File Browser

The File Browser lets you navigate the computer’s filesystem to locate the files you need for a task — data files, source code, workspace archives.

Click any file of a supported type and its content appears in the central tab widget for a quick preview without fully opening it. Supported types include .xlsx, .txt, and most source-code / script files. Toggle this behavior with the Preview Item option.

Filter visible entries by typing keywords in the Filter text box at the top of the window — same affordance as every other tool window. The filter respects the Case Sensitive, Use Wild Card, and Use Regular Expression options described below.

Three toolbar actions for filesystem navigation are available directly on the toolbar:

  • Sync Active File — scrolls the tree to ensure the file in the active document tab is visible and selected.
  • Collapse All / Expand All — collapse or expand every folder node in the visible tree.

A drop-down on the navigation toolbar with shortcut destinations:

  • Go Home — navigate to the user’s home directory.
  • Go to Root — navigate to the system root.
  • Go to CWD — navigate to the current working directory of the active interpreter (default action of the Goto button).
  • Set as CWD — set the currently selected folder as the active interpreter’s working directory.

The Preferences (gear) drop-down at the top-right of the window groups the file-browser options.

When enabled, single-clicking a file of a supported type previews it in the central tab. On by default.

Three checkable filter modes that restrict which files are visible. They can be combined.

  • Supported Type Filter — show only files of types MathJet can open (data files, source files, workspaces, etc.).
  • Open File Filter — show only files that are currently open in the program.
  • Pending Change Filter — show only files that have unsaved modifications.

Control how the Filter text box at the top of the window is interpreted:

  • Case Sensitive — match case when sorting and filtering.
  • Use Wild Card — interpret * and ? in the filter expression as wild cards.
  • Use Regular Expression — interpret the filter expression as a regular expression.

Show hidden files (dotfiles on POSIX, hidden-attribute files on Windows) in the tree. Off by default.

Render alternating rows with subtly different backgrounds for easier readability of long file lists.

Control which detail columns appear next to the file name in the tree:

  • File size
  • File type
  • Date modified

Each is independently toggleable.

  • Data Source Window — for working with files that are already open as data sources.
  • Workspace Manager — for navigating the in-memory object tree, separate from the on-disk filesystem.
