:DISK:BFILe
Deprecated command. For FlexDCA revision A.05.30 and above, use the :DISK:FILE:READ command instead.
Command Syntax
:DISK:BFILe "filename", <binary_data>
Query Syntax
:DISK:BFILe? "filename"
Description
Sends or returns the requested binary file in the definite-length block data format, which allows any type of device-dependent data to be transmitted over the system interface as a series of 8-bit binary data bytes. This is particularly useful for sending large quantities of data or 8-bit extended ASCII codes. The syntax is a pound sign (#) followed by a non-zero digit representing the number of following digits (decimal integer) that states the number of 8-bit data bytes being sent. This is followed by the actual data. For example, for transmitting 3000 bytes of data, the syntax would be: #43000<3000 bytes of data>. The leftmost character "4" represents the number of digits in the number of bytes, and "3000" represents the number of bytes to be transmitted. Byte order can affect the ability of your programs to correctly interpret block data. The byte order, or endianness, of returned block data is LSB (Least Significant Byte) first and is identical for both Waveform and Measure subsystem data.
To return a text file, use the :DISK:TFILe 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:BFILe? query for the files marked in the following table as format Text.

When using the :DISK:FILE commands, files can only be read from or written to the directories that are listed in the following two tables. This includes any sub-directories that are in the listed directories. The first table lists FlexDCA's standard directories. The second table lists folders that are not typically used but are available for you to read and write to.
