File Explorer

The File Explorer shows the files and folders inside the current project.

What You Can Do

• Browse project folders and files.
• Create files and folders.
• Rename files and folders.
• Copy, paste, and drag entries within the project.
• Archive entries you no longer need.
• Add files from your computer by dragging them into Project Files in the browser or desktop app.
• Open .kcl files directly for editing.
• Open UTF-8 text files, including JSON, YAML, TOML, source files, and files without an extension.
• Reveal the project, or an individual file or folder, in the system file manager on desktop.

Open Text Files

Click a text file in Project Files to open it in the Code Editor. Edits save automatically. Text files can be up to 1 MiB. Binary files and files in other text encodings cannot be edited. Enable Show All Files in user settings to see hidden files and configuration files such as project.toml.

Text-based CAD files such as STEP or OBJ also open with a click. To import a CAD file into the model, right-click it and choose Import in current file.

Reveal in the System File Manager

Use Reveal in file explorer when you need to work with a project in Finder, File Explorer, or your platform's file manager.

To reveal the entire project, open the project menu from the project name in the Top Bar and select Reveal in file explorer. To reveal one item, right-click a file or folder in Project Files and select Reveal in file explorer.

This option is available only in the desktop app. It is hidden in the browser because browser projects do not expose the same local filesystem paths.

What You Cannot Do

• Open non-KCL files as editable KCL documents.
• Keep sketch mode active while switching files when the app needs to cancel it first.

Key Differences in This Area

• Project filesystem operations are built directly into the workspace.
• Switching files can cancel sketch mode so the modeling state stays consistent.
