DLL Informant

DLL Informant is a small application that reveals technical information on your DLL files, so you can find out how much space they occupy on the disk, among others. It is simple to set up and use.

Toward the end of the installation procedure, DLL Informant builds a database with the dependent modules it collects; this task may take a while to finish, and you can update the database at any time.

The interface of the application is represented by a standard window with an uncomplicated layout. All DLL items imported in the database are shown in the main frame; you can check out the file path and format, usage count and registry count for each module, together with the application that uses it, and its Windows Registry entry.

You can open a DLL item straight from the main application window, thanks to the context menu, as well as disable the status bar. This list can be saved to a plain text document (TXT format) for further analysis. However, you cannot print it directly.

DLL Informant is very low-demanding when it comes to the CPU and system memory, so it does not interfere with the runtime of other active processes. It has a good response time and worked smoothly throughout our evaluation, without causing the operating system to hang, crash or pop up error dialogs. However, the app has not been  updated for a very long time, so DLL Informant is not supported by newer Windows editions.
