Data Recovery and Disk Utilities Forum @R-TT

UDF is the abbreviation of Universal Disc Format, which was developed by the International Organization for Standardization in 1996. In Windows, its hard disk can also be formatted into a UDF file system through the Format X:/FS:UDF/Q command.
This format can support single file over 4GiB,and has more compatibility than NTFS/exFAT/ReFS. It can be applied to large file transmission of portable storage devices such as CD/U disk/mobile hard disk under various operating systems.
However, it was found that the latest version of R-Studio did not recognize the file system and did not support data recovery.

I've passed your suggestion to our developers.

I'd like to see XFS support long before we worry about UDF. I've easily seen 150-200 cases where the file system was XFS, and probably only one where it was UDF. This should be a much lower priority.
