The Filter feature allows you to filter the files you are interested in by viewing in the directory tree display. You can filter by the condition of files, file names, file dates, and file sizes.

If you are looking for files with a specific name, you can enter a file filter string, either with or without using 'wildcards'. If you are looking for files with a specific type, several popular file groups are listed in the pull-down menu for you to choose from. You can always add to a file group by selecting the group and adding a new type to the string with "," symbol (e.g., *.doc, *.xyz).

Also, you can filter files based on file sizes in bytes, file dates and file conditions.
