hi, im trying to build something like

_http://www.filecrunch.com

one question i do have is when i upload a file to filecrunch then try to download it the url becomes something like this:

_http://www.filecrunch.com/file/~wlrnof

how would i create something like this? so far i have in my interface is the upload field and when the file is uploaded it goes to a some directory that i've specified in php.ini

if there is a book i can purchase i would get it lol. but any help would be great.

thanks from the middle of my heart.
