Extracting the name of a CD for an archiving macro

[Gareth Howell]

H, I'm looking for a bit of help on a small cataloging macro I'm writing. We have thousands of images spread across loads of CDs and external drives which make them very hard to search for data. I am trying to write a macro to undertake the archiving of these CDs. The problem I have is getting the CD name from the CD. Using getDirectory I can map to the drive (e.g. E:, not a lot of use!) and get subfolder names etc but not the name of the CD (e.g BMBGJH_CD133). Can anyone help? Is there a 'get' command I can use? Of use maybe is that the name of the CD is burned as a text file on the CD; can I extract that?
Thanks in advance for your help.

Since you're using Windows and mention E: drive as your CD drive, use:

    exec("cmd /C vol E:");

The ImageJ log window will show the string result.  To process the
returned string for the label you could do something like this:

    cd_drive = "E"
    // Run Windows' `vol` command.
    vol = exec("cmd /C vol " + cd_drive + ":");
    // Check if it has a label.
    label = "none"
    if (indexOf(vol, " has no label.") == -1)
    {
        start = indexOf(vol, " is ") + lengthOf(" is ");
        end = indexOf(vol, "\n");
        label = substring(vol, start, end);
    }
    print(cd_drive + ": Label = " + label);

Hi Pariksheet,
Thanks for the response. I actually decided to generate a dialog so that the user could enter their CD name into the macro prior to it running the datebase macro. I guessed they would be putting individual CDs into the drive anyway so an additional step would not matter so much. Also they can add other info if they wished that would aid searching the database.
Thank you for your reply though, i'll keep a record of it if i need to develop it further.
