Hi, I thought you might find this small project of mine interesting around here.
The native file explorer doesn't show folder sizes, so I decided to see what it takes to add this ability. At first, I created a Windhawk mod which hooks the relevant function and calculates the folder size when it's requested. This approach was obviously slow for folders with a large amount of files (although not as slow as I expected), and several users suggested to do what Everything does, since it's so fast![:)]( "Smile")
I didn't feel like implementing a filesystem indexer, but I figured that I can use the Everything SDK, which I happily discovered to exist.
The result:

Check out the mod page for installation and for the source code: Better file sizes in Explorer details.
One thing that could still be improved is that currently, each folder size query triggers an IPC call, which in turn sends the WM_COPYDATA message and waits for a reply. It's not as slow as actually calculating the folder size, but it's slightly noticeable, especially when sorting by size. I'm not sure what can be an alternative which is faster but is still as convenient. It's also not a standard use case - given the Explorer source code, I'd just query all the necessary sizes in one go - so perhaps it's not worth optimizing for. Just sharing in case you have any ideas I didn't think of.
