General Help

The MailBigFile Multiple File Uploader allow you to send up to 10 files at a time on the Pro account and 20 files at a time on the Business account.

However, if you want to upload a whole folder, it is not directly possible due to current web browser limitations.

The way to get around this is to archive/compress (ZIP) the folder.

Click here to perform an upload speed test

There are many factors which affect upload speed.

These can include your computer, router, network, connection, ISP traffic and server load.

Due to the way that broadband technology works, uploading files at the maximum speed of your connection, can slow down your browsing and downloading on other services. This is due to the line being shared between uploading and downloading.

In general, most broadband connections have upload speeds which are less than 10% the speed of downloading. For instance. An ADSL2 connection with a 20mbps download speed may only upload at 1.9mbps. Some fibre to the cabinet connections (FTTC) may offer download speeds of around 80mbps and have an upload of 19mbps.

If your computer is busy with other tasks, or has software installed to which is monitoring transfers this may slow down your connection.

If you are on a wireless connection, please check your signal strength as this can have a dramatic effect on connection speeds. Distance is always a big factor with wireless technology. You may have a good signal strength, but if you are a large distance from the router, the data can become corrupt and thus slow the connection down. If you are experiencing slow speeds on wireless, try moving closer to the router or connecting via an ethernet cable.

Your network may have restrictions in place limiting the bandwidth. This is especially prevalent in larger companies. Please check with your IT Dept.

You can check your connection speed via the MailBigFile speed test, or another service such as www.speedtest.net.

Contact your ISP to see if there are any issues with their service, or on your local exchange. Also please check you haven't exceeded your allowance on your ISP, as they can sometime throttle your bandwidth.

If a transfer stops in the middle, this can be caused by a number of reasons.

Check your internet connection has not dropped.

Is your network busy?

Is there a bandwidth restriction in place on your companies network?

We keep our server status regularly updated.

You can not currently resume uploads on the website. If an upload fails you will need to begin the process from the start.

When you've just uploaded a file, it may take a short time before it becomes available.

Occasionally a file may not become available. This can be because the file did not upload correctly or due to the way in which it uploaded to the server. If you're experiencing this issue please contact our support team.

Sometimes when downloading a file you will see an "Access Denied" page. If this does occur, please contact our support team. with the file link.

Ensure you have successfully downloaded the file to your computer.

Check that the file size reported on the download page is the same as on your computer. Use properties on PC, and get info on a Mac.

If the file is a video, ensure you have all the required audio and video codecs.

In most cases, it is advisable to contact the sender of the file to discuss requirements.

If your computer downloads the file, but you aren't greeted with a 'download location' dialogue box, then please check your computer's downloads folder.

Once a file has expired, it is automatically removed from our servers. Unfortunately once a file has been removed, there is no way of retrieving it back.

If the recipient has not received an email notification, there are a few things you can try:

  1. Have the recipient check their spam/junk folder. Sometimes, the notification e-mail will end up in one of these folders.
  2. Ask the recipient to add 'noreply@mailbigfile.com' to the allowed websites in their security software or email filtering software.

All that is required to use MailBigFile is a modern web browser and an internet connection.

Please ensure you have adequate disk space if you are downloading a big file to your computer.

MailBigFile has been developed and tested to work with most modern web browsers.

We would highly recommend you use the latest version of Google Chrome, Firefox, Safari or Internet Explorer. Our developers here at MailBigFile recommend Google Chrome as their preferred browser.

If you are having problems uploading a file please ensure that you are running the most up-to-date version of that browser. Please try an alternate browser if possible. See www.whatbrowser.org for more information

Please also note that Internet Explorer 9 and below do not support HTML5 and therefore does not support the HTML5 4GB version of the new uploader.
