file sync

File synchronization (file sync) is a process that ensures copies of your files on different devices or locations stay consistent and up-to-date. When you make changes to a file on one device, the sync software automatically updates the same file elsewhere, so you always have the latest version. This is useful for working across multiple computers, smartphones, or cloud storage services, allowing seamless access and preventing data loss. File sync typically runs in the background, continuously monitoring changes, and helps maintain data consistency without manual effort.
