Quick question, what's this file?

I'm going to do the Twilight Hack relatively soon for the first time (currently running 3.3, didn't upgrade).

I found this file in my memory stick once I plugged it in to my SD Card Reader, and this folder appeared:

private>wii>app>RSBE>al

And inside al, I found this BIN file:

al_080510_1800.bin

I did not copy any other files yet and as soon as I opened the Removal Disk :X folder, that folder and file appeared.

Does anyone know what this does or if I even need it?

Thanks.

that is where Smash Bros. Brawl stores things like pictures, replays, and custom stages. Chances are, that's a replay.

So it isn't critical to Twilight Hack, and I can delete it?

you can keep it on there if you want, it doesn't affect the twilight hack.

just leave it there it wont effect teh twilight hack at all.
my Gfs wii had stuff from teh mii channel on it (i think... some private folder anyways) i just left it there.

if it's in the al folder of RSB? it is a screenshot from Brawl.
You can wathc it in the game or via some software
