     Hi,

       I would like to upload into the SharePoint document library large file (over 100MB PDF file). Is it possible to display this document in callout document preview? How much will it decrease performance and resources? First of all is it possible to preview such large file?

     Best regards,

     Kamil

    Yes you can preview PDF files.  And yes you can preview files that are that large.  There shouldn't be a major decrease in performance because SharePoint renders the preview page by page.  I do suspect you will need to make sure you have enough cache space on the disk of the Office Web Apps server to show a file that large, but that cache space is easily expandable.  There is a max size on Excel workbooks, but I don't think that applies to PDF (Word) files since they are processed differently.

    1. Office Web Apps can not be installed on a server running SharePoint.  It must be installed on a separate server.  Check the requirements here:

    https://technet.microsoft.com/en-us/library/jj219435.aspx#software

    2. PDF files will be rendered by the OWA Word module if you are at least at SP1 for SharePoint.  You can configure the RTM copy of SharePoint 2013 to work that way also, but I recommend upgrading to SP1 or later.

    3. Office Web Apps presents documents etc in page size chunks.  It caches a lot of content on a local disk while it is working to prevent having to go back to the database as frequently. The amount of disk space used for caching is configurable.

    Ok, great but I have 3 more questions:

    1. Does it mean that OWA must be installed on seperated server - is it not possible to use the same server instance where SharePoint is currently installed?

    2. Additionaly as I verified PDF is not supported by default because Office package where Word, excel, powerpoint and note are only supported?

    3. What does it mean 'cache space on the disk'?

    Thanx for reply!
