The complexity depends on the total size of the data. A big file is worse than a small directory. Mael> But the first question to answer is: do we need it?? I think we do, but I do not remember whiy it is better than our old time-base version. One advantage is that you detect when a file has been updated without change: typical of the .aux file written by LaTeX. Mael> Further, if we need it for files, do we need it for directories? Yes if we want directories to masquerade as files. It should be possible to feed in order all the bytes of all the files in the directory to the crc checker. If we have a proper directory iterator in boost, it should be fairly easy. JMarc
