Get ctp File Recognized in Dreamweaver

 There are ultimately 3 files that you need to edit. The first two are located in the folder that you installed Dreamweaver, in my case this is “C:\Program Files\Adobe\Adobe Dreamweaver CS3\configuration” although I’m using the latest version of Dreamweaver previous versions also have a “configuration” folder so go there.
Open up “Extensions.txt” and on the first line at the very end add THTML and CTP separated by commas, so the line should read:

1. ,MASTER,THTML,CTP:All Documents  

Similarly add these two extensions to the “:PHP Files” line.

1. PHP,PHP3,PHP4,PHP5,TPL,THTML,CTP:PHP Files  

Next open the “DocumentTypes” folder and edit the “MMDocumentTypes.xml” file, just open it up using notepad or wordpad. Search for the line which has an id “PHP_MySQL” and add the THTML/CTP file extensions to both the “winfileextension” and “macfileextension” so the line should read:

1. winfileextension="php,php3,php4,php5,thtml,ctp"   
2. macfileextension="php,php3,php4,php5,thtml,ctp"  

The final file is another version of the “Extensions.txt” which is located in your “Documents and Settings” Folder in my case this is “C:\Documents and Settings\James\Application Data\Adobe\Dreamweaver 9\Configuration” just add the very same things you inserted earlier.

Final Step

Restart Dreamweaver and you should now be able to open up and edit .THTML and .CTP files with everything nicely colour coded. A short post but a needed one for those who use Dreamweaver.
