Q-Dir — View Four Folders in One Window, No More Switching Back and Forth
In one sentence: Windows’ built-in File Explorer can only show one folder at a time. Q-Dir can show four.
Driven Crazy by Multiple Folder Windows?
Your boss asks you to organize contracts from folder A into folder B, referring to folder C for format templates, and finally move the finished work to folder D for archiving. You open four File Explorer windows, click back and forth on the taskbar, drag files while windows overlap, and accidentally drop them in the wrong folder.
Windows File Explorer’s core interaction hasn’t changed since 1995 — one window shows one folder. When you need to work across folders, you’re stuck managing multiple windows.
Q-Dir completely overturns this outdated logic. It packs four independent file panels into a single window, each one a fully functional File Explorer. Arrange them however you want — horizontal, vertical, grid — switch with a click.
Why Is Q-Dir Better Than the Built-in File Explorer?
1. Four-Panel Layout, Drag-and-Drop Copying
Open Q-Dir and you see four panels neatly arranged by default. Top-left, top-right, bottom-left, bottom-right — each panel navigates independently to different folders. Drag a file from panel A to panel B to copy it. Hold Shift while dragging to move. Hold Ctrl while dragging to create a shortcut. All operations happen in the same window — no switching screens, no shuffling windows around.
2. Seven Panel Layouts — Switch With One Click
Not everyone likes the four-grid layout. Q-Dir offers 7 preset layouts, switchable with one click on the toolbar:
- Four-grid (default, most common)
- Two horizontal (great for widescreens, side-by-side comparison)
- Two vertical (portrait orientation, top-bottom comparison)
- Three panels (one main + two reference)
- Single panel (traditional File Explorer)
3. Synchronized Browsing — The Killer Feature for Folder Comparison
This feature alone might make you love Q-Dir. With synchronized browsing enabled, when you double-click into a subfolder in panel A, panel B automatically navigates to the same subfolder. Use it to compare backup directories between two computers, compare historical versions of project files — whether folder structures match is immediately obvious.
4. Each Panel Independently Remembers Paths
Those few folders you visit all the time — downloads, project documents,素材 library, archive folder — pin them to the four panels and save the layout as a .qdr file. Every time you open Q-Dir, it restores directly to your last working state. No need to navigate again.
5. Global Bookmarks and Color Coding
Cross-panel shared bookmarks — drag a commonly used path from bookmarks to any panel to open it. Each panel can also have a different title bar color. Four panels in four colors — no confusion during operation.
6. Under 5MB, USB Plug-and-Play
Q-Dir’s portable version is only 3-5MB. Extract it to a USB drive and use it on any computer. It doesn’t write to the registry or create system files — plug in and use, remove without a trace. Company computer won’t let you install software? Q-Dir portable solves the problem.

FAQ
Q: Can Q-Dir replace Windows’ built-in File Explorer? Yes, but requires manual setup. In Options → System Integration, check “Replace Explorer.” Then double-clicking “This PC” on the desktop will open with Q-Dir.
Q: What’s the difference between portable and installed versions? No functional difference. The portable version stores all config in .ini files in the program directory, suitable for USB drives across multiple computers. The installed version stores config in the user directory, suitable for use on a fixed computer.
Q: How do I enable synchronized browsing? Click the “Sync” button on the toolbar (the icon with arrows between two panels). Once enabled, when one panel switches folders, the other follows.
Q-Dir takes four File Explorers and combines them into one — but after using it, you realize file management was always meant to be this simple.
