I would like to know how to copy files with common names and paste them into another folder.
For example, I have folders f1, f2, f3 … f50. Inside each folder, there are files named a#, b#, c#…z#. # is a kind of random number and they are different in f1, f2, f3 … f50.
I would like to copy, for example,
a files from all 50
f folders and paste them into a new folder.
Could you help me to do this?
