Norton SystemWorks was a Symantec utility suite for Microsoft Windows. The BTST file extension is associated with information files created or used by the suite.
The file stores internal information needed by Norton SystemWorks. Its specific data structure and contents are not intended for general use, and the file should normally remain in the location where the software created it.
BTST is a program-specific data format rather than a general interchange format.
Open a BTST file with the compatible Microsoft Windows installation of Norton SystemWorks. The suite may read the file automatically when required.
Do not expect a useful result from opening it in a text editor or another general-purpose application. Avoid editing or moving the file, because Norton SystemWorks may depend on it.
BTST is an internal Norton SystemWorks data file, not a document format designed for export.
If information from the file is needed, use the relevant Norton SystemWorks function to view or export it, if that function is available. Otherwise, keep the file with its original software installation.
