What is a DL_ file?

A DL_ file is a compressed .DLL file created by Makecab, a Windows utility used for compressing files and creating .CAB files. It is often used for storing DLL files on Windows installation CDs so that they take up less space on the disc.

More Information

DL_ files can be created using the following Makecab syntax:

makecab myfile.dll

DL_ files can be decompressed back to their original DLL file using this command:

expand myfile.dl_ myfile.dll

NOTE: Makecab can be used to create a compressed copy of any file. For example, an .EX_ file can be created from an .EXE file.
