I have been meaning for a long time to set some configuration parameters for specific file types including which applications open them by default. I deal with a lot of different file types and I am typically having to scroll through a long list of Mac applications to select the one that I want to open the file. Since its not easy to do this in one spot on Mac OSX Mountain Lion without adding a third party application I started looking around to see what was available and ended up with Default Apps by Rubicode. Below I describe installing Default Apps and how it works.

Earlier this I had an interesting problem where Internet Explorer would not launch all the way on a friends computer.

Below I briefly discuss modifying this setting on a Linux server using ISPConfig.

The easiest way to resolve this issue on a per user basis with an ISPConfig Linux server is to disable MailScanner for that user. MailScanner does provide numerous other security checks though so it is not recommended to disable it but if you must disable the file ending modification then modify the below files.

By default in Windows Vista all system files and folders are hidden as in previous versions of Windows. The difference is the typical menu is not at the top of Windows Explorer so how you might be used to turning on hidden files and folders might seem harder than it was before. Actually its exactly the same and if you follow the instructions below you will see all files and folders in no time.

  1. Open My Computer: Click the Windows icon in the lower left hand corner of Vista, scroll up to the right, and click Computer.
