I have a folder of 1000 files and some of them belong to each other, which means that their name starts similarly such as:
20170821.pdf; 20170821_02.pdf, 20170821_03.pdf, 20170820.pdf, 20170820_02.pdf etc.
I am able to get the name of the latest file with File = new DirectoryInfo(myPath).GetFileSystemInfos().OrderByDescending(function(fi) fi.CreationTime).First()
but I need to do a comparison with the next file if it has the same name in the beginning. Can you please help me?
