Merging Folder (on rename)

[nsp]

I would like to have an option to merge the content of a folder into an existing one.

Ex I have folders Sources_Java and Sources during rename, i want to merge the content of Sources_java into Sources.

When i want to rename Sources_Java to Sources i get a warning. I can only cancel the operation or move the current folder but no option to merge is proposed.

You need to enter both folders and move the contents instead of moving the folder by itself.

This is what i actually do (When not using external script) but if it is a lot of operations that could be solved by a single option !
---->
/1/ Select name or open target folder.
/2/ Enter inside source folder
/3/ remove filter if some exists select all files
/4/move to target.
/5/ return to ..
/6/ delete folder

Another augment to provide it is that it is the standard behavior in explorer stating at windows seven.

Can you consider proposing the merge or move content option during rename if the target name already exist ?

This is the default behavior with Explorer and it is very convenient. Recently i have to deal with very long path and the filename in %L are tuncated and i cannot anymore use my script to move content of multiple folder into a single one.
