UDF file system facts 

In 2021 we funded a fsck_udf command to recover corrupt UDF file systems, which was completed by reinoud@.

UDF's important because it's open and patent free. It's usually used on DVD/BR, but it can be used on anything else too.

It supports Unix permissions, unlike FAT. Unlike exFAT, it's patent-free for everyone, not just Windows and Linux.

Most OSes support UDF 1.02, but in NetBSD we support R/W up to version 2.60.

Consider formatting your shared drives with UDF. 😃


UDF file system facts 

@netbsd that’s really useful information. does UDF handle forward compatibility? Eg does a system with UDF 1.02 know how to read/write disk created with UDF 2.60?
