Frequently Asked Questions

What is the MASV Desktop App?

The MASV app for desktop is a high-performance file transfer platform designed to share large files faster than a web browser, with greater performance and stability. The MASV Desktop App can be used to share petabytes of data and perform automated file transfers without any development effort.

What are the features of the MASV Desktop App?

The MASV Desktop App contains the following features:

  • A clean, minimalist interface
  • Client-side acceleration for uploads and downloads
  • Automatic transfer resumptions in case of network interruption
  • Ability to limit bandwidth usage with Speed Limits
  • Watch Folder automations

  • Multiconnect internet bonding for greater performance
  • Support for 10-gigabit internet
  • An itemized log of transfers
  • Drag-and-drop upload

  • Ability to set Transfer Priority

How does the MASV Desktop App work?

The MASV Desktop app is very easy to use. Simply drag and drop files onto the main app homepage to upload files. From there, the true power of the MASV App comes into play.

All MASV transfers moving through the Desktop App travel across a private cloud highway at max speed. Since the the MASV App is not bound by the limitations of a web browser, it is more efficient and reliable.

Transfer data is stored in the cloud during transit. If there’s a network outage, the MASV App will recover once a connection is detected and resume the transfer without any loss in data.

The MASV app leverages MASV’s proprietary cloud-acceleration technology to ease congestion and be fair to others on a shared network.

Additionally, the MASV app comes with a ton of exclusive features to help make large file transfers more manageable, such as:

  • Multiconnect internet bonding
  • Support for 10-gigabit internet
  • Assign a priority status
  • Add Speed Limits to control bandwidth usage
  • Watch Folder automations

How do the MASV App’s transfer control features work?

The MASV Desktop App has several transfer control features that keep users in charge of the performance of their transfers at all times:

  • Transfer Priority allows users to easily send rush deliveries without the asset having to wait in a transfer queue. Without Transfer Priority, power users must manually turn off all other ongoing transfers to allow the rush delivery to reach its destination on time. While not a mandatory tool, users who need to can assign a priority status of highest, high, default, low, or lowest to all transfers. It’s important to note that the Transfer Priority tool does not stop other transfers in progress; rather, it redistributes bandwidth to the highest priority transfers.
  • Speed Limits are another control feature that allow users to limit the bandwidth MASV uses based on the day or the week or time of day. This tool is most valuable if you share a network with others and don’t want to hog all bandwidth, or if you need to cut down on network provider fees. Speed Limits allow users to set separate max speeds for uploads and downloads, along with specifying which days of the week and times of day those limits should apply (a common use case is to reduce bandwidth during the day, when others are on the network, and remove Speed Limits overnight).
  • Pause and Resume functionality allows users to manually pause and resume file transfers with a click. If you’ve got multiple transfers going, pausing a transfer will automatically redirect bandwidth to other files in progress. Or you can use Pause and Resume if you need more bandwidth for another application, such as video conferencing.
