IUP - Fritz Update File is a file extension that anyone can download online free of charge. It is mainly used for Fritz. If you already own this software program, then this file extension can add a little bit of extra assistance.
The file extension is relatively handy because it consists of data that upgrades the software from one version to another one. It really comes in handy when you need it the most. It is a software update file just for playing chess. Everything is downloaded automatically, so you will not have to do anything manually. You will be able to apply any changes manually, only if the Fritz program itself is not automatically updated. You will then have to install the IUP file in order to install the updates on your own. It is a very simple process to follow. You will also be able to place it right in the Fritz directory and then run the program from there. It is all going to be included right within the software installation.
You can only benefit from this file extension if you already have the program installed on your computer otherwise it will not do you any good.
