megasync.exe is the MEGA Sync desktop client that keeps your MEGA cloud files synchronized across devices. It runs in the background, watches your chosen folders for changes, and uploads or downloads updates to your MEGA account, providing offline access via local caches and real-time syncing when online.
MEGASync uses a background service with file watchers and worker threads to compute deltas and push changes to MEGA's servers via TLS, then reconciles local and cloud copies while honoring selective sync settings.
Quick Fact: MEGASync has supported real-time synchronization across devices since early MEGA releases, using a persistent background service to monitor folders and handle conflict resolution.
