I neeed one more solution for replacing a few characters in a file name. As I mentioned above, my folder structure and files are constructed as given in my previous posts.
Code:
folder years -> folder months -> folder days
In each day folder , there will files, and their file names are as mentioned above posts
Now I have to loop through each folder sequentially like year 2009,2010,2011 etc..and go in days folder and modify file names. from March 2011 to 26 jan 2012

Out here ; assigning 7111 to very first file and then incrementing by one to next files
It means ; I am looping through each file and replacing the character between id000 and _t to 7111 and incrementing by 1 sequentially.
