To work with your data, we create a shared folder. This way there is no need to copy the data across.
To configure a shared folder the VM must be in powered off. Click on
Settings.

Then select the
Shared Folders from the top row.

Click the "Folder Plus" Button and select the Folder you like to access from within the VM. Tick the corresponding box if you like this folder to be mounted automatically.

You can add more folders if you like. Once all Folders have been specified, click
OK.
Start the VM by clicking the green
Start button and wait for the VM to boot. Log on using the triplex credentials specified before.
Make a directory that serves as the mount point, e.g.:
>mkdir ~/data
You then need to mount the shared folder:
>sudo mount -t vboxsf -o uid=1000,gid=1000 shared_folder_name /home/triplex/data
Here,
shared_folder_name is the name of the shared folder. In the example, it would be
TFO_design. Voila, you can now access your data at
/home/triplex/data
.
Important note: When running
Triplexator or
Triplex-Inspector point to the data in your mounted folder and also specify an output directory at a shared folder location as the space available within the VM is very limited.
