Problem
You want to determine the differences between two files.
Solution
To determine simple differences in the content of each file, store their content in variables, and then use the CompareObject cmdlet to compare those variables:
PS >"Hello World" > c:\temp\file1.txt PS >"Hello World" > c:\temp\file2.txt PS >"More Information" >> c:\temp\file2.txt PS >$content1 = GetContent c:\temp\file1.txt PS >$content2 = GetContent c:\temp\file2.txt PS >CompareObject $content1 $content2

Discussion
The primary focus of the CompareObject cmdlet is to compare two unordered sets of objects. Although those sets of objects can be strings (as in the content of two files), the output of CompareObject when run against files is usually counterintuitive due to the content losing its order.
When comparing large files (or files where the order of comparison matters), you can still use traditional file comparison tools such as diff.exe or the WinDiff application that comes with both the Windows Support Tools and Visual Studio.
