how to copy part of the filename to the beginning?
ie files are named like this:
FGT_86_74_4500_ME_Riser.pdf
FGT_55_74_4501_ME_Duct.pdf
FGT_50_74_4502_ME_Shaft.pdf
i would like to copy the four digit number 4500, 4501 etc to the start so the files are named as:
4500_FGT_86_74_4500_ME_Riser.pdf
4501_FGT_55_74_4501_ME_Duct.pdf
4502_FGT_50_74_4502_ME_Shaft.pdf
This will enable the files to be sorted by their code in windows explorer.
I have over two thousand PDF files to sort through, so any help on this would be much appreciated!
