Help with default textures

Hi,I am designing a texture make-over for FS9 (Realitypack series) but cannot remember the file name a particular texture which is bugging me. Does anyone now of a toolwhich displays the file names of textures (in FS or out) for a particular area? I vaguely recall seeing something like that a long time ago but have not been able to findit anymore!Any help would be greatly appreciated.Thanks!Sascha
