Opening XST files

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

What is a XST file?

Files that contain the .xst file extension are most commonly associated with the WebSphere Application Server.

WebSphere is a server program that hosts different Web applications. The XST files are XML-formatted files that contain database connection information, an SQL query and an SQL to XML Java class. The file is used to generate XML data from an SQL database query.

The Tanner Ledit software application also uses the .xst file suffix. These XST files contain crossview data files that are referenced by the Tanner Ledit program.

The Microsoft Outlook POP3 email and calendar application also uses the .xst file suffix. These XST files contain a user's personal folder files that are used within the Outlook program.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
