How to determine which files have unexpected contents.

[stromb0li]

When trying to install an add-on I'm developing, I'm prompted with a warning that I have 6 files with unexpected contents. I've generated hash values for all files, but still continue to receive the error.
1) Is there a way to identify which files contain the "unexpected contents"?
2) Is this error triggered in other ways other than hash mismatch?

There are dozens of other files in the add-on as well that are not flagged, which is sort of weird.

Thank you!
