Does DMF use metadata to detect similar media?
No, our software doesn't need to, as it is based on the comparison of intrinsic file data. This method is far more reliable than the use of metadata, that remains uncertain and leads to the detection of false positives.
Is it possible to transfer my license to another computer?
Yes, Although licenses can only be activated on one computer at a time, it is possible to deactivate your license on one computer to activate it on another. The only issue is that you have to wait for 30 days before carrying out the computer transfer.
