The material which appears here will one day be distributed with USBSink as Yelp-browseable help. If you want to see more information here, submit a bug (see the development page), or post on the mailing list.
When creating a new task, you can specify which files USBSink should ignore by creating a file ignore list or entering regular expressions separated by a new line. File ignore lists are files located in ~/.usbsink/ignore-lists and contain regular expressions, and as such are a convenient way of keeping and reusing similar groups of them. See ~/.usbsink/ignore-lists/common for an example. USBSink can understand Perl-compatible regular expressions. For a reference, the perlre manpage is very good, and usually always available.
For example, if you'd want to skip all .log files, you'd write:
.*\.log
Or, to skip all mp3 files that start with two digits:
(\d\d).*\.mp3
