Invalid file extension

The file extension you are searching for is not a valid file extension.

The file extension you supplied is invalid. It must e.g. not contain special characters like ", *, :, <, >, ?, \, /, | or spaces. It must also be less than 20 characters long.

What is a file extension anyway

File extensions are used to help Windows find and launch the correct program when you click on a file. For example, if you click on a .PDF document, Windows will automatically launch a PDF viewer if you have one installed.

Software that will open, convert or fix your files

First of all, you should rename your file so it does not contain invalid characters, and then try opening it with a generic file viewer to inspect its content. In that way you may be able to determine what type of file it really is.

Try a universal file viewer

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.

Try a system cleanup and repair

Has your PC started running slow or acting up lately? It could be that your system registry has become cluttered and contains a lot of unused or damaged data. We recommend that you run a free scan with Registry Cleaner Pro to see if your system is in an optimal state.
