When you deal with dataset, sometime, the file name gets very long, and somehow produces error because of.. its very long name, of course! So, this is the code to rename multiple files by adding index number.

Long name files

Save this code as BAT-file then run this code in the same folder.

set /a Index=1

setlocal enabledelayedexpansion

for /r %%i in (makan.*.json) do ( 
    rename "%%i" "makan.!Index!.json"
    set /a Index+=1
)

Then.. what a wonderful world!

New name
