Yes, and it's iMac not IMAC. I know it's kind of obnoxious with the leading lowercase i, but I didn't make it up.
In any case, OS X has native read-only support for NTFS, and full read-write support for FAT12/16/32 and ExFAT (sometimes known as FAT64).
I have an external XP formatted drive filled with data stored from a PC that is now deceased. My office replacement machine runs Windows7 and can't read the drive. I know Mac is more sophisticated than Windows. I have an IMAC running Snow Leopard. Is there any chance I can read and save these docs? I have Microsoft Office running on my Mac.
