ChangeTypeCreator CMM, v1.03, Freeware

ChangeTypeCreator CMM plugin is a complementatary of the CTC application. It does not allow you to do as much as CTC, but it is more convenet for general graphics and selection of other commmon files.

It can Add or Remove Winodws three change suffix on one file or multiply files. For the Macintosh Picture file call "picture1" the plugin will give you the option on the left. For the file "myImage.gif", the option on the right is given.

Possible errors:

- Duplicate file name and file is left unchanged or file names that are too long.

Example of using ChangeTypeCreator CMM Plugin to correct the file type and creator of an Acrobat Reader file downloading from the web. Since web site was not configured with the PDF mime type and the user save the file to disk (as you may with to view the file off-line later) the file would be more useful, if you could double click on the icon and have it open Acrobat Reader directly. To correct this with CTC Plugin install do the following:

  1. Select the file to correct
  2. Control-Click on one of the files.
  3. Select Set File Type and Creator menu item.
The second step above results in the Contextual Menu being shown below.
CMM screen dump
and with the corrected file information the ICON is correct and the file is double clickable

Any valid Image file (and a few other known file types) wth the wrong file type, the CM plugin will attempt to determine the File Format and give you an option to correct the file type.

The file types: 'TEXT', '????', 'BINA' are common incorrect file type for file transfered from other types of computers.

QT Graphics Importer XTND translator, and other applications require correct Macintosh file types to be set to be able to open and use the images.

See Change Type and Creator (CTC) applicaton documentation for list of file types that the internet header check knows about.
