Nice !!

Buy a license and simply put the portable files in your flash drive. If you want an icon on the menu, just drag the XYplorer.exe file onto the LiberKey menu and then drag to whichever folder you want (I put mine in File Management > Manager).
That's what I did, and it works splendidly.

There isn't an auto-update feature, but it really isn't that hard to every so often check for updates from XYplorer itself, and should there be an update, it is as simple as dragging the new files into the original's directory.
