How Do I Find Out What a DLL File Does?

Sometimes, you might want to know about a particular file; not a data file, but a particular .DLL or .EXE file. While this can be a daunting process because of the sheer number of such files, two sites exist that attempt to give you that information:

• ProcessLibrary.com

  ProcessLibrary.com is a product of Uniblue Systems Ltd. the people behind WinTasks 5 Professional, a program that gives you control over all processes running on your personal computer. This award-winning product gathers detailed information on all running processes. WinTasks then gives you simple explanations for thousands of programs - allowing you to remove useless resource hogs and security threats - in just a few clicks. The website is a Web version of the WinTasks program database.

  

• Filename.info

  Filename.info is a developing database of programs and .DLL files. Each file in the database on that site has basic information about which program owns the file, version and size information, checksum data, and other data as available.

• Microsoft DLL Search

  Microsoft also maintains a DLL search engine for all of their products. To see if the DLL file was distributed by Microsoft for one of their products, visit their site.
