Exchanging of Large Files Service
Developed by Information Technology, Exchange of Large Files (ELF) and Secure Exchange of Large Files (sELF) that allows the RU community to send and receive large files over the Internet using a standard web browser such as Firefox and Internet Explorer. Both services exchange files similar to using a web-based FTP (file transfer protocol) client to move files to and from a location. Anyone with a rockefeller.edu e-mail address can login and use either service. RU users can request a guest account to be created to be able to receive a file.
Exchange of Large Files (ELF)
Users who need to send or receive non-sensitive files may use the regular ELF system which allows a user to send with a total combined size of 2GB. For additional information about ELF, click here.
Exchange of Extra Large Files (xELF)
Users who need to send or receive non-sensitive extra large files may use the xELF system which allows a user to send files between 2GB and 20GB size. Having java preinstalled is required. For additional information about xELF, click here.
Secure Exchange of Large Files (sELF)
Users who need to send or receive sensative files, such as social security numbers, credit card numbers, drivers license numbers and similar information, need to use sELF to send/receive the files as sELF will encrpyt the file(s) to make the transfer secure. Users may send files upto a total combined size of 500 MB. Users will need to provide a passphrase when sending the file and provide the passphrase to the recipient. When retreiving the file(s), the recipient will be required to enter the passphrase for each file being downloaded and provide the passphrase to the recipient seperately as it will not be included in the sELF Alert e-mail that is automatically generated. Users who do lost the passphrase will need to reupload the file(s) and specify a new passphrase as there is no way to recover the passphrase. For security, if an incorrect passphrase is entered when downloading the file(s), the file will not download correctly. For additional information about sELF, click here.
