Q: Why do I need File Associate?
A: File Associate comes handy when you want to use another application to open a certain type of data file, instead of the default application viewer assigned by the system.
The accompanied Generic viewer application can be used to view flash, ZIP, text and binary files.
Q: Which phones is File Associate compatible with?
A: File Associate can be installed and executed on all smartphones running on Symbian 9.x with UIQ 3.x.
The ability of changing file type associations is available on SonyEricsson phones.
Q: What is a file type?
A: The file type characterizes the actual contents of a file. The two main types are executable and data. There are several types and subtypes of data files, like sound (audio), image (visual), document (text and other), and many more.
Q: Is the file extension identical with the file type?
A: No. The extension is the terminal part of the file name, separated by a dot character. The file extension is normally used as a hint for the file type. The true file type, however, refers to the contents of the file, independent of its name. You can rename a text file to have the .jpg extension, which however will not change its contents (and therefore, type) to be an image.
Q: What is a viewer?
A: A viewer is an application that can recognize and process a data file whose name is passed to it from another application. When you open a file from a file manager, the operating system passes the file's name to the application currently associated with the type of that file. A true viewer will display, play, or otherwise process the passed file. An application that can display (for example) images is still not a viewer, unless it is programmed to accept and process a passed file name.
Q: Where can I find the file type I'm interested in?
A: If you are looking for a specific data type, switch to the Advanced view from the menu. In the Settings dialog use the Include options to choose what types you want to list. Do not select the Common types if you want a detailed listing.
Q: Can I see what exact application is associated with a file type?
A: Yes, just select the desired type on the list, and issue the View command to switch to Association view and see the details.
Q: Can I assign any application to any file type?
A: Yes, you can set any application present on your phone to any file type, using File Associate.
This facility, however, can not guarantee successful file viewing in all cases (see the next FAQ item).
Q: Will all arbitrary associations work?
A: Definitely no. It is very important to realize that the association itself can not provide features that an application might not have.
If you associate a file type with an application which is unable to display that kind of file then the result will not be what you want.
As an extreme example, associating sound files with the Contacts application would not provide Contacts with the ability to play audio files.
For success, you need to have and associate an application which has been programmed for viewing the file type in question.
Q: Which file type should I change for MP3 files?
A: The following file types belong to some common sound file extensions:
- .mp3: audio/mpeg
- .mid: audio/midi
- .wav: audio/wav
Note that not all popular music players can act as true viewers for audio files.
Q: Why my favorite music player does not play files?
A: Most probably that application was not programmed to act as a true viewer.
True viewers are able to accept, recognize, and process document files passed to them by issuing the Open command from a file manager.
Several popular applications are unable to act as true viewers.
Examples of such applications are LCG Jukebox, PowerMP3, X-plore, Opera Mini, and FoxIt.
Examples of true viewers are Documents To Go, MobiPocket Reader, and Projekt.
Q: I assigned the flash type to Web but I get a "Not supported" message, why?
A: The built-in Web application (Opera) is not a true viewer, so it can not display flash files by association. Instead you need to associate flash files with Generic viewer, which will pass the file to Web for displaying.
Q: Why my changed associations do not work within X-plore?
A: By default X-plore uses its own file viewing mechanism. To respect the file associations maintained by the operating system (and manipulated by File Associate), issue the Open by system command of X-plore.
Q: What to do if I messed up associations?
A: You can use the Restore command to revert the association for the selected type back to the original viewer, as determined by recognizers. If several associations have been changed unsuitably, then the Restore all command can be used to revert all displayed associations.
Q: After installing File Associate I still can not view ZIP files, why?
A: File Associate declares some new data types for ZIP, flash and binary files. These system-level changes only take effect after the phone is restarted. Therefore, File Associate prompts for restart when it runs for the first time after a fresh install.
Q: How to view flash files?
A: Make sure that the application/x-shockwave-flash type is associated with Generic viewer. Also make sure that the Opera Flash Plug-in is installed on the phone. If both these conditions are met then upon clicking on a flash (.swf) file the built-in Web application will play the file.
Q: Can I view RAR files?
A: Generic viewer provides no specific support for RAR files, therefore this type of file will be displayed as a binary file.
Q: What to do if I want to view local HTML files with the Web application?
A: To achieve that you need to associate the text/html type with Generic viewer, and enable the HTML option in the Viewer settings.
