The generic answer to this question is to use "find" piped to "cpio -p" with more local parameters. See "man find" AND "man cpio".
The normal method is to copy the tree to the target, verify the copy, then delete the source files.
The system I'm using is a Qnap nas so i'm not exactly sure of the exact os. I can also perform any command needed from an Ubuntu 10.10 server which has the folders mounted

Hi thanks for the help. When i try this in Ubuntu server 10.10:
Code:
 
cd b/
find ./ -type f -name "*.mp3" | while read a
 do 
b=${a#??}
mkdir -p ./mp3/${b%/*}
mv "$a" ./mp3/"$b" && rm "$a"
done

i get a "mv: unable to rename no such file or directory" error for each file piped from find. Also after i run the above the directory i was working in has new empty folders for each word in any of the original directories titles. e.g if i had a folder
Code:
b/An Album By An Artist

i end up with the following folders
Code:
b/An/
b/Albun/
b/By/
b/An/
b/Artist/
b/An Album By An Artist
b/mp3/

Maybe this is because there is spaces in the directory names?

tagmp3

tagmp3(1)							    User manual 							 tagmp3(1)

NAME

       tagmp3 - manipulate ID3v1 tags

SYNOPSIS

       tagmp3 [ -n ] mode [ format ] [ file ] ...

DESCRIPTION

       tagmp3 allows you to set and remove ID3v1 tags from mp3 files. Additionaly move mode can be used to move mp3 files according to their ID3v1
       tag. An ID3v1 tag is a chunk of extra informations such as artist name, album and genre. ID3v1 tags are displayed by most mp3 players.

MODE

       show   show file's ID3v1 tag.

       set    sets file's ID3v1 tag according to format.

       move   move file to a destination based on FORMAT.

       del    remove file's ID3v1 tag if any.

       list   displays numeric music genres along with their meaning.

       -h     print a (not so) short help message.

       -v     print version and exit.

OPTIONS

       -n     Show what will be done, don't alter any file.

FORMAT STRING

       The  format  string is a character string composed of zero or more directives: ordinary characters (not %), which are not  interpreted  and
       conversion  specifications,  each   of	which results in the corresponding ID3v1 tag field substitution.  Each conversion specification is
       introduced by the character %. The following lines describes each conversion specification along with its associated ID3v1  field.  Special
       sequence %% is substituted with a single %.

       %A     Artist Name

       %a     Album Name

       %t     Song Title

       %T     Track Number

       %y     Year

       %g     Genre

       %c     Comments

format string for set mode
       For  set  mode  the format string is a list of ID3v1 fields followed by a ':' (next chars are the field value) or a '?' (ask user for field
       value)

	      example: tagmp3 set "%A:Pink Floyd %a:The Wall %t? %T?" *.mp3
	      For each mp3 of this directory, sets the artist name to Pink Floyd and the album to The Wall.  For each file ask for the	title  and
	      the  track  number.  Leave  the other fields untouched. Be aware that genre field require a numeric value.  Known genres can be dis-
	      played with the list mode.

format string for move mode
       The format string is the destination path where each field identifier is substituted with the tag value.

	      example: tagmp3 move "/home/foo/mp3/%A/%a/%T-%t.mp3" *.mp3
	      with the set example above will move all mp3 to "/home/foo/mp3/Pink Floyd/The Wall/{track}-{title}.mp3"
	      If you prefer the "flat" naming scheme, you will use something like
	      tagmp3 move "%A-%t.mp3" *.mp3

NOTES

       move mode never overwrite files.
       move mode creates intermediate directories specified in the format string. Each directory creation is to be confirmed by the user.
       ID3v2 tags are not supported so far.
       If a file can't be moved ( wrong file type, ID3v1 tag absent or blank field , ...) then it is left untouched.
       Fake mp3 (i.e. Wave file with .mp3 extension) are moved into "fake-mp3/" directory in move mode. set mode refuses to tag  them  since  this
       would add noisy artifact at the end of the song.

BUGS

       Plenty of :)
       For move mode, source and destination must reside on the same file system / partition.
