Map Cloud Drives to Local Disk Using RaiDrive
RaiDrive is an open-source cloud drive mapping tool that supports Google Drive, Google Photos, Dropbox, OneDrive, FTP, SFTP, and WebDAV. Currently, the tool is only available for Windows.

Download and Installation
You can download the latest version from the official website https://www.raidrive.com/download/ and install it.
Connect Cloud Drive and Map
RaiDrive supports a Chinese interface and is very easy to use. This article uses Google Photos as an example. Due to well-known reasons, Google services cannot be accessed in China, so please prepare a proxy service. Then go to Settings - Set HTTP Proxy - set the proxy to 127.0.0.1:1080 as shown in the screenshot below.

Click the Add button in the upper right corner, select Google Photos, and do not forget to check the "Proxy" option.

This will automatically open a browser to redirect to the web authorization page. Complete the authorization as prompted, as shown in the screenshot below.

After authorization is completed, you will see the following prompt, indicating that the mount was successful.

Return to the RaiDrive interface to see the mounted cloud drive. If you need to mount other cloud drives, the method is similar.

Summary
RaiDrive currently only supports the Windows system and is simple to use. Another similar tool is Rclone, which supports more cloud drives and can be mounted to servers, but it does not have a graphical interface.
