Whaile (yes, like the whale) swallows files whole. The multi-gigabyte logs and text files that crash TextEdit and choke VS Code open here in about a second. The ones you'd normally only dare to touch from the terminal.
It's native on Mac, iPad and iPhone. Whaile memory-maps the file instead of loading it into RAM, so an 8 GB log opens right away and scrolls smoothly from the first line to the last. No "file too large" error, no progress bar to stare at.
WHAT IT DOES
• Opens 1 GB, 8 GB or bigger files in seconds
• Scrolls smoothly, even 50 million lines in
• Searches the whole file and highlights every match
• Jumps straight to any line number
• Barely touches your RAM: the system pages data in and out as you scroll
• Sandboxed and offline, so your files never leave your device…
