easy does it...

its a well laid out interface.. the test option shows you how your data will be renamed. advanced options are handy and give you a decent amount of options.
for example if you have files vacation_number_1, vacation_number 1a, vacation_number1b .. using the advanced option, you an rename these to Spain001 by replacing vacation_number with the string "Spain" an the programs will increment the number on each successive rename.
cheap and cool.
