Changes since 0.4.0
- Fixed error while creating new file with Word 2003. issue

- Set DeleteOnClose flag in CreateFile when the file is already marked as deleted. JimR reported

Happy holidays!

Dokan library 0.4.0 x64 version has just been released.
This is the 64 bit version of Dokan library, which I released last week.

Dokan library 0.4.0 has just been released!
I’m pleased to announce the launch of new version of Dokan library. I completely redesigned the driver event handling model. There are a lot of improvements from the previous version. You must recompile all programs which use Dokan library because dokan.h is changed and this version is not compatible with the previous one. You need to update Dokan.NET, Dokan Ruby and Dokan SSHFS.

The license of Dokan driver is changed to LGPL from GPL.
- driver (dokan.sys) : LGPL
- dll (dokan.dll) : LGPL
- mounter, dokanctl, mirror sample : MIT

Dokan API is changed.
The difference of dokan.h is here
I changed to pass DOKAN_OPTIONS (which is passed to DokanMain) in DOKAN_FILE_INFO structure
and I put GlobalContext in DOKAN_OPTIONS structure. I add “DeleteOnClose” in DOKAN_FILE_INFO structure and changed the usage of Cleanup, DeleteFile and DeleteDirectory.

You should not delete file on DeleteFile or DeleteDirectory. When DeleteFile or DeleteDirectory, you must check whether you can delete or not, and return 0 (when you can delete it) or appropriate error codes such as -ERROR_DIR_NOT_EMPTY, -ERROR_SHARING_VIOLATION. When you return 0 (ERROR_SUCCESS), you get Cleanup with FileInfo->DeleteOnClose set TRUE, then you delete the file.

Changes from 0.3.9.
- Fixed: error during multiple file deletion. issue
- Fixed: excel support issue
- Fixed: file deletion in Explorer issue
- Fixed: improper CloseHandle issue
- Supported: filesytem wide context issue
- Fixed: 0 byte read issue
- Fixed: saving new file in notepad issue

x64 version coming soon.

I’m now preparing to launch the next version of Dokan library.

There are a lot of improvements from the previous version. I changed many parts of the driver especially communication between the driver and the user mode library. This makes Dokan much stable and removes some deadlocks. I also add some new features. If you are interested in the detail, please check the subversion repository.
Please be careful if you use the above files. They may crash your computer.

I’m planing to change the API to fix Explorer file deletion problem.
API changing requires to re-compile all other application that depends on Dokan library, such as Dokan.NET and Dokan Ruby binding. I need more tests because I changed a lot.

All the libraries will be launched in a week.
Thank you for many comments and bug reports.

2008/12/09 Update:
The next version of Dokan is almost done. I updated the repository. From this version, the license of Dokan driver is changed to LGPL from GPL. Dokan API is changed. DOKAN_FILE_INFO structure, DOKAN_OPTIONS structure, DeleteFile, DeleteDirectory and Cleanup are changed. Please re-check dokan.h file. I’m still investigating the existing issues and I hope to launch the new version in a few days.
