.VSPX File Extension

A .VSPX file is a Visual Studio Performance Report Data File, created by Microsoft.

Open with Microsoft Visual Studio 2022+. Available for Windows.

What is a .VSPX file?

The file extension .VSPX stands for Visual Studio Performance Report Data File. This type of file was first used in Visual Studio 2011, a program designed for computer programmers to develop software. The .VSPX file contains important information about how well an application is performing. When developers are testing their software, they use these files to collect data on the software's performance. This data includes various performance metrics, which are measurements that show how fast and efficiently the software is running.

After collecting these metrics, the .VSPX file helps to create a summary report. This report is very useful for developers because it highlights the parts of the software that are slow or inefficient—these are often called bottlenecks. By studying the report, developers can make changes to improve how well the software works, making it faster and more efficient.

To open a .VSPX file, you need to use Microsoft Visual Studio 2022 or a later version. This is because older versions of Visual Studio do not support this file format. In fact, .VSPX files have replaced the older .VSP files that were used in previous versions of the software.

It's important to note that .VSPX files can be quite large. This size depends on how complex the application being tested is, and how much data is being collected. Because of their size, developers often save the performance reports as .VSPS files after analyzing them. This way, they don't have to recreate the entire data set from the original .VSP file, saving time and storage space.
