extracting MIG file on windows 7

I have an XP laptop and a Windows7 desktop. I wanted to reinstall xp on the laptop and did the mistake of using WET to transfer files to a stick as an MIG file only later to discover that xp doesn't recognize this file. Windows7 recognizes this file. But if I double click on this file it immediately starts copying the files (at least it displays this message and starts spinning). I then cancelled the action as I didn't want to extract into my Windows7 desktop. How can I extract the files into a separate folder so I can then take them to the laptop and transfer.

thanks

I found this, it may solve your problem

thanks
I tried both migrecover4 and migrecover3 - they both produce a large number of files named "1,2,3, etc" without any file extension - useless. I now need to be able to extract the files using the mircoft WET tool but choosing a single folder for all the files to go into. Anyone has a solution?

According to their site

1. Type the bolded text, and press <Enter> MIGRECOVER.EXE C:\SaveData.MIG C:\MIGRECOVER\RECOVER
2. The data will be extracted, if successful, to C:\MigRecover\Recover folder

That looks to me like it will extract to folder as you said you needed.
