.DL_ is a type of .DLL file format. This file format is compressed version of Microsoft Dynamic Library file.
The compression is done by a specific utility which supports compression of .DLL files. Generally .DL_ file type is used for backup purposes. As a specific DLL file is compressed and saved, it makes it easier for the user to download or share it as it takes much lesser space than original file. In order to access the data stored in .DL_ file the user has to first decompress the file and convert it into DLL with the help of utility.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .DL_ file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DL_ file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DL_ file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .DL_ extension. Directly on this website you can find a solution of the most common problem with the .DL_ file – that you do not have on your computer the appropriate program to open the file.
