The File-Access-Plugin allows a read-only access to the SD-Card of a compatible device:

On the left side of the main window the directory tree of the SD-Card is shown. With a double click on an entry or a click on the plus-icon this folder is openend. The content of this folder is shown on the right side of the window.
A file can be transferred to the PC with a double click on the file name. The storage location is selected with the file save window.
If the selected file is a snaphshot, this file can be either saved in the snapshot-format (*.snp) or in a textual comma separated values format (*.csv).
This conversion of snapshot files can also be done for already saved files with the "convert" menu item.
