What is a DL_ file?
DL_ is the extension given to files that are associated with Microsoft Windows operating systems. DL_ are files that are backup files for system link libraries dynamically saved in DLL files. This solution is often used in software distribution, because DL_ copies are compressed, which saves space on the data carrier. Also, if the DLL is damaged, you can restore it with a DL_ copy.
Compression of DL_ files is based on the CAB format. Such files can be generated and unpacked using the makecab command in the system console.

How to open DL_ files
If you cannot open the DL_ file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports DL_ among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the DL_ file can be found in the table. Now just download and install the appropriate application.
Possible problems with the DL_ format files
The inability to open and operate the DL_ file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Microsoft Windows DLL Backup Format file. Below is a list of possible problems.
- Corruption of a DL_ file which is being opened
- Incorrect links to the DL_ file in registry entries.
- Accidental deletion of the description of the DL_ from the Windows registry
- Incomplete installation of an application that supports the DL_ format
- The DL_ file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the DL_ file.
- Drivers of equipment used by the computer to open a DL_ file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the DL_ file should operate with your programs without any problem. If the problem with the DL_ file has not been solved, it may be due to the fact that in this case there is also another rare problem with the DL_ file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.DL_) you have two ways to do it. The first and the easiest one is to right-click on the selected DL_ file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the DL_ file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. DL_) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
