Dear Tutor,
I want to change the name of the folders and the files in the tree.
All those folders and files starting with name string '---'.
Examples:
If a folder name is : \---DAT1
I want to change this to: \changedDAT1
If a file name is: \---00001.txt
I want to change this to: \changed00001.txt
I have attached the code and output to this email.
Specifically, I like to provide correct syntax (dst / destination) for line 6
code block below!
I have not understood the syntax.
Thanks in advance, for your help .
best,
banda
