DROPitTOme

DROPitTOme is a free application that works in combination with your Dropbox account and allows anyone to transfer you files of any kind. The maximum file upload size is 75MB and all files transferred are encrypted for greater security.

Just register to the service and then authorize the application to connect with your Dropbox account. You will find a new folder right inside your Dropbox account called DROPitTOme that will store all the files you receive using the application. All other files and folders will remain untouched.

To allow your peers to transfer large files to your DROPitTOme folder, you will get a unique upload address like www.dropitto.me/username which is password-protected. Also, you will get an email notification whenever a new file is uploaded.
