A vspx file extension is related to Microsoft Visual Studio. VSPX files store data for internal purposes of Visual Studio. The vspx file type can’t be converted to other formats. This is usually the case for system, configuration, and data files used by specific software.
You may need to update the application you use to open .VSPX files. Only the latest version supports the current format. You should also scan the file for viruses with antivirus software.
If Windows doesn’t recognize the .vspx extension, you’ll get an error when trying to open the file. Windows needs a default app associated with the file type.
VSPX files can get very large depending on application resource needs. Developers often save analyzed reports (.VSPS files) so they don’t have to regenerate data. VSPX files replace older .VSP files used by previous Visual Studio versions.
To open a VSPX file, check your system has resources to run Visual Studio. Also check the file copied completely. If incomplete, re-download the VSPX file. If still unable to open, contact an IT expert.
