Altium: Filenames with sheet numbers
Don't do Scheet Numbers in File names! Use functional names in the scheets like Powersupply.schdoc, CPU_digital.schdoc, CPU_supply.schdoc, Communication.schdoc, CAN.schdoc, SPI.schdoc, ...
Make a hierachical schematic design and use a header in the schematic witch has the parameters &quot;SheetNumber&quot; and &quot;SheetTotal&quot;.
Use Tools -&gt; Anotation -&gt; &quot;Number schematic sheets&quot; to set the parameters of every sheet correctly. When you add or remove a sheet just run the anotation again. See
