    I have a download folder where I keep all my downloads which includes a lot rars & pars.

    Would it be possible to add an option to tell QuickPAR not to scan through all the PAR files unless the filename is similar.

    example:
    happy.part1.rar
    happy.part2.rar
    happy.part3.rar
    happy.par2

    and not scan 1231283019283.par2

      In particular, the files that should be scanned first are those that differ only by whitespace: space & underline.

      QuickPar's file scanning procedure is as follows:

      1) Files whose names are the same as or very similar to the target data files are fully scanned.

      If (and only if) there are damaged or missing files and there is insufficient data for repair:

      2) All other files in the folder are quickly checked to see if they are renamed versions of the target data files.

      The quick check that is carried out when looking for missnamed files uses the following procedure:

      1) If the size of the file does not match one of the target files no further processing is done.

      2) The first 16k of the file is read and the md5 hash computed. If that does not match one of the target files then no further processing is done.

      3) The complete file hash is computed. If that matches one of the target data files then it is listed as a missnamed file.

      This overall procedure should be fairly quick. On my computer in a folder with over 8000 files it takes about 5 seconds.
