FolderMove
 

FolderMove - Not a real reverse engineering tool;
will move all files and folders to a subfolder named html.
Source code C# included.

I'm sorry, but to understand (since I could not download), how is it different from a move command that moves everything into a folder?

Like
cd <to the required directory>
mkdir html
mv * ./html/
mv .* ./html

Thanks and please excuse if the tool does something different from the above understanding.

It is mass folder move; it will move and create subdirectory html of each subdirectory of the directory specified.
