- File
Type: File Specifies the file to create.
- Name

You can omit the full path if the file is located in the current directory.
You can enter only the subdirectory name if the file is located in a subdirectory of the current directory.
- TextEncoding
Value: MsDos, UTF8, UTF16, or Windows Optionally, you can specify the encoding on the file. By specifying the text encoding, you ensure that all the language-specific characters are represented correctly in Microsoft Dynamics NAV when you read data and write data. For more information, see Text Encoding.
Property Value/Return Value
Type: Boolean
Specifies whether the file was created.
true if the file was created; otherwise, false.
Remarks
If the TEXTMODE Function (File) returns true and you read or write to the file, text is put in the buffer.
If the TEXTMODE Function (File) function returns false, binary information is put in the buffer.
If you call CREATE on a File variable that refers to an open file, the function does not automatically close the existing file and create the new file. You must explicitly call the CLOSE Function (File) to close the existing file. Otherwise, a run-time error occurs.
Example
The following example creates a file that is named TestFile.txt in the path C:\TestFolder\. The TestFile variable stores the file and path that is created. If the file is created, a message that states that the file is created is displayed. Otherwise, an error message is displayed. This example requires that you create the following variable in the C/AL Globals window.

IF TestFile.CREATE('C:\TestFolder\TestFile.txt') THEN BEGIN
MESSAGE('%1 is created', TestFile.NAME)
