LST files are classified as ASCII text files. These normally contain data lists associated with the program that created the LST file. For example, certain media players use the LST file format for its playlist files, which contain ASCII text lists of media files, directory locations, metadata details and so on. On the other hand, Adobe Type Manager saves lists of fonts in a .lst file, while a few system security tools from Kaspersky and other companies use LST files to store lists of blacklisted files.Other programs that generate LST files include CAD tools like Pro/Engineer and database applications like Oracle, which use the .lst file format for its spool files. Some programs also use the .lst file format to store error logs, such as the Family Tree Maker software, which use the LST file format for its error files.The program that created the .lst file should be used to open it. However, it's best to leave these LST files alone so as for these programs to continue using these LST files properly.
