What is a 1ST file?

Files that contain the .1st file extension are most commonly used for the "Read Me" files that are associated with a variety of different software applications. When a user downloads a software product from the Internet, the download usually includes an associated “Read Me” file. This file contains information about the installation and use of the software product. Read Me files are often saved in a plain-text format with the .1st file extension.

The .1st file extension is also used for documenting wizards lists that are used by the Visual FoxPro software development program. This program is a data-centric, object-oriented programming product distributed by Microsoft.
