Ini Files Manager

Ini Files Manager is a straightforward software application which addresses advanced users who want to edit INI, INF and CFG files.
These files store a program's settings, thus Ini Files Manager lets you customize the respective app's behavior according to your preferences. You can use it to simplify the installation procedure of multiple utilities, for instance.
Since this is a pretty powerful tool, inexperienced users are not advised to work with Ini Files Manager, as they may end up causing serious problems to the operating system and stop it from running properly.
The interface of the application resembles the one of a common word processing tool, so you shouldn't have any navigation issues. It doesn't put unnecessary accents to the GUI's appearance, thus supplying the user with a simplistic and effective workspace for modifying INI, INF and CFG items.
Files can be loaded using only the file browser, since "drag and drop" is unsupported. You can edit data as you normally would in a word processor, and save the changes to a new file once you're done.
Aside from this simple task, you can add fields with roots, values and comments from the Modify menu, as well as use a search function when having large amounts of data at hand. Plus, you can insert comments signs and customize the font, as well as create a new file instead of editing an existing one.
Ini Files Manager is very light on the system resources, has a good response time and works smoothly, without causing the OS to hang, crash or pop up error dialogs. We haven't come across any issues in our tests, since the tool did not freeze, crash or show error notifications.
On the downside, the utility has not been updated for a very long time. But, all in all, Ini Files Manager comes packed with the necessary and suffice options for creating and editing INI, INF and CFG files.
