Transferring Data to Midway

This page provides information on how to transfer data to Midway from your local computer (and vice versa). The following table summarizes available data transfer methods and what tasks they are suited for:

Transfer Method
Suitable For Not Suitable For
Secure Copy (SCP) Transferring a few files less than a few GB. Terminal users. Transferring large files or numbers of files.
SAMBA Transferring a few files less than a few GB. Desktop GUI users. Transferring large files or numbers of files.
Globus Transferring large files, datasets, and multiple directories. Quick transfer of few files.
HTTP Sharing data publically via web with collaborators. Sharing data with large number of users. Transferring data to Midway via HTTP is not possible.

Secure Copy (SCP)

macOS and Linux systems provide a scp command which can be accessed from the command line.

To transfer files from your local computer to your home directory (see Data Storage for information on directories), open a terminal window and issue the command:

For single files:

scp <some file> <CNetID>
scp <some file> <CNetID>

For directories:

scp -r <some dir> <CNetID>
scp -r <some dir> <CNetID>

To transfer to a directory other than your home directory (for example, project):

scp -r <some dir> <CNetID>
scp -r <some dir> <CNetID>

When prompted, enter your CNetID password.


SAMBA allows one to connect to (or “mount”) their home and project directories on their local computer.

This method of accessing your RCC home and project space is only available from within the UChicago campus network. From off-campus, you will need to first connect through the UChicago VPN.

Connecting from Windows

Map Network Drive

On a Windows computer, select “Map Network Drive” and enter one of the following UNC paths depending on which location on Midway you wish to connect to:


Enter ADLOCAL\CNetID for the username and enter your CNet password.

Connecting from macOS

Connect to Server

On a macOS X computer, select “Connect to Server” (from "Go" dropdown in Finder) and enter one of the following URLs depending on which location on Midway you wish to connect to:


Enter ADLOCAL\CNetID for the username and enter your CNet password.


While transferring large files and/or datasets over SAMBA may be appealing, it slows file transfer for all other users. Please use Globus for large transfers.

Globus Online

Globus Online is a robust tool for transferring large data files to/from Midway. RCC has a customized Globus Online login site.

  1. Go to and Select “University of Chicago” for the existing organizational login:

There is extensive documentation on the Globus Online site as to how to transfer files in different modes. Please refer to their documentation for more details or contact us with any RCC specific issues.


Midway2 only

Please note that HTTP-based data sharing is currently supported on Midway2 only.

RCC provides web access to data on their storage system via public_html directories in users’ home directories.

Local path Corresponding URL

Ensure your home directory and public_html have the execute permissions. If the folder public_html does not exist, create it. Optionally, ensure public_html has read permissions if you would like to allow indexing.

You may set these permissions using the following commands:

chmod o+x $HOME
mkdir -p $HOME/public_html
chmod o+x $HOME/public_html
// optional; if you would like to allow directory listing.
chmod o+r $HOME/public_html
Files in public_html must also be readable by the web user, "other", but should not be made executable.

You may set read permissions for web users/"other" using the following command:

chmod o+r $HOME/public_html/research.dat


Use of these directories must conform with the RCC usage policy. Please notify RCC if you expect a large number of people to access data hosted here.
