Notes:

* For images and media files, CDR doesn’t "edit" the visual content, ensuring that the original and sanitized versions maintain the same appearance. However, quality may be affected due to the decoding, processing, and re-encoding steps involved in disarming potential threats.
* When an Excel file is being sanitized, the cleaning time increases as the file size or the number of records grows. If the Excel file is very large, the process may be interrupted depending on system resources.
* MS Office files version 95 or older not supported. Only support 97-2003, 2007 or later.
