There is only one file type that uses the .VSPROPS extension:
Visual Studio Project Property File
Property sheet file created by Microsoft Visual Studio 2008 and earlier; stored in an XML format and contains build properties and user-defined macros for a project; used for exporting and importing common settings between projects.
To create a project property sheet, open Visual Studio and select View → Property Manager, which displays the Property Manager pane. Right-click the target project in the Property Manager and select "Add New Project Property Sheet."
NOTE: As of Visual Studio 2010, property sheets are stored in .PROPS files. When upgrading projects to Visual Studio 2010, the software automatically converts VSPROP files to PROP files. However, there may be small conversion incompatibilities with special characters in macros.
