What Is the File Extension Tdl?
A file extension is the series of characters that appear after the period in a filename, and are selected by the programmers who create a particular piece of software or programming language. Because of this, it is possible for files to share a common file extension, but be completely unrelated, which is the case with Tdl files.
-
Identification
-
Depending on the program that created it, a file with a Tdl file extension is either a MathType translator definition language or a Tab delineated format file.
Sources
-
MathType translator definition languages are used by the Design Science MathType program, while Tab delineated file formats are used by a variety of spreadsheet programs such as Apple Numbers, Microsoft Excel and IBM Lotus 1-2-3.
-
Location
-
Both types of Tdl files are most likely to be found in the corresponding program file of the software that uses or created the file. For example, a Tdl file used for Microsoft Exel would likely be located in an Excel program folder.
Function
-
A MathType translator definition language is used to convert letters and other types characters into mathematical symbols within Design Science MathType. A Tab delineated file format allows you to create spreadsheets where items in equations are separated by pressing the tab key rather than using commas.
Considerations
-
MathType translator definition languages require Design Science MathType to function properly, while Tab delineated file formats need a spreadsheet program. If you experience an error message when trying to access a Tdl file, you may not have the appropriate program properly installed.
