.lst

LST is short for "list." Therefore, LST files contain lists of data. They are typically saved in text format that can be viewed in a text editor.

Numerous programs use LST files. They may be generated as log files or referenced by applications as data files. LST files that are generated as output files may be opened, viewed, and even edited by the user. However, pre-programmed LST files that are referenced by programs should not be opened or edited manually.
