Trick to Open A File With Unknown Extension

File extensions are important attributes for the applications which allows you to process the information existing in a certain file. Practically, a file extension is the suffix added after the dot (.) sign and the operating systems use the letters contained in the filename suffix to assign a compatible application to open the file.
For example, .txt files are simple text documents which can be opened and edited with any ordinary text editor. When you want to view or edit the content of a .txt file, the operating system will not search the type of information existing inside it: the suffix from the end of the filename is identified and correlated with an application designed for the management of .txt file type.
This is a fortunate case, because .txt files represent a common file format. The main problem is what to do when a file type unknown for the operating system must be opened.
A quick solution is provided by the file extensions databases. These websites allow users to search for a specific or desired file type (the suffix contained in filename). If your file extension exists into the database, it will be displayed alongside comprehensive information about the file type history, applications that can be used to open this kind of files and more.
When you have troubles to open a certain type of file which is not recognized by the operating system, the next websites could help: extensionfile.net, filext.com or file-extensions.org.
