    Viewing files sent by Apple Macs (Outlook 97 Sr2)

    One of our users' sisters often sends her various files to view, usually humourous jpg's.

    The strange thing is that we never seem to be able to see them very easily. The files come through in Outlook with strange extensions i.e. "filename.jpg 2". However when we save them locally and remove the " 2" element of the extension the file when opened in MS Photo Editor merely says "'Can't Determine Type".

    Even more strange is that if you try and double click the image in the outlook message the system pops up and says that the system does not know how to open the "filename.jpg 2.bin". Note the addition of the .bin.

    If I try and email to another user the initial saved to disk version with the " 2" removed then the system reports that it does not know how to open the "filename.jpg.bin". Note the retention of the .bin still.

    Neither Photo Editor or IE can open these files. The only success I have had is with Irfanview and Micrografx Picture Publisher which appear to not worry about the .bin.

    Initially this confused me no end. Now I learn that the sender is using a Mac system. Is the file extension I'm seeing something I can deal with. Other files she's sent have also had similiar extensions added and hidden away.

    Is there any way of either a) the sender ensuring compatibility or [img]/forums/images/smilies/cool.gif[/img] removing the .bin extension short of opening in an app that obviously understands the .bin (ie Irfanview) and saving in another format.

    Many thanks <img src=/S/confused.gif border=0 alt=confused width=15 height=20>

    i beleive a bin is a mac verison of a compressed file - i'm not sure if winzip can open it or if you'll need stuffit for windows. http://www.aladdinsys.com/

    What you are seeing is a "MacBinary II encoded file" which may or may not be compressed using stuffit. You may get it to open just by saving the file/attachment with a .jpg extension.

    The users' sister probably has her e-mail application set to send attachments as binary files. Depending upon which one she uses she should change it back to the default. In any case the Mac user should be told that whenever sending an attachment of an application that is available on both the Mac and Windows (i.e. .jpg, .gif, .doc, dot, .xls etc. etc.) it is a VERY good idea to simplify the process by adding the appropriate three letter extension to the file name herself before sending it.

    Mac files contain information about which application created it in the data fork which is not understood by a PC. For the PC to know which application to use the correct three letter extension has to be added to the file name.
