and add this to the resumed data? Did that make sense?
Come to think of it, an added itcl command to crc32 a file would be extremely nice, and would save myself using external executables for that, and how about zip too
