Thanks for reply.
This definitely sounds like a permissions issue?
Following is file permission. This file is located in my home directory
-rw-r-x--- 1 toushi users 645120 May 16 18:25 Copy_V3_Analog_.ppt
I checked didn't found any file permission issue. If the same kind of file copy on other users home directory and change the permission and ownership accordingly.It work for that user he can edit and save the file.
How exactly are you mounting your share?
Ans:-From Windows7->Mycomputer->map network drive (GUI)
