Seeking, like as in jumping to specific places in a file and taking out a specific amount of data to put together into an md5 hash? Not at all (on disk anyway). Seek "literally" moves the read pointer to a new place in the file (without reading the bytes between the old and new position). > (I'm assuming most of > these files are around 600-700mb) Mine are 1G (after processing) and 5G. There is no penalty in file size to performing an arbitrary seek into the file. > I guess we could take the beginning of the file; but is there much to > be gained from using that instead of the filename? Are people renaming > files a lot more than I do? :) Well, that is a different question, one which I share. The number of files I have renamed in terms of percentages is infinately small. b. -- Brian J. Murrell
