My brain is actually a little blocked in a strange situation... We work with CBFS and i'm now to bring the "save" function from word to work properly. I did this once before with Dokan but now i'm stuck with CBFS.

Following happens:

1. Word creates the "real" file: lets say 123.docx
--> is intended, works fine
2. Word deletes this file
--> is intended, works fine
3. Word calls multiple times for 123.docx
--> is intended, always returning "File does not exist" works fine
4. Word tries to create a temporary file, filename begins with "~WDR0"
--> is intended, works fine
5. Word calls SetAllocationSize, SetEndofFile and SetFileAttributes for this temporary file
--> is intended, works fine
6. Word calls to delete the temporary file
--> not intended,since it should write into now into the temporary file ;(

With procMon I can see, that writeFile was called out of word once, but ended with "unsuccessful" --> it never reaches my callback funtion! I think because of this, it wants to delete the file, to undo all.

Any suggestions in this issue would be glad!

Please first of all try the same with our samples, namely Mapper and VDisk (please try Mapper first) and see if the problem occurs.

Based on report from your colleague, there can be some third-party application (eg. antivirus) which intervenes into saving process. See previous post from Tran.

Sincerely yours
