How to Delete Preferences
Preferences files are tiny. Well behaved applications use a few millionths of a dollar of disk space for preferences. Nobody needs to delete a preferences file to recover disk space.
Unless They Cause Problems
If an application crashes 3 times in a very short time Mac OS may ask if it should delete the preferences file.
You may do so, but you might need to reenter your license code afterwards if it is for an application you bought.
Delete it Manually
- Open your Home folder.
- Open the Library Folder inside.
- Open the Preferences folder inside.
- Find the preferences you wish to delete, and drag it to the trash or your desktop. Most are named like "com.company-name.application-name.plist" so you can see which application it belongs to.
