You can expand the storage on your Xiaomi Redmi Note 3 by as much as 256GB if you install a microSD card. However, recording 1080p videos and taking high-quality photos may use up this storage capacity very quickly. Adding a bunch of audio files to your Library also drains the precious gigabytes.

To avoid running out of memory on your Xiaomi Redmi Note 3, you should regularly transfer the files to your computer. These are the steps that you need to take:
Enable USB Debugging
You need to enable the USB Debugging mode before you can transfer files from your Xiaomi Redmi Note 3 to a PC. Also, you need to make sure you have the latest MIUI Version of the software in the About Phone menu.
This is how to enable USB debugging:
1. Launch the Settings App
In Settings, swipe down until you reach Additional Settings and tap to enter the menu.
2. Select Developer Options
In Additional Settings, find Developer Options and tap to access more options.
3. Toggle on USB Debugging
Tap on the switch next to USB Debugging to enable it.
4. Confirm Your Selection
A pop-up window will appear asking you to confirm. You should tap OK to enable the USB debugging mode. This mode allows you to easily copy data to your computer. But you should know that it also allows apps to be installed without a notification and it reads your log data.
Now you can connect your Xiaomi Redmi Note 3 to your PC via a USB cable and transfer files using Windows File Explorer. But you can also do it wirelessly as outlined below.
Transfer Files to a PC Using FTP
File Transfer Protocol, or FTP, is a feature that enables you to move files from one host to another through the Internet. You don’t have to use a USB cable for FTP file transfer. However, you need to have a stable internet connection to avoid losing or damaging your files.
These are the steps that you need to take to move files to a PC using FTP:
1. Connect to Wifi
Both your computer and your Xiaomi Redmi Note 3 need to be connected to the same hotspot or router.
2. Launch File Explorer
Enter the Explorer app on your smartphone then tap on FTP to initiate the process.
3. Tap on Start Server
Once you’re inside the FTP menu, tap on Start Server to turn your phone into a mini server. Then choose the storage volume that you wish to access via FTP.
4. Select Your FTP address
When the server starts running, your FTP address will appear on the screen.
5. Launch Windows File Explorer
Click to open File Explorer on your PC and enter the same FTP address in the bar. Alternately, you can enter the FTP address in your browser.
6. Select the Files that You Wish to Transfer
After you’ve entered the FTP address, you will be able to access all of the files on your Xiaomi Redmi Note 3. Choose the relevant files and copy them to the desired destination on your computer.
The Final Transfer
Moving files from your Xiaomi Redmi Note 3 is not as hard as it may seem right off the bat. Once you enable USB debugging or get comfortable with FTP transfers, it’ll be easy to move files to the desired destination on your computer.
However, if you want to have more options while transferring your files, you can check out some specialized third-party apps in the Play Store.
