Hi,

A.K.


I have list of files in folder 

e.g p126r62_5t19880613_nn1.tif.gz 
     p126r62_5t19880613_nn2.tif.gz 
     p200r65_5t19880613_nn1.tif.gz 

and I would like to change file name to 
     LT512606219880613XX_B1.tif.gz 
     LT512606219880613XX_B2.tif.gz 
     LT520006519880613XX_B1.tif.gz 

Does any body knows how It can be changed?
