Have you encountered a problem with a ASD file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a ASD file here. In the further part of this page we have added a list of programs that should open your ASD file. It is enough you choose a proper application for your operating system, download and install it.


The ASD extension is used by Microsoft Word version 95 or later for auto-save files. Word stores the edited document independently at regular, adjustable intervals. Files with the extension ASD are created in the temporary directory. These files are deleted when the document is saved properly.

However, if Word did not correctly save a document due to an error or crash, this backup file can be used to restore the document. This usually happens automatically. It can also happen that this does not happen, then you can search for the ASD file and load it with Word (show all files).

How to open a ASD file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the ASD file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a ASD file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support ASD files. At this point we are looking for disk space where the application was installed in and we can link it with a ASD file. Since then, our operating system will use the selected program to support all ASD files.

Other issues

Despite the described problem with ASD there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the ASD file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the ASD file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
