MEGA

ApplicationMega Limited

Also called megasync, mega.nz, mega.io

Mega LimitedProductivity

A cloud client known for a large free quota and MEGA's encryption story. The process is MEGAsync.exe. It is not Dropbox.

What you need to know

MEGAsync.exe is MEGA. Dropbox.exe is Dropbox.

MEGA's desktop client syncs a mega.io account. Dropbox is a different vendor. A mega.nz link can also download in a browser without this exe.

What is it?: Cloud sync
Still current?: Yes, see Current status
Official download?: Use the vendor link in this article

Feex says

If MEGAsync.exe is uploading, that is MEGA, not Dropbox. I would not pause Dropbox.exe to stop this transfer.

What is MEGA?

MEGA is Mega Limited's cloud. MEGAsync.exe is the Windows sync app. Dropbox is a different company. The website can download a file without this exe.

If you have never used it

If someone sent a mega.nz or mega.io link and you want a synced folder, this is MEGA, not Dropbox. Download MEGAsync from mega.io/desktop. Dropbox.exe is Dropbox, Inc. MEGA advertises client-side encryption and a large free allowance. Those claims are MEGA's, not Dropbox's.

What is it used for?

Folder sync

A MEGA folder in Explorer. Dropbox.exe will not see that namespace.

Large free quota MEGA advertises

The free allowance is a MEGA plan detail. Dropbox's free tier is smaller and a different contract.

MEGA's encryption story

MEGA documents keys and zero-knowledge marketing. Dropbox is not this model. Read MEGA's own help, not a forum summary.

Who is it for?

People who already have a MEGA account
Users who want a large free cloud and accept MEGA's terms
Anyone who should not install Dropbox for a mega.io folder

Current status

Actively developed. This article is the Windows MEGAsync client, not MEGAchat alone.

How old is it?

MEGA launched in 2013 after Megaupload. Dropbox launched in 2008. They are different vendors and different encryption stories. A 2010s "Megaupload" headline is not this client.

Versions

Major channels first. Exact build numbers are not all verified here.

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	A current supported Windows 10 or Windows 11 release, per the vendor
RAM	Enough for Windows plus this app. Heavy projects want more.

Resource profile

CPU demand: Follows what you open inside the app
RAM demand: Follows documents, tabs, or libraries

Installed processes

These executables belong to this product when it is installed.

Installed processes
MEGAsync.exe	MEGA desktop client

Startup components

MEGAsync can start with Windows from its own setting. That is not Dropbox.

File locations

Common MEGA locations
Typical install	C:\Users\<you>\AppData\Local\MEGAsync\MEGAsync.exe

File formats

whatever you store in MEGA

Common problems

Two clouds on one folder

MEGA plus Dropbox on the same tree double-writes. Move one root.

Transfer quota messages

MEGA has transfer limits on some plans. That is an account cap, not a broken disk.

Getting unstuck

Install from mega.io/desktop

A "MEGA sync free" search ad is the wrong file. Dropbox.com/install is the sibling.

Confirm MEGAsync.exe under the MEGA folder

Dropbox.exe is Dropbox. Open file location if both trays are busy.

Use mega.io in a browser for a one-off download

You do not need the desktop client to fetch a single shared file.

Alternatives

Dropbox, OneDrive, and pCloud overlap. Dropbox is the sibling this article is not.

Official help and downloads

Start with the vendor. Random exe sites are not a support channel.

First sync wants disk and network. An SSD helps.
