ⓘ SNP file format

The SNP file format was used by Microsoft Access to store Report Snapshots in a single file which can be viewed and printed by the Microsoft Snapshot Viewer, a Windows program available free of charge from Microsoft that allows report output to be viewed without requiring Access. Support for the format was discontinued in Access 2010 and later versions, Access reports can be exported in PDF/XPS and Excel formats viewable on many platforms.

SNP files are based on the Microsoft compound file binary format CFBF, which is also the basis for rich edit format AAF. CFBF is a reasonably simple container format which can store multiple files, directories, and so on. For SNP files, Microsoft Access uses CFBF to store each page as a separate enhanced Metafile EMF format contains all the graphics commands needed to reproduce the page.

The last entry CFBF in the SNP file is the header file mainly contains a devmode structure. The data from this structure is used to display the SNP file in snapshot viewer Microsoft, in conjunction with the selected default printer.

As CFBF files are not compressed Cab format Microsoft used to reduce the size of the CFBF, producing a file that can be only a few KB for each page of text and simple graphics - lines, rectangles, etc.
