Export View

When you’ve finished your design (or if you’re not and you’d just like to see what it looks like in PDF format for easier viewing), click on the Export button at the top of the screen to go through to the Export View. This is where you’ll enter the title of your project and check for any warning messages.

Export View will also warn you if there are any issues with your file before you export it. If all is in order and you simply click the Export button to have the software create the Master File ready for you to send to Momento for printing.

Accessing Export View

There are three ways you can access Export View:

Project Title

This is the name that will be used to identify your project once it is uploaded to the 'My Account' page on the Momento website.


Some of the warnings you might find in Export View are:

  • Cover background is white (just in case you wanted a coloured background)
  • No Cover design
  • Blank Pages
  • Edge Warning (a warning that a photo is too close to the edge and may be cut off)
  • Not enough pages (our minimum book size is 10 pages)
  • Quality warning (one or more of your photos may be too small to print clearly)
  • No Project Title
  • Spine text not set

You can click on the + icon next to the warning text to expand the list and view each individual warning message. Double click on any warning to be automatically directed to the location in your book where the problem exists. From here you can fix the issue by resizing or repositioning your photo or by adding new pages. Note: You can disregard the prompt and continue to export your project.

Edge Warning

An Edge Warning alert will pop up on screen when a photo has been placed too close to the page edge. This means that the image is not positioned within the Safe Area or it doesn't sit far enough off the edge of the page. You need to fix this issue to avoid having a strip of white down the page edge. To reposition the photo you can either move it back in to the Safe Area or move it further off the page until the Edge Warning disappears.

Quality Warning

This warning appears if one or more of your photos do not have enough pixels in the file to print at the size you have set. To fix the issue, reduce the size of the photo until the icon disappears to ensure your photo will print crisply. If you choose to keep the image as it is, we suggest you view your PDF Preview at at least 100% to ensure you are happy with the quality of the affected image before submitting for print.

File Export

By clicking on the Export button at the base of the Export View you will activate the creation of two different files from the software:

  • PDF: the Proof PDF allows you to preview and proof your design
  • MBF: the Master File is the file you will upload to Momento for ordering

The export may take a while as it is dependent on the size of your photo book and the power of your computer.  It generally takes around 30-60 seconds per page.  You will be able to see the progress of the export on your screen. The files created during the export process will take the name of the saved filename (not the Project Title).


Momento File Types

Momento Files

Proof file

The PROOF.pdf file is an important file for you to open and review thoroughly to ensure there are no design errors before you upload and order your file.  See the Proof PDF page for full details.

MBK file

The Momento Book File is the working file you open in the Momento software to edit and add to your project. It contains all the file pathways that tell the software where to find your photos and what you have done to these photos within your project. Note: You do not send the MBK file to Momento for printing. The MBK file saves to the Documents folder automatically, unless you select a different save location.

BAK file

The BAK file is a back up file that can be used should your MBK file become corrupt. The BAK files is saved or updated every time you manually save your MBK file. If this occurs, please contact our friendly customer service team.

Master File

We need to receive the Master File (MBF) in order to print your project. The Master File is created when you hit the export button in Export View of the software. Despite the large image files you may have included in your project, Master Files are usually sized at approximately 500KB to 1MB per page with a successful export i.e. a 25 page Regular Book is 25MB. Note: The file is a proprietary locked file and can only be opened by Momento.
