I want to rename the below files, such that the first 4 chars and last 7 chars are removed, the remaining chars to be converted to decimal, while rename.
Example if the filename is 0030002345678.txt
, should be renamed to 00.txt(removing the chars and converting to hex).
If it is 00300A2345678.txt
, should be renamed to 10.txt(after conversion from hex of '0A'
