MH is a coding standard used by some fax machines models to store sent ore received data. MH stands for "modified human" and allows fax machine software to compress the space reserved to image and text, thus decreasing the time required by transmission. MH files are probably difficult to open outside the fax machine with which they were created, so converting them is the best solution.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple MH files as once.
