Baloo File Indexer / File Extraction

How to fix Baloo File Index --> Disable it!

Problem

Many desktop indexers as they are implemented in KDE unfortunately are problematic. They are slow and resource hogs, taking up gigabytes of drive just to store indexes of files you won't use. Worse yet, they habitually lag my machine. The problem really arises when I'm copying multiple gigabytes of files over USB (but usually less than 30 files total). The Baloo file extraction process starts up and lags frequently.

Unfortunately there is not neat graphical way to disable the Baloo indexer. 

Quoting one of the Baloo authors:

There is no explicit “Enable/Disable” button any more. We would like to promote the use of searching and feel that Baloo should never get in the users way. However, we are smart about it and IF you add your HOME directory to the list of “excluded folders”, Baloo will switch itself off since it no longer has anything to index.

Solution

Here is how to disable Baloo from operating. Edit the file $HOME/.kde/share/config/baloofilerc. It is enough to edit it and change the option:

Indexing-Enabled=true 

to (or add if there is not such option)

Indexing-Enabled=false

to disable baloo.

I know it is way too easy but it did work for me and also for the guy who posted this simple solution on this page.
