This button converts all existing S57/S63 charts

The button is there on popular request, and means that O don't stop to process a chart when encountered the first time, but instead process all charts
The process can take quite some time, depending on your system.
If you already done the new conversion once and add a chart, pressing the button will be fast as only the new chart is processed.
There is also a new naming system for the processed files. It's a good idea to delete the SENC folder the first time you use the new beta, and then press "Prepare all ENC charts". The only reason for this is to save some space on your hard desk.
