Getting started
Getting started
Point Texpile at the directory your .tex files already live in, and it scans for them.
- Start screen
- Open Folder…
- Menu
- File › Open folder Once you are already in a folder.
- In the editor
- Right-click a file › Set as main file In the file explorer.
- Setting
- Preferences › Autosave Preferences opens from the start screen, and from File › Preferences… once a folder is open.

Open a folder
There is no import step and no project format. Texpile opens on a start screen rather than an empty editor: choose Open Folder… and the file explorer fills with the .tex, .bib, and image files it finds. Folders you have opened before are listed under Recent, and your last folder reopens the next time you launch, on the file you left open.
New to Texpile? The start screen has a "New here? Try the tutorial" link that builds a small worked example in a folder you pick, so you have something real to edit.
The main file
A multi-file paper has one main .tex holding the preamble and \begin{document}. Texpile picks it automatically, by conventional name or by looking for \begin{document}. Right-click any file in the explorer to set it yourself. The main file is badged with a star and remembered per folder.

Two views of one file
Every file opens in either the visual editor or the source editor, and switching between them keeps your scroll position, cursor, and undo history.
Autosave
Autosave is on by default. Turn it off in Preferences and Texpile saves only when you press Ctrl+S, warning you before you switch files.
Live preview and hosting a shared session both depend on the file on disk being current, so autosave stays on while either is active.
Producing a PDF
Press Preview (or Compile, in source mode) and Texpile runs a sensible default command for you: latexmk with lualatex. It just needs a TeX distribution installed on your machine.
