awesome, and no i did not see that section. looks promising tho, and would work great to only upload if files md5 has changed. this would work great for smaller files, but on bigger files there would need to be some other way like rsync. but i am not to sure if that would work on an FTP server.
just sent command XMD5 <filename> and it returned correct md5 so looks like this will work out great. i just need to get a list of directories and filenames and push that to an array, then i can do a foreach loop on each file and see if it exists on the server. if not then upload it. then after that i can set it up to add any new files or check md5 of existing files. and upload where appropriate. this will be awesome as a poor mans dropbox lol
