Microsoft Access database snapshot file
SNP is a file extension for a database snapshot report used by Microsoft Access. SNP stands for SNaPshot report. Snapshot reports are created by Microsoft Access, but can be used my Microsoft's Snapshot Viewer on computers that don't have Access installed.
SNP files are based upon Microsoft's Compound File Binary Format, which is a simple container format used to store multiple files, directories and graphics commands which can be used to recreate the report.
