Save log file to "all user\application data\"

[squidge]

Check the Microsoft requirements on MSDN. Eg for Windows 7:

"All application data that must be shared among users on the computer should be stored within ProgramData. All application data exclusive to a specific user and not to be shared with other users of the computer must be stored in Users\<username>\AppData."

As for where the directories are, check out QDesktopServices::storageLocation

I used in my project It is:

QDir::homePath()

QDir::homePath()

To copy to clipboard, switch view to plain text mode 

In Win XP it is C:/Documents and Settings/%USERNAME%/
In win 7 C:/Users/<username>/
