Where did you get that file?
When you download things in Safari, DownloadComment will put the original URL into the saved file's Spotlight Comments. Now you'll always know where your downloads came from. Keep track of where your downloads came from. The Comments field can be accessed in the Finder by choosing to "Get Info" on a file.
This functionality was part of most browsers on OS 9 but is missing from Safari. DownloadComment brings it back.
DownloadComment v1.1.1 (2/25/06) adds support for Macs with an Intel processor.
