This function allows to select a local Zengin file stored on your PC. By selcting it and clicking on "Display Content", it's formatting will be verified, the files records are parsed and then displayed in your browser. This helps to identify formatting errors in Zengin files. It is quite common that instead of halfbyte, multibyte characters are inserted by accident that break the strict byte-aligned field order in Zengin records.
When the data is displayed, it is then possible to store the file into ZenginGen for future use or reference using the "Save To Server" button. Be extremly careful not to save any PRD data here, as PPI information becomes visible to others.
