+# MSC File Explorer (FreeRTOS)
+
+This host example implements an interactive command-line file browser for USB Mass Storage devices.
+When a USB flash drive is connected, the device is automatically mounted using FatFS and a shell-like
+CLI is presented over the board's serial console.
+
+## Features
+
+- Automatic mount/unmount of USB storage devices
+- FAT12/16/32 filesystem support via FatFS
+- Interactive CLI with command history
+- Read speed benchmarking with `dd`
+- Support for up to 4 simultaneous USB storage devices (via hub)
+
+## Supported Commands
+
+| Command | Usage              | Description                                          |
+|---------|--------------------|------------------------------------------------------|
+| help    | `help`             | Print list of available commands                     |
+| cat     | `cat <file>`       | Print file contents to the console                   |
+| cd      | `cd <dir>`         | Change current working directory                     |
+| cp      | `cp <src> <dest>`  | Copy a file                                          |
+| dd      | `dd [count]`       | Read sectors and report speed (default 1024 sectors) |
+| ls      | `ls [dir]`         | List directory contents                              |
+| pwd     | `pwd`              | Print current working directory                      |
+| mkdir   | `mkdir <dir>`      | Create a directory                                   |
+| mv      | `mv <src> <dest>`  | Rename/move a file or directory                      |
+| rm      | `rm <file>`        | Remove a file                                        |
+
+## Build
+
+Build for a specific board using CMake (see [Getting Started](https://docs.tinyusb.org/en/latest/getting_started.html)):
+
+```bash
+# Example: build for STM32F407 Discovery board
+cmake -B build -DBOARD=stm32f407disco -GNinja examples/host/msc_file_explorer_freertos
+cmake --build build
+```
+
+## Usage
+
+1. Flash the firmware to your board.
+2. Open a serial terminal (e.g. `minicom`, `screen`, `PuTTY`) at 115200 baud.
+3. Plug a USB flash drive into the board's USB host port.
+4. The device is auto-mounted and the prompt appears:
+
+```
+TinyUSB MSC File Explorer Example

+Device connected
+  Vendor  : Kingston
+  Product : DataTraveler 2.0
+  Rev     : 1.0
+  Capacity: 1.9 GB
+
+0:/> _
+```
+
+### Browsing Files
+
+```
+0:/> ls

+d----       0  photos
+d----       0  docs
+

+----a  520432  vacation.jpg
+----a  312088  family.png
+
+0:/> cat readme.txt
+Hello from USB drive!
+```
+
+### Copying and Moving Files
+
+```
+0:/> cp readme.txt backup.txt
+0:/> mv backup.txt docs/backup.txt
+```
+
+### Measuring Read Speed
+
+```
+0:/> dd
+Reading 1024 sectors...
+  Data speed: 823 KB/s
+```
+
+### Multiple Devices
+
+When using a USB hub, multiple drives are mounted as `0:`, `1:`, etc. Use the drive prefix to
+navigate between them:
+
+```
+0:/> cd 1:
+1:/> ls
+```
+
+## Testing
+
+Build-time validation follows the standard TinyUSB host example flow. Runtime behavior should be
+verified on hardware by attaching an MSC device and exercising CLI commands such as `ls`, `pwd`,
+and `dd`.
