If you can install software on the computer and have an Android 11 or newer phone, one way is to use the adb tool from android sdk tools to create a connection over the local wifi network which you can adb push folders over.

# Initial Setup

1. Install Android Platform Tools from: https://developer.android.com/tools/releases/platform-tools#... and verify that you can execute the adb tool.

2. Connect the Android device and the computer to the same Wi-Fi network

3. Also connect the Android device to the computer via USB cable (just for this initial setup)

4. Pair the phone with the computer and enable Wireless debugging as described here: https://developer.android.com/tools/adb#connect-to-a-device-...

# Subsequent usage (does not require USB cable):

5. Toggle the Wireless Debugging quick setting toggle to enable adb connections from your computer to your phone

6. Retrieve the Android device's IP address in Settings → About → Status.

7. On the computer command line type: adb connect ip-address-of-device:5555

8. Push the folder to the Android device: adb push /path/to/folder/to/copy/on/computer /sdcard/path/to/destination/on/android/device
