The directory contained .dt2 and .id2 files. When I checked .dt2 files with FileAlyzer, I found that they were actually GIF files. Most were GIF89a files, but some were GIF87a files as is revealed by the first 6 bytes in the files. GIF89a files have 47 49 46 38 39 61 as the first six bytes in the files while GIF87a files have 47 49 46 38 37 61 as the first six bytes. If you change the extension on a file from .dt2 to .gif, you can view the file with an image viewing program.

There is a .dt2 and .id2 file for each emoticon with names similar to the example shown below.

ZysU6LltaOP0MVYOBvV4YcbnHr4=.dt2
ZysU6LltaOP0MVYOBvV4YcbnHr4=.id2

These are associated with the emoticons you see in the Custom emoticons section when you select an emoticon within Windows Live Messenger.

I was able to transfer all of the custom icons for Windows Live Messenger from the Windows XP system to the Windows 7 system, by copying all the files in the CustomIcons folder on the Windows XP system to that folder on the Windows 7 system. Where the files already exist, you can choose to skip or copy over those files.

Note: if you have Windows Live Messenger open on the destination system at the time you copy the files to it, you will need to close all Windows Live Messenger windows and close the program and then reopen it to see the custom icons you copied.

To install the software, once you've downloaded it, unzip the contents of the zip file, which you can do from a shell prompt with the unzip command. Then use the Finder to locate the .mpkg file that was extracted from the .zip file. Double-click on it to start the MacGPG2 Installer.

Click on Continue to continue with the installation. The next step will be to view the Read Me information, followed by the display of the GNU General Public License Version 3, which covers the use of the software. After agreeing to the license, you will be informed of the amount of space that will be used by the software, which is 21.6 MB for version 2.0.14RC2. When you proceed with the installation, the gpg executable will be installed in /usr/local/bin.

You can see other files installed during the installation with lsbom -fls /Library/Receipts/macgpg2.pkg/Contents/Archive.bom.

Your keyrings, such as pubring.gpg, will be installed in /Users/acctname/.gnupg/. where acctname represents the particular account you are using. If you have keyrings already on another system, you can copy those keyrings to that location. I.e., you can copy pubring.gpg, secring.gpg, and trustdb.gpg from the other system. You can see what keys are in your public keyring with gpg --list-keys.
