Directory Sizes and Performance

[Flinky Wisty Pomm]

Hi all,

I need to regularly traverse a large networked file system and return
a list of directories and their respective sizes. The file system is
large enough that performance is a serious concern.

As well as the recursive [File/Directory]Info solution, I've seen
reference to using the FileSystemObject or calls to FindFirstFile/
FindNextFile via COM interop.

Does anybody know the fastest way of doing this in .Net?

Whatever you do, do not use COM interop if you care for performance. I
believe there are some classes in BCL that can retrieve information u need ,
like querying AD (active directoy) that type of thing.

The File/DirectoryInfo and other classes like
Directory.GetFiles/GetDirectories also use FindFirstFile/FindNextFile via
P/Interop. In the case of FileInfo, these are used once for each FileInfo.
In case of GetFiles/GetDirectories, these are used once for each
enumeration.
