Only Microsoft Windows applications can open and run DLL files. DLL Export Viewer v.1.55 This utility displays the list of all exported functions and their virtual memory addresses for the specified DLL files. You can easily copy the memory address of the desired function, paste it into your debugger, and set a breakpoint for this memory.
EXE headers - analyze portable executable files (.exe,.dll,.drv,.sys,.etc) online and view basic header information and images / icons embedded into file. Featured stuff; Response header - view web server response headers. Learn, analyze and reduce HTTP header overhead, and as a result, increase actual payload size, to fit more data into.

Usage
listdlls [-r] [-v | -u] [processname|pid]
listdlls [-r] [-v] [-d dllname]
| Parameter | Description |
|---|---|
| processname | Dump DLLs loaded by process (partial name accepted). |
| pid | Dump DLLs associated with the specified process id. |
| dllname | Show only processes that have loaded the specified DLL. |
| -r | Flag DLLs that relocated because they are not loaded at their base address. |
| -u | Only list unsigned DLLs. |
| -v | Show DLL version information. |

Open DLL File
DLL file is an executable file which is used as 'Dynamic Link Library' or 'Application Extension'. Microsoft Windows applications can open DLL file and execute code from it. One DLL file could be shared between multiple Windows application. Also Microsoft Windows OS uses DLL files to store executable code for different windows components (graphical engine, networking, printing, etc.).
DLL is one of the most frequently occuring file extensions on your PC. Most of DLL files are located in C:WindowsSystem32 folder. Also Windows applications store DLL files in their corresponding folders in 'Program Files' and 'Program Files (x86)' folders. When you launch a Windows OS application it will look for its DLL files in the folder where you launch it from and will try to open DLL files and load them into memory.
Open DLL File on Windows
- Run application which uses DLL you want to open
- Use hex eitor like HxD, WinHex, UltraEdit to open DLL file in hex mode
- View DLL dependencies using Dependency Walker tool
- Use text editor like Sublime Text, UltraEdit, Notepad++ to open DLL file in text mode
- Disassemble DLL file using Microsoft Disassembler DUMPBIN.exe tool and review output
How to Open DLL File
If you want to check if a specific file is a DLL you can do it via following methods:
- Open DLL file with text editor or a hex editor. Check if the first two symbols in the file are MZ and the rest are binary symbols. If it is so and extension of the file is DLL then most probably it is a real DLL file.
Below is an example of DLL file opened in Dependency Walker in Windows OS.
Please note that DLL files could contain dangerous viruses that can do serious damage to your computer. Do not download DLL files from the internet and do not replace your local DLL files with ones which origin is questionable.
Applications which can open DLL files
- Microsoft Visual Studio. Visual Studio is capable of opening DLL file and viewing and editing certain sections of it like textual resources, icons, messages, etc.
- Microsoft Disassembler. It is part of visual studio but it will allow you to view DLL file in great details. It will decompile DLL from binary code to assembly instructions which are much easier to read than binary code.
