Unknown file extension

The .xls_aq file extension is not associated with an identified file format or software application.
The contents of an .xls_aq file therefore cannot be determined from the extension alone.

No documented vendor, application, or standard format is currently associated with the .xls_aq file extension. It may be a file created by a specific application, a renamed file, or a file with an uncommon or proprietary format.
Because the format is unidentified, its contents, structure, platform availability, and current status cannot be established reliably.
There is no known program that can be recommended for opening an .xls_aq file. The application or device that created the file is the best source of information about how to open it.
Do not rename the file to another extension unless its original format is known, as changing the extension does not convert the file.
An .xls_aq file cannot be converted reliably while its format is unidentified. Conversion requires a program that recognizes the file's actual contents.
