Help twrp folder not showing up

[Android Question]

Previously I was running stock android 5.1.1, then I decided to flash Dirty Unicorns. So I backed up the stock rom using twrp (2.8.6.0), flashed the DU rom with gapps. Now when I connect my device to the pc I cant find the backup neither could I find the twrp folder. The standard document viewer that comes with DU also isnt showing any twrp folder but there is a file names 'twrp' of 0b size.I tried finding similar threads but they didnt help a lot.

Update - I could not find it using Astro file manager either.

Hi

What device do you have? Where was the twrp folder (containing your stock rom nandroid file) backed up to before flashing DU?

I have a nexus 7 2013. Didnt see that before flashing I just backed it up and flashed another while in recovery.
