File Associations in Windows® XP®
Are you interested in knowing the role of file associations in Windows® XP?
File associations in Windows XP is used to associate a file with an application which can run that file. In order to open a particular file, the application with which that file type can be run needs to be installed on the system. A single file association might have several associations for performing various actions such as open, edit, print etc that are also known as verbs. In Windows XP, the file associations are stored in registry as sets of verbs for each file extension. You could change file-type associations in Windows XP to make one application as default for all files of the same type. File association in Windows can be changed in order to perform the action by using a different application. The file association can be changed in Windows XP by changing the file type under registered file types list in ‘Folder Options’. Also the file association can be changed to a different program after choosing a program in the ‘Open Option’ of a particular file. The option “Always use the selected program to open this kind of file” needs to be checked so that similar files can be opened with the newly selected program.
