The financial management software Quicken uses the extension QIF for files in its exchange format (Interchange Format). These files contain specially formatted ASCII (American Standard Code for Information Interchange) texts.
Although the format is designed by Intuit, it is open, so it is used by banks to provide data on account activity.
Quicken exists in several editions that do not all support this format. Other applications, such as Corel Quattro Pro, can import the data.
The online application Mint.Com can also handle these files.

This may happen because no default application was associated with this type of files. To associate QIF files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file.
