Writing/Replacing files

[vineet.jain]

My project's files are placed inside the /opt/projectname/bin/somefolder.Now how can i replace a file which is kept at the same path.

I am successfully reading the xml file from the above path, but now the requirement is such that i have to replace that file at run time with a new file of same name.

I tried with QFile methods, but unable to write a file at this location.Does it requires any credentials to be added in manifest file or else?

Hi,
Your app should not write any file in /opt. You should read/write files only in the HOME (/home/user) directory.
The first time your app is launched it can copy the file from /opt to QDir::home() + "/.local/share/data/yourAppName".
Then you can write and read it.
Writing files which are installed by debian files is risky. The package manger can complain and fail uninstallation process.
