What is a .VSPF file?
Plain text that programs, servers and people write every day.
A .VSPF file is a Visual Studio Performance Filter File used by Microsoft developers. This text-based format contains specific criteria for filtering performance data within the Visual Studio environment. These files are primarily accessed and managed using the Visual Studio software suite.

Frequently asked questions
Is my .VSPF file uploaded anywhere?
No. The file is read and highlighted for you.
Why do some characters look wrong (é, ł)?
That usually means the file was saved in one encoding and opened in another. We detect UTF-8, UTF-16 and the Windows-1250/1252 code pages automatically and show which one was used.
Can it handle huge log files?
Yes, up to 50 MB. Only the lines on screen are drawn, so scrolling stays smooth. Syntax colours are switched off for files over 1.5 MB to keep things fast.
How do the log level filters work?
We find levels like ERROR, WARN, INFO and DEBUG on each line. Lines without a level, such as stack traces, stay with the entry above them, so filtering to errors keeps the full trace.
Can I edit the file?
This is a viewer. To change code, download it or copy it into your editor. Converting encodings and line endings is planned.
