What is a .SAM file?
Plain text that programs, servers and people write every day.
A SAM file is a document created by Lotus Ami Pro, an early-1990s Windows word processor that is now discontinued. The most reliable free way to open it today is LibreOffice Writer, which still includes an Ami Pro import filter. A file named exactly SAM inside C:\Windows\System32\config is a different Windows system file and should not be touched.

Frequently asked questions
Is my .SAM 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.
