Giant Log Viewer
Needing to check a 4.9 GB log file on a platform where the less file pager is not available? Don't cry. This software is going to save you!
This software loads instantly with same low memory footprint regardless of a 4 MB, 4 GB or 4 TB text file is opened, as long as it doesn't hit any limitation. The JVM is limited to use at most 80 MB heap memory (plus overheads) currently.
Limitations
Supports UTF-8 encoding and ASCII text files only
Doesn't work if there is a long line (>= 1 MB) in the file
Emoji sequences are not supported -- it would be displayed as multiple emoji characters
Doesn't work if your OS has no GUI
Doesn't work if you are not using Windows, macOS nor Linux
Not as powerful as less yet
