Configure

This step is used for selecting multiple files and providing them as a list of filenames. Use the Add button to choose a directory to select files from. Use the Remove button to remove selected files. Use the Remove ALL button to remove all files listed.

The Add button opens a directory chooser dialog. Once a directory is chosen the Fig. 81 is shown to choose which files to load from the directory.

The Load directory files dialog has a file filters input where basic regular expressions can be entered to filter the files that are to be added. For example, *.py will filter all files ending in .py, commonly Python files. The Load directory files is aggressive, in that it will recurse into sub-directories to find files that match the filter expression. If no filter expression is entered, then all files found in the directory and sub-directories will be added.
