Getting started
Textfold is a native macOS document app, so it works the way your Mac already does.
- New document: ⌘N, or File → New.
- Open a file: ⌘O, drag a file onto the app icon, or double-click a text file in Finder.
- Save: ⌘S. Textfold also autosaves as you work and keeps Versions, so File → Revert To lets you step back in time.
- Tabs and windows: open as many documents, tabs, and windows as you like — there's no limit in the free tier. Merge windows into tabs with Window → Merge All Windows; cycle tabs with ⌃Tab.
- Rename: click the document title in the window's title bar to rename or move it, right where you are.
Encodings & line endings
The status bar at the bottom of every window shows the document's current text encoding and line-ending style at a glance.
Encodings
Textfold detects a file's encoding when it opens — UTF-8, UTF-16, Shift-JIS, GB, Big5, Latin, and more — and can convert between them. CJK text and right-to-left scripts (Arabic, Hebrew) with mixed-direction BiDi content are handled correctly out of the box.
Line endings
Files arrive with Unix (LF), Windows (CRLF), or classic Mac (CR) line endings; Textfold detects which on open and shows it in the status bar. You can convert a document from one style to another — handy when a file needs to round-trip with Windows tools.
Themes
Choose your look in Settings → General → Theme:
- System — follows your Mac's light/dark appearance automatically.
- Code Light — a crisp, high-contrast light theme.
- Code Dark — an easy-on-the-eyes dark theme.
A full theme gallery and theme editor are part of Textfold Pro, arriving across the 1.x releases.
Find & replace
Press ⌘F to open the find bar. Type to search the current document; matches highlight as you type. Switch to replace mode to substitute one match at a time or all at once.
The find bar supports full regular expressions (ICU syntax), so patterns like ^TODO:.*$ or capture-group replacements work as you'd expect. Prefer plain text? Leave regex off and search literally.
Find in Files PRO — searching and replacing across a whole folder or project — is a Pro feature, arriving across the 1.x releases.
