How to delete files & left directory structure intact?
 

Do you know any program for Windows which can do this:

Delete cartain file type (ie. jpg files) in selected directory and its subdirectories and left directory structure and all others files intact.

Any ideas?

Try to do it with batch scripting.

Here's a really dumb way in DOS:

Open up your dos prompt.
CD into the directory you want to recursively remove files from.
Type: dir *.jpg /S/B > list.bat
Open up "list.bat" in an editor and prepend each line with "del " (using a regular expression replace)
Run that batch file.

-- totally dumb, but since I don't know of any program either, that's how I'd do it.

You can do it without a program this way--

start>>
Search>>
Pictures, Music, or Video>>
Check the box-- Pictures and Photos>>
Use Advanced>>
then select your top folder to search and click 'Search' and it will display all image files in that folder and subs

edit--
of course then you -- ctrl+a and hit delete
