Thanks very much for the offer of help. My trouble is I am not a programmer and don't have any programming tools except for SB5, so even if you told me what to do to implement it I wouldn't be able to! :-(

I have tried using GetFileInfo to get the size of the folder, and the size of the folder\*.* but these don't work either. This also means i have no way of checking the size of a folder and it's contents during an installation, which would also be handy.

My best idea so far is to search for a large number of commonly found file extensions and see if anything turns up on any of the searches, or in the case of size testing to add them all up individually. Just means a lot of code and the end result cannot be very accurate...

How about freeware DLLs that do things like this? Do you know where I could find one?

Regards,

Jeff
