:DISK:FILE:SIZE?

:DISK File Transfer Commands

Query Syntax

:DISK:FILE:SIZE? "filename"

Description

Returns the size of a file in bytes. To determine if a file exists, use the :DISK:FILE:EXISts? query. If file does not exists, 0 is returned. To return a time stamp for the file, use the :DISK:FILE:TIMestamp? query.

SCPI commands that perform general file I/O operations are limited to Standard Infiniium File Types and Standard Infiniium Folders.

Example

This Python script (with PyVISA) tests if a specific screen image file exists and returns its size in bytes.
