Problem points

Maildir implementation in KMail

It is to be expected, that the maildir implementation in kmail does not work on Windows' file system, since it uses the ":" character in file names. It also relies (as does maildir in general) on the atomicity of making a hardlink and then unlinking the original, to implement an atomic move. The implementation used by akonadi (kdepim/maildir) relies on QFile in that regard, but it's unclear if rename is atomic on all platforms.

• jstaniek 12:50, 7 January 2008 (CET): Hard/soft links could be handled on Windows by altering the source code so that the "link" file is a text file itself and contains the target path. If we need atomic renames, Windows apparently lacks them, I have found a pre-Vista blog which contains description on how to perform them in a messy but honest way (look at the very last "Write process (on Foo.txt)" version). There's also a way to recover from application/system crash during the pseudo-atomic operations (see the very last "Recovery from a crash during write" checklist).

Integration into the Windows Explorer & Desktop

Detecting whether KMail is the default e-mail client

This shall be also reused by others for KOrganizer and Konqueror. The solution is relatively simple modifications to the Windows Registry.

Drag&drop support

Support drag&drop from/to composer and from received mails into the file system (Windows Explorer and the Desktop)

Copy&paste support

Support pasting files copied (in Windows Explorer or the Desktop) as attachments.

Notes

• The Windows port currently happens in branches/work/kdab-post-4.0 branch (kdepimlibs, kdepim modules), so it is better to check out this and not trunk directories. The branch is merged from time to time with the KDE trunk.
