yes it is a script

you need some working links and premium account of the site from where you want to transload however free will also work but really not recommended. just put the links in RL and click transload after that you can Rename,zip,unzip,rar,unrar,split,merge the file and upload it again

yes the script is free but you have to buy a server, VPS or rapidleech hosting from someone

look into hosting offers section

its main advantage > Very High speed down | extract and compress | High Speed Upload
