If you are a developer or you are trying to modify some application, you should know what is contained within the file and how to interpret the data. The problem is that with various applications and versions of these applications there are a lot of files that have a different structure. For example, you may have a file that contains keys and key values. But, in another version of the same application, there may be no key value pairs. The problem is that in these cases you cannot determine the difference between a modified file and an original one. And if you are dealing with files, you may not even be able to find out the version of the application or the version of the file itself. What are you to do in such a situation?

The solution is to use the tool that is capable of comparing files. The Env Checker tool is designed to compare files and determine their differences. You can use it to compare the same file from your development environment with the original from the production environment.
