What is a .SIM file?
Plain text that programs, servers and people write every day.
A .sim file is a saved profiling session from Intel VTune Performance Analyzer. It stores performance-counter data and run conditions. Open it with Intel VTune Profiler, which is free and part of oneAPI. The .sim extension is heavily overloaded, so if your file came from The Sims or an engineering simulator, a different program made it.

Frequently asked questions
Is my .SIM 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.
