CryptoSearch

CryptoSearch is a streamlined and no-nonsense piece of software designed from the ground up to make it as straightforward as possible for you to locate and find encrypted or password protected files on your computer or any local network.

Comes with support for a wide array of encrypted files

The utility does not rely on scanning the file extensions, but rather it analyzes all the files individually to determine if they are indeed encrypted or not.
Having said that, you should know that CryptoSearch is capable of locating password protected of encrypted Microsoft Office-specific files (Word documents, Excel spreadsheets,  PowerPoint presentations, Access databases, and Outlook mailboxes included), PDFs, as well as various archive types such as ZIP and RAR.

Does not require installation but it is dependent on the presence of .NET Framework 2.0

Since it does not require installation, you can get started with this lightweight app in practically no time, by launching it via its associated executable file.
However, please take into account that the application requires that .NET Framework 2.0 is present on your computer's system in order to work as intended.

Identify encrypted files from multiple sources and combine the results into single reports that can be easily be exported

The interface is exactly as you would expect from such an application, non-impressive yet quite intuitive. We should point out that the app allows you to search for encrypted files in one or multiple locations at once, which means that it can thoroughly combine the results into a single report.
Since we are on the subject, please note that CryptoSearch provides you with the possibility to export the comprehensive reports as plain text files or as HTML files.

Locate encrypted files with no more than a few mouse clicks

All things considered, CryptoSearch is a very efficient solution for locating various password-protected or encrypted files on your computer's hard-drive or local networks.
