file name from folder path

Hi all,

I have large datas with the folder path from that i need to seperate file names, can someone help me.
It has so many subfolders and from different location.
for example:
operator://ww/newfloder/rrdfdfd/22kdfhdi/cars.xls
operator://ww/newfloder/fdfdfdrr/22kdf/hireinghdi/duke/bikes.xls
operator://ww/newfloder/rr/10.25/truck.bat
operator://ww/new/floder/rr/10.25.145a2.bat
operator://ww/newfloder/rr/10.25.145aaaaa2.bat

i just want to seperate file names at the end...ex:
cars.xls
bikes.xls
truck.bat
10.25.145a2.bat
10.25.145aaaaa2.bat

Thanks,
