Formats and Data Flow 7
Specifying a Default Folder
Designating a folder as the default (current) folder eliminates the need to
specify an absolute path each time a sub-folder or file is created or referenced.
The command:
MMEMory:CDIRectory “<folder>”
MMEMory:CDIRectory? (query form)
selects folder as the current folder used by subsequent MMEMory subsystem
commands. folder is of the form drive:path (see MMEMory:DIRectory
for drive:path details).
For example, an alternate way to create folders dut_1 and data1 is:
//create folder ‘dut_1’ and select it as the current folder
//create sub-folder ‘data1’
MMEM:MDIR “INT:\dut_1”
MMEM:CDIR “INT:\dut_1”
MMEM:MDIR “data1”
When specifying a folder name the current folder is referenced. If a current
folder (MMEM:CDIR) has not been specified and a drive name (INT or USB) is
not included, the default drive ‘INT:’ is referenced. For example:
MMEM:MDIR “dut_2”
creates the folder ‘dut_2’ on the root drive INT.
Following a reset (*RST) or instrument preset (SYSTem:PRESet), the counter
resets the current folder to the root directory on the internal flash file system
("INT:\") .
