Question

Hello,
I have developped a tool using c#.net (windows application) that searches all files under subdirectories and get the files attributes (creation date, author, size, type...), and then it displays the data in a richtexteditor object...
my tool works fine: it takes few seconds for hundreds of files. but when testing thousands of files it takes hours, like for 10 000 files it takes arround 12 hours, for 30 000 files it takes more than 40 hours

is there a way you can advice to enhance my code structure? do i need to use threads? or anything like.. i know the application is consuming lot of memory while running

thanks for any advice
