This is an easy one to code. But where do you want the file to be selectable? Like say, a directory listing and besides each file there's a link that says 'Upload to Hotfile' ?

When clicked on, it'll upload the file to your hotfile account? I can do that. Should take me a couple minutes. But, it won't show you progress. Just the download link once the upload is complete.
1.yes , it is easy code...
2. upload to my hotfile account
3.i think it is not hard to get codes form rapid leech script (it is my thinking)

^ yup as he says.. curl's a charm for that.. but no progress bar..
yes CURL is for that ....

you can use phpuploader or sBorg
not commercial or big project

if any body can code this with progress i will pay .....(please send me your price)
OR
if anybody can code this without any progress bar . i read above it is work of couple minutes i will be very thanks full for this person (if he have warez site i will post books i have great collection )
