I was recently asked come up with a process for generating MD5 Hash values for a list of files. That wasn't too difficult but problems arose when the file size was larger than about 200M. I found some code here to work around that until the file size exceeded 2G.



After a pretty extensive Google search and some modifications to a couple of seemingly complete class modules found on Stack Overflow, I have come up with a process that appears to handle very large files (at least a large as the largest file I have had to process > 3G).

The problem is that classes were apparently written around 2005 and all of the declarations are 32 bit. I was hoping that some guy or gal here with a 64 bit installation of Excel would take interest and see if they can modify the conditional If statements so the code will function in both 64 and 32 bit applications. Here is the code in three sections

Here is the file: Declarations Need Help.xlsmDeclarations Need Help.xlsm
