The PDM file extension stands for Visual Basic Project Information File, which is associated with the Microsoft Visual Basic software. It is a simple text-based file that stores the information related to a logically grouped collection of component files with their associated source code. This includes the paths to include files, screens, modules, resources and class modules.
Technical Details
The PDM file is created for projects that were written in a previous version of Microsoft Visual Basic. It provides information that was originally stored in the .DSL, .DSA, .DSW, and other similar files created by older versions of the basic software. It also contains metadata about the projects and references to components such as forms, made in the basic language.
Similar File Extensions
Other similar extensions include .VBP, .VBW, .VBG, and .FRM.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .PDM) 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 .PDM 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 .PDM 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 .PDM 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 .PDM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .PDM file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .PDM 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 .PDM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .PDM file) will be extended to the maximum.
It is also good to check
- if the .PDM file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
