Mac OSX – Make Specific App Default File Opener

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.

How To Convert .WRF Files To .WMV, AVI, MP4, XVID, or MPEG

Someone sent me a WebEx webcast they wanted me to view this afternoon. The file had a .WRF file ending which stands for WebEx Recording Format which is one of the two file formats that WebEx webcasts are saved as. The other format that WebEx files are saved as is the ARF or WebEx Advanced Recording Format. Typically you could simply download the WebEx Player available by clicking here however you may want to convert this video, which requires the WebEx Recording Editor, to provide to others in a format they can view without having to install an application. It took me awhile to figure out how to convert this file properly since I only seemed to be able to find the older WebEx Editor versions. I finally signed up for a trial account and was able to download version 3 of the WebEx Recording Editor which allowed me to convert to WMV format and from that I was able to convert to any other video format including AVI, MP4, XVID, and MPEG. Follow the directions below to first convert the .WRF to .WMV and then the second set of directions if you want to convert to another video format.

Clean Macintosh iTunes Library By Batch Removing Dead Tracks

A friend asked me to help him clean up his iTunes library on his iMac the other night so I asked him to bring it by. When he did I realized what had happened which is he had moved the location of his iTunes folder from his computer to an external drive. After moving the folder he imported all of his music again which caused iTunes to think his 8,000 MP3’s had become 16,000 MP3’s. Half of the tracks had red exclamation points by them because iTunes had information about them but could no longer locate the file since he had moved all of the music to a new folder in a different location. I found an easy solution to resolve this problem on a Mac which I describe in detail below.

Roxio 2010: The File You Are Trying To Use Cannot Be Edited, And Has Not Been Added

When using Roxio Creator Premier 2010 to encode a video to DVD format and burn to disc I received an error. I have been burning AVI, MPEG, MP4, Quicktime, and other video formats using this version of Roxio Creator 2010 for some time so I was surprised to receive an error. Initially I thought that the error was caused by file permissions on the file because a friend had provided it to burn and this was the only initial difference that I could find with the video versus other videos that I had burned. Below I describe how to troubleshoot this error and what I eventually did to resolve and move past this error. In the end I was able to burn this video using Roxio Creator 2010.
