No vendor, application, purpose, or documented internal structure has been identified for the .crt_aq file extension. It cannot therefore be assigned to a specific file type or software product.
There is also no reliable information about supported platforms, related files, or whether this extension is still in use.
No specific program can be recommended for opening a .crt_aq file because its format is unknown. The software that created or supplied the file is the most likely program to recognize it.
Do not rename the file to another extension unless its format has been identified.
A .crt_aq file cannot be converted reliably without identifying its format and source software. If the originating application recognizes the file, use that application's own export or save-as feature.
