Associating file extensions with the correct program is rather easy if you know how to go about it. File extensions give you clues as to the type of file they are and the kind of program that you need to use in order to open or execute the files. You will know that a .jpeg file is an image file and that you need to use image viewer software to open such files. .Avi files are video files that need software such as Media Player to open the files. This appears easy but when your system displays the message “unknown file type” you are bound to take notice. This is because the file that you accessed is not opening for some reason. The operating system fails to identify the file type and it is therefore not able to associate it with the correct program.

However, before you download any file, make sure that you have scanned the file with an updated anti-virus before you proceed to open it. After it has been found to be safe, you will probably try opening the file. It is then that you may come across the message that the file type is unknown and get a list of programs that you can try opening the file with.

b. You just got an e-mail and it came attached with a file. You now have to determine if the mail was sent to you from a contact you trust and if not, do not hesitate in deleting it without opening it. Once you are sure the mail and the attachment is safe, you download it and when you are trying to open it, your system displays the message “unknown file type.” Read the rest of this entry »
