File Synchronization is the process of ensuring that files in two or more locations are updated to reflect the most current version. This can occur between devices, such as a computer and a smartphone, or between cloud storage services. The goal is to keep files consistent, so any changes made in one location are automatically reflected in the others. There are various methods for file synchronization, including manual syncing, where users initiate the process, and automatic syncing, which occurs in real-time or at scheduled intervals. This technology is essential for collaboration, data backup, and maintaining access to the latest information across multiple devices.
