Big Problem for me

[wakrajci]

Forgetting the power of BRU, I hastily deleted the 1st letter of folders in a very large array. I did not discover it for a few days later.Thankfully the files in the folder have the same name. The folder contains about 4000 folders with files in them. I have been working on this problem for a while, and I can't seem to get it right. I want to copy the 1st letter of the file in each folder and add it to the beginning of the folders name:
Example: ape Fear (1991) --- Cape Fear (1991).mkv --- Cape Fear (1991).
A File in that folder

Please help!!
