You can create your own directories here and place data inside. By default others can read the directories you created here, but not write in them. If you need any special permission let us know via it-support@idiv.de. To directly jump to another directory select the *Files* pane and click on the three dots (…) located on the right hand side of the current file path. Now enter the path you want to browse, e.g. `/data/`. Additionally there should be a symbolic link in your home directory called data, which points to the /data directory.

Please note that R is able to work with compressed files. This is especially useful if you are the typical csv/txt file user. Those files usually contain highly redundant data. Therefore compression can be very effective, e.g. the file which triggered me to write this was a txt file of 4 GB the gz compressed file had 98 MB. Many tools to read or write (e.g. read.table, fread from data.table) allow transparent use of compressed files, i.e. you just specify the compressed file instead of the uncompressed file.

You will be asked to enter your password again and afterwards your network home will be available at `~/winhome`. However, it will only stay connected until you log out or quit your current session. If you have any longer running jobs you might want to consider either moving stuff from the ~/winhome to /data or open a [tmux](tmux.md) session from which you detach (Ctrl+b, d) before you disconnect.
