What is a .PYW file?
Plain text that programs, servers and people write every day.
A PYW file is a Python source script that runs silently on Windows, with no terminal window. It is identical to a .py file in content, but Windows opens it with pythonw.exe instead of python.exe. To open one, install Python from python.org; to edit it, any text editor works. Files from unknown sources can run malicious code invisibly, so review the script before running it.

Frequently asked questions
Is my .PYW 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.
