What is LST file?

The .LST file is a text file. It contains a list of data where various things can be understood as data. Generally, the content of the list is irrelevant as long as it can be saved in text format. Line breaks are used as separators. Files of this type are quite often used in installers or when exporting files. They serve as a checklist to verify that all files are present. Binary structured .LST files can happen occasionally, but this is a very rare case.

How to open LST file?

The most common problem when using Data List is that a specific LST is not associated with the program. This causes the file LST to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the LST file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install TextEdit

An often overlooked issue is to make sure that TextEdit is installed on the computer. This can be achieved by typing TextEdit into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file LST.

Step 2. Create association of TextEdit with LST files

However, it may happen that the application itself does not cause the LST file to open in the TextEdit application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the LST file with the TextEdit program.

Step 3. Update TextEdit to the latest version

The fault may also lie with the TextEdit program, it is possible that Data List requires a newer version of the program. In this case, use the Apple, Inc. website or update the program from the application.

Step 4. Check for the following problems with the LST file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The LST file may be unusually small compared to the original file. Usually this applies to LST files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the LST file that we want to open. Sometimes virus-infected LST files cannot be recovered, so make a backup in advance.
Older version of LST file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged LST files. You can restore the file from a backup or use N/A help.
The program indicates that the file is encrypted or corrupted. The encrypted LST files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. Copying the LST file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the LST file again. However, some background programs may block the LST file while scanning. If the problem persists, restart the machine.
