I can’t seem to login

How fast can I send files?
Sendplus will utilize around 80% of your available bandwidth in accelerated mode. It won’t monopolize all your connection so you can carry on sending emails and browsing the internet at the same time.

Does my recipient need to download Sendplus to retrieve the files?
No, once registered, your recipient can download the files you have sent them by logging into the Sendplus website. However, there are some advantages to downloading and installing the desktop client.

To download from the website your recipient must wait for you to finish uploading the file, with the download client they can start downloading the files immediately without waiting for the upload to complete. Only desktop client downloads take advantage of the network acceleration, so the client will download that content much faster.

Do I need any browser plugins?
No browser plugins are required to send or receive content. Files can be downloaded via the desktop application.

How can I track my file transfer?
The desktop client and the web application will show you if the recipient has started downloading the content, how much of it they have downloaded, and how long it will take to download the files. It will also show if the recipient has cancelled or paused the download. The transfer monitor will show a large green tick when the transfer is complete, and the recipient has finished downloading the content.

Is there a mobile version of your application?
The Sendplus web application will scale to mobile devices, with an optimized UI.

Can I send multiple files or folder structures?
