Topicbox-Message-UUID: 075349ee-ead8-11e9-9d60-3106f5b1d025 from the wikipedia article: http://en.wikipedia.org/wiki/ExFAT Microsoft has not released the official exFAT file system specification, and a restrictive license from Microsoft is required in order to make and distribute exFAT implementations. Microsoft also asserts patents on exFAT which make it impossible to re-implement its functionality in a compatible way without violating a large percentage of them. the article links a pdf with some reverse engineered info. that should be enougth to implement it. the principle is the same as fat. but its not clear how one can get this license from microsoft. -- cinap From mboxrd@z Thu Jan 1 00:00:00 1970 MIME-Version: 1.0 In-Reply-To: References: Date: Sat, 12 Jan 2013 01:15:44 -0200 Message-ID: From: =?UTF-8?Q?Iruat=C3=A3_Souza?= To: Fans of the OS Plan 9 from Bell Labs <9fans@9fans.net> Content-Type: text/plain; charset=UTF-8 Subject: Re: [9fans] a disk filesystem for both Plan 9 and Linux?

I don't think anybody's fixed that. Newer extN filesystems have a configurable inode size (the superblock says what the actual size is). I have a patch to deal with this, but it's not very thoroughly tested. Contact me if you want it.

Sorry it doesn't fix the directory-indirect-block bug.
