Open SNP File
The SNP format and extension file is a snapshot of a report created in Microsoft Access.
About Microsoft Access
Microsoft Access is a database management system included in the professional editions of the Microsoft Office suite, and uses relational database concepts and can be managed through queries and reports.
In this case, the SNP file preserves the layout of the report, including text and graphics.
In this way, the SNP file allows the report to be viewed by someone who does not have Access installed on their computer.
Today, however, SNP files can be viewed using the free Microsoft Snapshot Viewer.
