FAQ
"What is the relation to KHexEdit?"
Okteta is an independent new project, with a completely different codebase and architecture, written from scratch, by a different author.
KHexEdit is discontinued for the KDE 4 series, as it hasn't had a real maintainer and the port to KDE 4 was only incomplete. Okteta is first included in the 4.1 release of KDE. So in fact Okteta is the successor to KHexEdit for KDE 4.
"Are very large files (up and larger than 1 GiB) supported?"
Not yet, as it is still subject of discussion how partial loading and the related issues should be reflected in the UI.
Currently a complete copy of the file is loaded into the working memory, so please be careful if the size of the file is close to the order of magnitude of the size of your working memory.
"What about a diff tool?"
A facility to view and work on differences between files and file versions is planned for later versions of Okteta.
