The genuine MEGAsync.exe file is a software component of MegaSync by mega.nz.
MEGAsync is like DropBox: MEGAsync is an installable application that synchronises folders between your computer and your MEGA Cloud Drive. All files and subfolders will be replicated in both directions. Changes that you make on your device will also be made on the MEGA Cloud Drive in near to real time (within the limits of link / system latency and file transfer times). Similarly, changes made in your MEGA Cloud Drive (such as renaming, moving and deleting) will also be made to the synced folders on your device.
MEGAsync is a TWO WAY sync. The folders you nominate to be synced will mirror any action!
Whatever you add / delete to / from your sync folder(s) on your device locally gets added / deleted in your sync folder(s) in Cloud Drive and vice versa. Overwritten or deleted files can be found in your local sync hidden folder called Rubbish or .debris and in your Cloud Drive's SyncDebris folder in the Rubbish Bin.
