Questions & Answers
001 files: Frequently Asked Questions
What are 001 files?
The 001 extension is used for storing fax image files created on several types of devices and platforms, including Ricoh faxes and Smartfax. A 001 file can contain multiple pages or an image of the first page from a series in which the next pages use the following numbers (002, 003 etc.). The 001 format is not compatible with many image viewers or editors, so for easier handling it can be converted to more accessible extensions.
