Option to exclude DESCRIPT.ION files (actually, %_dname). Those of us who use TCC to back up to non-NTFS devices must use the file, not the stream form of descriptions. The timestamp of these files is that of the last time a file with description was backed up, and it can dominate a recursive SIFT. A more extensive enhancement would be the full implementation of the file exclusion range. Another alternate to achieve the same basic goal (but which may falsify the results too much) would be an option to ignore hidden files.
