I think you can use VBS triggered from FileMaker (or on its own) to create the shortcut and attach the file. The biggest issue, as far as I remember, is the file has to be on a target computer unless you are happy with the stock files (e.g. c:\windows\system32\shell32.dll).
I do not have Windows handy, will try tomorrow if someone does not come up with a better solution. BTW, how are you deploying your shortcuts now?
OK, try the file I uploaded. You can change urls to fmp format in the field and link to a different icon.
This is for Windows only! MAC would use a different format, although the principle is the same.
In short, the web shortcuts are text files. Their format and the extension varies, depending on a platform and the browser. You will need to launch you fmp url, get back to the browser and create the shortcut, open the shortcut with a text editor and copy/paste into the FileMaker field.
IE shortcut could link to a web url, which is a bonus.
