How to Open DLL Files & Programs in Microsoft
DLL files are used in conjunction with other programs as valuable resource files, but they can be opened independently for customization. Additionally, other executable formats, like EXE or ActiveX Controls, can be opened for individualized viewing. Once opened, you can rewrite DLL or other executable files to begin to diagnose problems, track usage and identify associated resource files. Opening a DLL or other program-based file requires special software, as general Windows operation is not intended for coding. With proper software purchases or downloads, you can see what is written in a DLL file with a simple click.
Free Software for Opening DLL Files
Download the most recent version of Resource Hacker. Despite the name, Resource Hacker is legal freeware---it is used for hacking into your own files; it is not used for illegal third-party hacking. Resource Hacker is a free download. The file is well reviewed and is not known to have major bugs or glitches; the application received a perfect "Stability" score at Soft32.com, a well-known downloading portal.
Install Resource Hacker by unzipping the file and clicking on the "Install" icon within the now extracted ResHack.zip folder. If you do not have a program for unzipping files, download a trial or paid version of WinZip.
Open Resource Hacker and select the DLL file you wish to open. Use the Resource Hacker interface to look at the various file components. Resource Hacker will be able to open most DLL and program files, but editing capabilities are somewhat limited. If you simply need to open up a file, Resource Hacker will work, but to do more advanced operations, paid downloads are necessary.
Paid Software for Opening DLL Files
