Opening ADM files
Did your computer fail to open an ADM file? We explain what ADM files are and recommend software that we know can open or convert your ADM files.
What is an ADM file?
Files that contain the .adm file extension are most commonly associated with Microsoft Group Policies. The ADM files are template files that describe where the registry policy settings should be placed in a user's Windows registry and what the interface will look like when an admin uses the Group Policy Object Editor.
The .adm file extension is also used by the Portfolio Admin-Level Access utility. These ADM files contain flag files that are used by system admins. These files are created when an Extensis Portfolio Catalog or .FBD file is opened in admin mode on a user's computer. These files are normally deleted automatically when the catalog is no longer in use.
Software that will open, convert or fix ADM files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
