FIRST PROBLEM
I have to import a dataset contained in a foulder that have many sub folders.
I'll explain. I have the first folder (TEST) and I have 1000 folders inside. in each of the 1000 folders there is a .txt file (which contains the values ​​to be used as datasets). I would like to find a way to open all 1000 .txt files telling R that they are in "TEST".

SECOND PROBLEM
TEST is a .rar folder. can I import it on R without having to first unzip it?

About the reading of file within folder you could

• use fs to manipulate paths and select all the file you want to read
• use purrr to map the reading function to each element.
