Opening 1ST files

Did your computer fail to open a 1ST file? We explain what 1ST files are and recommend software that we know can open or convert your 1ST files.

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.
