I have a set of aerial photographs (res. 20 cm, count ~ 50, total size 20GB). 

My study area is however covered by only part of them. Thus, I wish to delete the tiles I don't need from my home folder.

Is there a way in ArcGIS 10.1 how to interactively deleted the tiles which I don't use? i.e., For shapefiles it is pretty straightforward: in editing mode, 
-> select the shapefile -> select a polygons -> delete the unnecessary ones. 

I know that I can remove the tiles manually one by one, but how can I make it easier?

Do I need to firstly create a mosaics/geodatabase of all aerial photography and then delete the unused ones?

I am really grateful for any advises/tips or tutorials about basic managing of tiles of aerial photography.
