File Explorer

The File Explorer tools provides the means to navigate graphically around the file systems accessible from the HPC Gateway platform. It is also the entry point for exchanging files between the client device and the clusters controlled by HPC Gateway.

To open the File Explorer window in the HPC Gateway desktop click the start button in the toolbar and select File Explorer from the list.

In most respects the HPC Gateway File Explorer behaves like other explorer tools in normal client desktop environments. Directories can be navigated in the left pane. Selecting the name will display the directory contents in the right pane, or any sub-directories can be unrolled by clicking the arrowhead next to the higher-level directory name. The relative size of these panes can be adjusted by dragging the separator.

The tree of directories and files shown in the File Explorer is created from filesystems that are mounted on machines identified to the HPC Gateway by the framework configuration. Within a single File Explorer window it is possible to see multiple filesystems, and even filesystems from different machines depending on the architecture of the HPC Gateway global platform. Files can be moved identically (cut, paste) within a single filesystem, or between filesystems and/or machines. All accessible machines are listed under the Clusters label in the left-hand pane.

Also in top right pane:

  • Favorites list where selecting a favorite will directly expand then open it. Further directories can be added as Favorites by selecting from either pane.
  • Hidden files button that displays or hides hidden files
  • Refresh button that refreshes the explorer windows then reflects the last file & folders changes.

The files and directories that are displayed and accessed are governed by the underlying operating system (Linux) permission structure. Permissions flags are shown in the Authorization column of the file display.

A right click within the File Explorer panes reveals the various actions that can be performed on the file or directory.
This is an example of actions for a directory.

The actions available depend on the context of the selection.

Text files can be edited on the cluster filesystems using the in-built Notepad editor. Opening a file launches the Notepad tool on the selected file.

File editing actions are:

  • Open a new file
  • Save file
  • Save file as
  • Close all files
  • Select language mode

Notepad can also be opened from the Start menu directly.
