Martin, the card operating systems on the market usually provide no possibility to get a list of the files in a directory. Often, a directory file located in the MF of a card is used to store a list of the applications on the card. By reading this file, you can at least find out which applications are on the card. In most cases, the assumtion is that the application that deals with the card only needs to check whether the appropriate application DF is on the card and then knows the file IDs or short file IDs of all EFs in that DF as well as the keys to access them.

Hi! I would like to know if it is possible to retrieve information about what files(EF) and/or directories(DF) exist on a card (I have an Opencard DEMOCARD). Is it, for instance, possible to list files in a directory (DF)? If that's not possible I'll have to remember path and name of every file/directory I create and that seems somewhat difficult. regards /Martin Sigbj�rn Visit the OpenCard Framework's WWW site at http://www.opencard.org/ for access to documentation, code, presentations, and OCF announcements. --------------------------------------------------------------------------- -- To unsubscribe from the OCF Mailing list, send a mail to "[EMAIL PROTECTED]" with the word "unsubscribe" in the BODY of the message.
