External Directory Listing

[MPG Radio]

I am new and was not able to find something specific.
We have an external drive, this drive has folders, in those folders there are more folders, in the folders are videos of various formats.

Im looking to list the top level folder name and below that list the names of the files.

In excel, horizontal would be great. The idea is that we can continue to add material to the external drive which would update in the excel when open etc. when reviewed we would just make the cell with a color that would not be erased when the table is updated.

Ideally something like this? , bold being the top level folders the rest etc.
[TABLE="class: grid, width: 500"]
<tbody>[TR]
[TD]Rock[/TD]
[TD]Electronic[/TD]
[TD]Country[/TD]
[TD]Blues[/TD]
[/TR]
[TR]
[TD]Trigger-by Alborn Theory[/TD]
[TD]Moongarden-by Electric Mud[/TD]
[TD]Straight to the sun-by Brad Tucker[/TD]
[TD]You're the Reason-by Ross Seddon[/TD]

[TD]Make Up-by Listen Up Kid![/TD]
[TD]Cruisin-by Ian Sutherland[/TD]
[TD]Good Day Tonight-by Brad Tucker[/TD]
[TD]Phraseology-by The 4 Korners[/TD]
[/TR]
</tbody>[/TABLE]

If some can point me in the right direction that would be great.
