There are various cases in which users face MDF access denied error and cannot open MDF File. For example, an employee creates a database of an organization and save it at the location where SQL Server is not installed, after sometime another employee, tries to attach that database to SQL Server but they got MDF access denied error message and unable to open MDF File.
In order to resolve this error, he/she try to find a way so that they can be able to attach or view the database in MS SQL Server.
