What is a .DAF file?
A .DAF file is most commonly a DupArchive Format File used for website backups. The Duplicator WordPress plugin creates these archives. They store website files, databases, and plugins in one single package.
The .DAF extension has other uses as well. It can be a Digital Anchor File created by Telecompute Integrated Systems. Some .DAF files contain daily fiscal settlement reports from Novitus printers, managed by Subiekt GT. Other uses include financial database files, chemical thermodynamics data for CHEMKIN, spacecraft ancillary data from the NASA SPICE toolkit, or compressed Shockwave Flash game files.
How to open .DAF files?
To open a WordPress .DAF backup, you must use the extraction script provided by Duplicator. You upload both the script and the .DAF file to a web server to restore the website.
Because a .DAF file has multiple possible meanings, it is difficult to know which software to use. viewer.online/daf analyzes .DAF files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
Do not rename the .DAF file extension. Renaming does not convert the file format and can prevent software from reading the data.
Verify the source of your file. If it comes from a website administrator, it is likely a backup archive. If it comes from a retail store system, it is likely a fiscal report. If you do not know the source, use viewer.online/daf to identify the actual format of your file.

Summary
Because .DAF files use the known XML format for much of their internal structure and metadata, viewer.online/daf can safely open and display them online, eliminating compatibility problems.
