What Is an MDW File?
How to Open an MDW File
MDW files are opened withMicrosoft Access.
See Microsoft’sWhat happened to user-level security?for some additional information on that.
For other MDW files, use afree text editorto open it as atext document.
Seethis thread at Stack Overflowfor specific instructions on opening an Access 2003 MDW file in Access 2010.
Similar steps could be taken for a version newer than Access 2010.
This is usually possible through anExportmenu of some kind.
Still Can’t Open It?
Some files look like they’re related because of how similar their file extensions are spelled.
But this rarely means that they can open with the same software.
Even though their file extensions are similar, MWD files are used withMariner Write, not Access.
This is also the case withMDandMDAfiles.
Therefore, you shouldn’t use the file that Microsoft supplies with Access but instead create your own.
