During duplicate file search and processing operations, Duplicate File Detective records information about exceptional events in its Event Log.
Event log entries have three distinct severity levels:
•Error - Events that may potentially halt file search or processing, or otherwise interfere with it.
•Warning - Events that may cause problems or alter search / processing results, but do not halt it.
•Informational - Events of general interest, usually not requiring any user intervention. May potentially impact search or processing results.
Access Denied Errors
Of all the potential errors that Duplicate File Detective may log during a given file system analysis process, access denied is perhaps the most commonly encountered. It means that the underlying Windows operating system denied Duplicate File Detective access to the specified file system path.
When this error is encountered, it is important to first consider the Windows user account under which Duplicate File Detective is running. If you started Duplicate File Detective via a normal desktop or start menu shortcut, the application will inherit the permissions associated with your current Windows user account. If your Windows user account is prohibited from accessing a given file system branch, then so will be Duplicate File Detective. In such cases, someone (perhaps you or your company's system administrator) will need to alter the security settings of the file system object(s) in question in order to grant your Windows user account access to them.
On Windows Vista or later, there is an additional consideration - User Account Control (UAC). When enabled, UAC attempts to mitigate various security risks by limiting Windows user account permissions during program execution. This behavior can be at odds with your need to process duplicate files with Duplicate File Detective, which often requires a higher level of permissions. In such cases, users may need to explicitly run Duplicate File Detective as an administrative user.
