FileLocator is a PL/B independent extension of jEdit to easily load files. Therefor an index over one or more source directories is created to speed up the lookup. A filter includes only files of your interest (e.g. *.java or *.pls or *.xml).
To load a file you only need to specify parts of its filename. If this leeds to an exact match, the file is loaded, if many files match a dropdown selection list with all matching files is presented.
