There is a free tool you can use when you are running out of cloud storage space or are reluctant to upload important files to someone else's server. It is... Syncthingno see.
What kind of program is it?
Syncthing is a free, open-source file synchronization program. Unlike Google Drive or Dropbox, which upload files to a central server, your computer and other devices connect directly to exchange files. Therefore, your files are never stored on the Syncthing server.
Key Features
- Available on various operating systems such as Windows, macOS, and Linux
- Communication between devices is encrypted with TLS, and only devices I allow can connect.
- You can select multiple folders and synchronize them differently on each device.
- Check settings and progress on the web browser screen (Web GUI).
- Editing the same file on two devices simultaneously can cause conflicts, so it is recommended to check the version control settings for important documents together.
It suits someone like this
It is particularly useful for those who want to automatically match photos and documents between their home computer and laptop, or for those who want to transfer large files without cloud charges. However, both devices must be turned on for synchronization to occur, and the official iPhone app may have limitations, so please check device support before installation. Synchronization is different from backup—deleting something from one device can cause it to be deleted from the other, so it is safer to keep a separate backup of important files.
I recommend starting with a single test folder, registering device IDs, and getting familiar with the process by sharing a folder.
