This no doubt rather simple but I just can not get my head round this
I have a folder where jobs are arriving, file name examples below:
104774-Newsletter-Sheet-1.pdf
105323-Leaflets-Sheet-1.pdf
107929-Programme-Sheet-1.pdf
107929-Programme-Sheet-2.pdf
I need to Assemble the 4 files into 3 Folders, ie the Jobs with the same Job Number are matched and put together, jobs with just one file to be kept on their own
Any advice please would be appreciated

Thanks
