A suggestion based on [this solution](https://discourse.julialang.org/t/rename-multiple-files-in-the-folder-with-julia/57976/2):

```julia
dir = raw"C:\Users\jrafa\CSVFILES"
cd(dir)
csvfiles = filter(endswith("pal.csv"), readdir())
for file in csvfiles
    mv(file, file[1:4]*"_"*file[5:6]*"_"*file[7:8]*".csv")
end

```
