Diino accounts come in many varieties, only one of which is free, with a capacity of 2GB, which is already quite large. Diino provides users with a local client software, and every time you upload or back up files, you need to use this client. It seems there are no other restrictions; individual files have no size limits, so you can upload files or folders. However, perhaps because Diino is an overseas service, sometimes it's quite slow when logging into the client, and uploading consumes some system resources without any speed advantages. I'm just simply introducing this service and don't recommend everyone to use it.
