Installing Drag & Drop Translators
Once you have copied the drag & drop translators applications onto you hard drive, they are installed. If the finder does not allow you to drag documents to them, you may need to rebuild the desktop file or set the correct file type of the file (see below).
To rebuild the desktop file, restart your computer and hold down the command and the option key on startup. The finder will ask you if you would like to rebuild the desktop file.
Application requirements for Drag & Drop support:
Requires system 7 or later.
Note: AppleScript is required for AppleScript scripting support.
The CTC has been tested for Year 2000.
Change Type and Creator (CTC) is a freeware application that optionally uses
Internet Config (IC) to select the suggested Macintosh File Type & Creator by
suffix matching. The creator allows you to double click on the file in the finder
and launch the application who created it. The file type is used by applications
to filter out file they can not read.
Use the preference dialog box to set options. Full balloon help is available.
Use Internet Config, Internal header check and batch mode are options.
End of Line (EOL) conversion only work on file of type TEXT. The problem that
*could* occur is that you mistakenly select a non-TEXT file along with other TEXT
files and convert them all to type TEXT *and* convert the EOL characters to the
selection of your choice. That's the danger. Don't do it.
Note that EOLs on DOS files are <CR><LF> (VAX also uses this EOL format) on
Macintosh files are <CR> on UNIX files are <LF>. If you are, this little hack
will surely help. Very useful for moving TEXT files between DOS, Mac, and UNIX
machines by diskNet (copy file onto disk, remove disk, sneaker it to other machine, ...).
WARNING: The EOL convert code reads the entire file into memory at one time, then
does the conversion as the file is re-written. If you don't know what you
are doing, things *could* get pretty fouled up with EOL conversion. They might
not. UNDO is not supported.
"Cross-platform compatible" file names and extensions
How CTC works:
For each file dropped on CTC or selected CTC does the following:
- If installed and enable CTC uses IC to return the file type using IC's suffix
- if enable, the file type is confirmed and/or updated if needed using
internal header check. This check read a few selected bytes from the file and
attempts to guess the correct file type from the content. Once the file type
is selected CTC will suggest a creator for that file type, if IC is not
installed. Creator return by IC is not change.
File type CTC internet header check knows about:
|Format of the file (creator)
|| File Type|
|| 'PDF '|
|Audio Interchange files
|Common Ground™ files (CGVM)
|IBMpc '.EXE' files
|JPEG (JIFF) files
|Next/Sun ULaw sound file ||ULAW|
|PICT files (ttxt-TeachText)
|PhotoShop V2.5 files (8BIM)
|Portable Network Graphics (PNG)
|Rich Text Format (RTF)
||RTF or TEXT (set in Preferences).
|Windows .WAV sound file
Internal list of default creator based on file types
(Use the Internet Control panel (or Internet Config) to override this list):
|TIFF, JPEG, BMPp, GIFf
|PNGf & PiNG
||HTML Viewer V1.2|
- if not batch mode, prompts with suggested file type and creator
(listing old file type and creator and if exit on local hard drive application
name of suggested creator)
- if the file type is 'TEXT' check, and if EOL conversion is selected. if so read
file into memory and convert and overwrite old file.
