Boardview file in FZ format for the ASUS M5A97 LE R2.0 desktop motherboard, with r1.00A in the name, likely the file or board version. FZ boardviews open in FlexBV, OpenBoardView and similar programs and show part placement and net connections. On a desktop board this helps trace VRM phases, locate a shorted MOSFET, check the SPI BIOS chip area or follow signals from slots. Small size is normal for this format. Make sure the board revision printed near the slots or on the PCB matches R2.0.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardviews. Enginerys does not host this file.
