:DISK:TFILe?
Deprecated command. For FlexDCA revision A.05.30 and above, use the :DISK:FILE:ASCii:READ
command instead.
Query Syntax
:DISK:TFILe? "filename"
Description
Returns the requested text file. The file must be smaller than 256,000 characters. If the file does not contain text, the return string will be terminated at the first zero (0) values byte in the file. To return a binary file, use the :DISK:BFILe
command.
Security Restrictions
Starting with FlexDCA revision A.07.90, file I/O security was increased when reading or writing files using the :DISK:FILE
, :DISK:BFILe?
, and :DISK:TFILe?
commands. FlexDCA no longer permits arbitrary file types, arbitrary folder access, or reading and writing to network share drives. The following "Valid File Types" and "Standard FlexDCA Directories" tables identify the type of files and location that you can read using the :DISK:BFILe?
and :DISK:TFILe?
commands.
Sending a :DISK:TFILe
command that specifies a network share drive, a restricted directory, or with a restricted file name results in –258, Media protected.
error code.
You can use the :DISK:TFILe?
query for the files marked in the following table as format Text.
