I often download themes from which I only use the wallpapers or some of the icons or sounds or cursors. This is possible because, after unzipping them, what I get is a folder of all the separate parts of the theme. However, the Windows 7 themes unzip as a single file (with a credits txt file). Is there any way to extract the parts from that file so that I can use them on my Windows XP system?
That file might also be zipped and therefore might be extractable. I suggest you use 7-zip to extract. Right-click the theme pack and use 7-zip’s "Extract here..." option.
