September 12, 2026 — Withdata Software announces BigTextFileViewer 3.1, a cross-platform desktop tool for opening huge text files instantly. This release adds “Go To Position”, “Pause” / “Resume” while a file is loading, new toolbar buttons, and faster reading of large files.
What’s New in BigTextFileViewer 3.1
1. Go To Position
Version 3.0 let you jump to a line number. Version 3.1 goes further: Go To Position jumps to any point in a file, in three ways:
- Byte offset — jump straight to a byte position, for example byte 1073741824.
- Percent — jump to 50% of the file without knowing its exact size.
- From the end of the file — measure backwards from the end, which is handy for reading the tail of a huge log.
The character at the target position is highlighted, so you can see at a glance where you landed.
2. Pause / Resume While Loading
Loading a very large file no longer blocks you. You can pause the loading at any time, read what has already been loaded, and resume when you are ready. This is useful when you only need the beginning of a file, or when you want to check something before the whole file is scanned.
3. New Toolbar Buttons & Faster Reading
“Go To Line” and “Go To Position” are now one click away on the toolbar. Reading performance for big files has also been improved, so large files open and scroll more smoothly.
