Directories within File List in Doxygen?

I am documenting my project right now! So as it stands, under "File List", I see 开发者_如何学运维something like this:

File List
Folder1/Sub_Folder1/File01
Folder1/Sub_Folder1/File02
Folder2/Sub_Folder1/File01

And what I'd like to see instead is this:

File List
Folder1
Folder2

Upon expending Folder1, it should look like this:

File List
Folder1
       \Sub_Folder1
Folder2

Is this possible in Doxygen?

Thank you

Found it! In the doxygen configuration file..

SHOW_DIRECTORIES = YES

Will do the trick ;)
