Crocofile is a simple PHP script to easily upload and download files to and from password protected areas. It was created as an easy way for a small company (or freelancer) to exchange files with customers. No more abusing email or trusting external 3rd parties.
Crocofile's use of modern HTML5 upload technlologies makes it easy to upload many files at once and it also supports drag'n'drop uploads.
