A Few Minutes Can Save You Hours of Frustration

The Problem

You received or downloaded a file which Windows does not recognize. When trying to open the file, you receive an error message titled "Open with..." The two most common reasons that prevent your PC from opening files are 1) missing or improperly installed software applications and 2) file extension errors. A file that has no extension or that has an extension that is not listed in the registry on your computer will need to have some program associated with its type before it can be opened or used.

The Solution

The Open File tool has two functions that you can take advantage of with a single scan. First of all, if you are having issues opening a file, you can use the Open File tool to scan for issues for this file type. These include a missing host application or having an improperly registered file type in the system registry. Secondly, if these issues are not detected, it could be that you do not have the necessary program installed to support operations associated with the file. PC TuneUp Maestro can recommend a program that you can download and use to support that file type. At the same time, the Open File scan will also identify other file extension type errors and the results are displayed revealing the issues and providing you options to correct for them.
