Now Available: Simpler File Transfer with the New MASV Desktop App (Linux & Mac & Windows)

The new MASV Desktop app makes it even easier and more reliable to send and receive files using People love MASV for its ability to send enormous files and folders through the browser with no plugins, no software, no subscriptions and no headaches.

But when you start sending the really big files, there are significant benefits to using a desktop app that retries relentlessly, thus working around network problems that will occasionally arise when sending huge files over the Web. And so the MASV Desktop App was born.

What's New in Public Beta v0.9.2
MASV Desktop app (Beta) offers time-saving features including:

  • Resilient transfer performance: MASV Desktop gives you an unparalleled level of transfer resilience. Whether you close your laptop, accidentally unplug a drive, lose wifi or innumerable other scenarios, MASV Desktop will relentlessly power your transfers forward when your connectivity returns.

  • Continuous retry: Networks bog down. It happens. Whether it’s a problem with your local connection, a problem with the recipient’s, or an issue out in the Cloud, MASV Desktop won’t bat an eye--it will continuously attempt to send every packet of your transfer until it hits the destination.

  • Drag and Drop Simplicity: Grab individual files or complete folders and drag to the app for quick and easy content selection. Click next, add your recipient info, then send. Simple.

  • Support for MASV Teams: Most users of MASV use Teams. A MASV Team provides easy user-management, especially if you are working on multiple projects and production crews. Teams let you invite members to your MASV team and give them permission to access transfers. MASV Desktop allows you to define which team your transfer belongs to. To define new teams, set roles or restrictions or monitor billing and usage, use the MASV web client at

  • Faster, zip-free transfer: offers the unique ability to send complete folders, retaining folder structure even when sending 100s of thousands of files. Downloading from the browser means you need time and sufficient swap space on your hard disk to allow unpacking of the .zip archive generates. For many this is fine, but for those of us with perpetually full hard drives, it can be a hassle.

    MASV Desktop sends folders zip-free. Simply ensure both sender and recipient is using the app, and your large folders will transfer faster, with no unzipping required.

  • Extreme speeds that don't kill your network: You’ll find a lot of claims about who has the fastest transfers. If you try MASV Desktop you’ll quickly learn the truth: MASV delivers huge transfers faster and more reliably than the competition. Even better, MASV’s proprietary TCP acceleration technology means we send your content fast, without hogging the network; you and your team won’t need to trade a slow, congested network in one application for blazing transfer speed. With MASV, you get both.

  • Coming Soon! Resume: In addition to retrying your transfer through network issues, the MASV Desktop will resume after experiencing an issue on your PC. Did your battery die? Did your kid yank a network cable? Did you close your laptop and go home for dinner? Through all of these and more, MASV Desktop will resume your transfer after a disruption. Will it resume if you throw your laptop in the lake? If your laptop survives--yes.

  • Future Updates: Watch folders and download management are just two of the features on our roadmap -- do you want to see something else? Send us feedback via our form, here:

Please download MASV Desktop and try it out, then tell us how it works for you! We think you’ll find it just as convenient as the browser, but with the potential to send even bigger files with superior speed and reliability. We’re especially keen to hear how it works for you on 1TB+ files and folders with thousands+ components.
