How to move folders of certain size in command line?

In my external HDD I have two partitions, one is for Mac and the other for Windows (FAT32). Since my Mac partition is almost full due to Time Machine backup, I want to move some of my old folders (in which are movies) from the Mac partition to the Windows partition. However, the FAT32 file system only allows each file less than 4GB. But my some of the folders contain files larger than 4G. I don't want to manually go through each folder , check the size and then copy & paste the folders of small size.

So my question is:

What is the command for moving all the folders (including the sub-directories) less than 4GB to the new partition? Does it have anything to do with the options of mv command?

Thanks

--- Update 12/7/2014---

I ran find . -mindepth 1 -type d -exec bash -c 'f="$1";set $(du -bs "$f"); \ [[ $1 -lt 4294967296 ]] && echo mv "$f" /dest-dir' - '{}' \; >> output.txt.

The following was the first a few lines of my output:

Apple_PubSub_Socket_Render=/private/tmp/com.apple.launchd.stZBByQJc0/Render
BASH=/bin/bash
BASH_ARGC=([0]="1")
BASH_ARGV=([0]=".")
BASH_EXECUTION_STRING=$'f="$1";set $(du -bs "$f"); \\\n        [[ $1 -lt 4294967296 ]] && echo mv "$f" /Volumes/WIN_PANC/movies/'
BASH_LINENO=()
BASH_SOURCE=()
BASH_VERSINFO=([0]="3" [1]="2" [2]="53" [3]="1" [4]="release" [5]="x86_64-apple-darwin14")
BASH_VERSION='3.2.53(1)-release'
CLICOLOR=1
COLORFGBG='15;0'

They are not the folders I want to move. Am I doing right?

You can use this find command to list directories that have files greater than 4GB:

find . -mindepth 1 -type d -exec bash -c 'f="$1"; read s _ < <(du -s "$f"); \
        [[ $s -lt 4194304 ]] && echo mv "$f" /dest-dir' - '{}' \;

Remove echo before mv command once you're satisfied with the listing.

Using the following codes can do this for you (for files >4G 

#! /bin/bash
my_files=`ls --almost-all -1v -s -A --block-size=G|sort|sed -e 's#^[0-4]*G##g' -e '$ s#.*##g'`
echo "$my_files" >> my_files.txt
while read -r file; do
echo "MOVING FILE : $file"
mv "$file"  "destination_location"
sleep 0.5
done < my_files.txt
rm -rf my_files.txt

Note: change your directory to where all your files to be copied are present in a terminal, then you can run script from the same terminal. Ensure you replace "destination_location" with the directory you want to move the file to inside the codes. Afterwards execute script.

Note: You will have to change your directory and run the codes in each directory.
