Here's a trick to remove empty directories using XXCOPY.

XXCOPY \yourdir\ /RSY /S /X*

Explanation:

/RSY remove source directory (in this case \yourdir\)
/S including subdirectories
/X* exclude all files (* == same as *.* in Win32)

This technique takes advantage of the exclusion feature which
does not delete any existing file in the directory. Since
a subdirectory with a file (or subdirectory) won't be deleted,
the only subdirectories that are deleted are empty ones.
To make this command work better, you may want to add
the following switches

/H include hidden directories
/R handle read-only directories
/PD0 suppress prompt on directory
/Q2 quiet (no display on skipped files)

--------------------------------------

Incidentally, the following XXCOPY command line will do the opposite
(delete all files and leave directory skeleton behind)

XXCOPY \yourdir\ /RSY /S /ED /PD0

here,

/ED preserve an empty directory

Again, you may add /H /R /Q2 to make it more bullet-proof.
