HQX - BinHex 4.0 Encoded File is one of the best text files around. It was specially created for any type of MAC systems. There are different types of data that are within these types of files which can be compressed and taken out for use. They are in different formats as well. You will also find that this comes in handy when you want to import and export different pictures and even documents. You can do all of these things right into a single email attachment. Transferring data doesn’t take long at all using this format. There are other formats you can use, but they may not be as good as this one because they will take up a lot more disk space than usual.
