How to open DEP file?

An often recurring problem with Windows Dependency Format is that DEP is not associated with the correct program file. This causes the file DEP to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the DEP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft Office

The first step is to check if the computer has the Microsoft Office program installed. The easiest method is to use the system search engine by entering the program name Microsoft Office in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file DEP with Microsoft Office. Below is a list of programs that support the file DEP.

Programs to open DEP file

Remember to download programs supporting DEP files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft Office with DEP files

However, it may happen that the application itself does not cause the DEP file to open in the Microsoft Office application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Microsoft Office application as the default for handling the DEP file.

Step 3. Update Microsoft Office to the latest version

If, despite the association of the Microsoft Office program with the Windows Dependency Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Microsoft Corporation website or update the program from the application.

Step 4. Check for the following problems with the DEP file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to DEP files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file DEP or the program directory. Sometimes virus-infected DEP files cannot be recovered, so make a backup in advance.
Older version of DEP file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged DEP files. You can restore the file from a backup or use Microsoft help.
The program can also signal the fact of encryption. The encrypted file DEP except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move DEP to a different directory.
This can happen on a file that does not support multiple access. In this case, the DEP file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file DEP to close. However, some background programs may block the DEP file while scanning. If this does not work either, restart the device.
