Microsoft Visual Basic Setup Wizard Dependency Format | Microsoft | Developer Files |
The .DEP file extension stands for Windows Dependency File which stores required settings, dependencies and other information for any type of application created for the Microsoft Windows platform. It is associated with the Dynamic-linked library files in Windows and utilized by the system, specifically used for processor and memory management. The DEP file records the application launch path and various command line arguments used by the program.
Functionality
DEP file enables applications to draw on data stored in specific computers regardless of the environment or system. These files are used for third-party programs to run without software problems while connected to certain versions of Windows. Without DEP files, applications will be unable to access necessary resources from existing libraries within the system. In some case, files with the .DEP extension can be found within certain Windows installation kits which users can install manually.
Additional Information
Similar files extensions and their functions include .DEF, which stands for Delay Load Import Definition File; .DCF, defined as Data Definition File; .DAT, meaning Datafile; .DRV, Device Driver; .DLB, Dynamic Link Library Catalog; and .DVB, DataView Controls Resource File.
The settings, dependency requirements and other information found in a DEP file can be manually edited by a knowledgeable user with good understanding of how software works and specific application processes. However, it’s not recommended modifying this file since any mistake may lead to serious problems in using an application. Generally, there's no need to open this proposal unless users need to troubleshoot or modify the setup process for applications running on Windows.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .DEP) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .DEP extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .DEP file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .DEP extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .DEP extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .DEP file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .DEP file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .DEP file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .DEP file) will be extended to the maximum.
It is also good to check
- if the .DEP file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
