Rclone is a treasure I recently discovered in the form of a command-line program. With Rclone, I can finally solve the problem of syncing files perfectly across multiple cloud storage services (such as Dropbox, Google Drive, OneDrive, etc.).

In the past, to save documents simultaneously to Dropbox and OneDrive, I had to install both of these apps on my computer and nest the Dropbox folder inside the OneDrive folder. This ensured that all files would sync to both cloud services. However, this setup often caused a variety of issues, such as duplicate files and synchronization errors.

Now, with Rclone, I only need one cloud storage app installed on my computer. I use Dropbox as my main cloud storage tool and can apply Rclone to copy or sync files from Dropbox to other cloud services, such as OneDrive or Google Drive. The operation is very simple, requiring just a few basic commands, and there are plenty of tutorials available online. Of course, this is just one feature of Rclone—there are many other more advanced uses as well.

That said, storing files in the cloud greatly improves convenience and file security. For instance, you can search for any file on your phone at any time, and you don't need to worry about losing files due to physical hard drive failure (although it's still very important to keep a local copy). However, from a privacy protection perspective, it's best not to upload files that involve sensitive information to cloud storage.

I've always been very interested in email, cloud storage, cloud notes, and similar tools. Over the years, I’ve experimented with quite a few of them. Often, the core functionality of these apps hasn't surprised me much, but the tinkering itself is endlessly enjoyable. This reminds me of the days more than 10 years ago when I spent all my time flashing ROMs on my phone.
