These file names are generally all the same but the numbers being completely different and I am just looking to place a ‘I’ at the start of the file name and removing the numbers at the start of it? The old name would be XS123445567_A_RT_Y 34019 and I would like to rename it too IXS123445567_A_RT_Y instead and I would have around 50 or these files names to change, if anyone has any ideas that would be amazing! Thank you again all
