What is a .APS file?
Plain text that programs, servers and people write every day.
An APS file is an internal cache file created automatically by Microsoft Visual Studio when you edit a project's resources (dialogs, icons, menus, strings). You do not need to open it. If you found one in your project folder, Visual Studio generated it and you can safely delete it - the IDE recreates it from the .rc resource script on the next edit session. Do not commit .aps files to version control.

Frequently asked questions
Is my .APS 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.
