+"These (case sensitive) python regular expressions will filter out files during scans.<br>Directores will also have their <strong>default state</strong> set to Excluded in the Directories tab if their name happens to match one of the selected regular expressions.<br>For each file collected, two tests are performed to determine whether or not to completely ignore it:<br><li>1. Regular expressions with no path separator in them will be compared to the file name only.</li>\n"
