WiFi File Transfer

I could not get either Samsung Link or Kies Air to work.  One wanted a rooted smartphone, the other would not usefully do anything.  But WiFi File Explorer seems to do the trick.  The Android side is here.  It seems to set up a http server, which you interrogate through the smartphone's IP address and port 8000.  You can delete, copy, zip, and unzip files on the smartphone's file system, and download files to the PC.  Unfortunately, download zips the files before downloading.  This is certainly efficient for moving many files, but for moving images and video, not so much, since JPG and most video formats are already quite compressed.
