DLL Toys is a suite to find unused DLLs to delete, to view dependencies of executables, and to view running processes and modules. DLL Toys consists of Import Checker, a program to investigate used dynamic link library (DLL) files by executable files in your hard disk and find out which are necessary and which are unnecessary. It can also delete unnecessary DLLs. EXE Viewer displays reference DLLs and functions for selected executables as extended property sheets of Windows Explorer. Backup Manager manages DLLs deleted by Import Checker. Process Viewer displays information about running programs and used modules.
