FileSteep is a file manager for people who spend real time in their files. Six ways to look at a folder, previews for almost anything without opening another app, a terminal in the same window, and search that finds a file by what is inside it.
Everything runs on your Mac. No account, no cloud, no folder is uploaded anywhere.
Highlights
- Six views, one folder - grid, details, gallery, column, tree and list. Switch to whichever one fits the job instead of forcing every folder into the same layout.
- Preview without opening anything - PDFs, Word documents, spreadsheets, CSV, Markdown, JSON, code with syntax highlighting, images, audio and video, all inside the window.
- Search that reads inside files - find a document by a phrase in it, not just by its name, with results as you type.
- A terminal where you already are - a full shell docked in the same window, opening in the folder you are looking at.
- Split panes and tabs - two folders side by side, drag between them, and tabs for the places you keep coming back to.
- Rename hundreds of files at once - build the pattern, see exactly what every file will be called, then apply it.
- Find what is wasting space - duplicate detection and folder size breakdowns that show where the gigabytes actually went.
- Archives handled in place - browse, extract and create zip, tar, 7z and rar without a separate utility.
- Tags, notes and bookmarks - label files your own way and jump back to the folders you live in.
- Compare files and folders - a side-by-side diff for text, and a folder comparison that shows what is missing on each side.

How it works
Open FileSteep and it starts where you would expect, in your home folder. Pick a view from the toolbar, click a file to preview it in the side panel, and press the split button when you want a second folder next to the first.
Everything else is where you would reach for it: right-click for the actions on a file, Cmd+F to search, and the terminal panel at the bottom when a command is faster than a click.
Perfect for
- Developers who want a terminal and a code preview inside the file manager
- Anyone sorting a large photo, video or document library
- People who move and rename files in bulk and want to see the result before committing
- Anyone who has run out of disk space and cannot find out why
- Anyone who finds the stock file manager too slow to work in all day
