Cloud drive service brings us a lot of convenience (for example, access to and download files anytime and anywhere, save a mass of local disk space, own almost unlimited cloud disk accounts to get an unlimited expansion of web disk space), but it is cumbersome and inefficient to upload and download files without a desktop client and only using the web browser. As a result, often in order to manage your files in the cloud, you had to download a bunch of different software (official client), even for different services you have to repeat this step.
