What does File Sync mean?

Syncing file is to transfer multiple files or folders to different locations, whatever email, digital photos, MP3, videos etc, and if there are any changes happen, the file sync software will sync changes from source directory to destination directory easily and quickly. The storage can be internal hard drive, external hard drive, USB flash drive, network drive, share/NAS etc.

The manual copy and paste we often use is actually a one-time synchronization, but this approach is not suitable for those who need to synchronise data over a long period of time, especially for large amounts of data. 

So in order to sync files from one folder to another and update all the changes automatically, a file sync software is often required. With it, we can better cope with the following usage scenarios:

  • Want to automatically copy a folder and its subsequent data changes to another location
  • Working on a project with someone and need both parties to see the latest version of certain files
  • Want to always keep an up-to-date copy of important data as a double insurance...
