I am using the Homegroup feature in Windows 7. Usually, the folders I have specified to be shared are available across all of the computers on the Homegroup, as desired. 

Unfortunately, when new files are added to these folders, there is a significant and seemingly random delay before they are pushed to the other computers. I assume that the way Homegroup works is that it runs some service in the background and that after a set period of time, this rescans shared folders and shares any new files found.

Is there any way I can manually push files to the Homegroup so that they are available as soon as I add them to one of my shared libraries?
