1.1 Precautions

Use this service as a file transfer tool.

The service does not offer a file sharing server and is not intended to provide users’ shared folders for long-term file storage/archiving.

2 Supported users

All faculty and students with an account for the School of Science authentication system can use the file transfer service.

3 Required environment

The service assumes that the user certificate for the School of Science account has been installed in the Web browser. If this requirement is met, the service is accessible from anywhere and allows file uploading/downloading via the browser.

The service can be used to exchange files with those with no School of Science account through Web Publication of a file/folder.

※For Mac OS users

The service does not support Safari due to a certificate authentication bug.

We apologize for the inconvenience. Please use another browser, such as Firefox.

4 Preparation for use

4.1 Faculty without a School of Science account (thin client users)

The setup for the service will be done by the Information Technology Team. Apply to the Information Technology Team for the setup. No specific application form is prescribed; just notify us of your intention to use the service.

4.2 School of Science account holders

Access authentication is performed by using the same user certificate as for Wi-Fi authentication. The file transfer service requires no other special procedures.

※For the user certificate, see the page School of Science account. Note that the service does not accept a guest certificate for Wi-Fi (the guest certificate does not have Wi-Fi access to subnets within the School of Science).

Make sure that the user certificate is installed in the Web browser.
The installation procedures differ depending on the Web browser.

Users of Firefox, Google Chrome, and Opera should click here to review the procedures.
Access the following URL via the Web browser.
https://sendfile.s.u-tokyo.ac.jp/
Once the account information contained in the user certificate is confirmed, the user is automatically logged into the service.
The user’s private folder is created under the TOP folder. The user can work in the folder.
