The next BK installer after 29 October 2024 will contain an improved Command Line Interface (CLI) AND it will also contain a new command "TELEMAC". This new command will have 1 option (for now) that allows you to list the properties of all SLF files in a directory. It also provides an option to write the results of the search into a CSV file that can then be opened in Blue Kenue via "File > Import > Comma Separated File".
Kindly... Alan
