Managing folders and files
Folders, data files, and state files created in internal flash memory and on a USB
storage device can be managed (i.e. deleted, copied, moved, cataloged) from the
front panel or using additional commands within the MMEMory and MEMory
subsystems.
Deleting folders
Folders are deleted (removed) using the command:
MMEMory:RDIRectory “<folder>”
When deleting a folder from an I/O interface, the folder must be empty
(containing no sub-folders or files). The folder designated as the current folder
(MMEMory:CDIRectory) cannot be deleted. From the front panel, un-empty
folders can be deleted (as prompted) as can the (SCPI designated) current folder.
Deleting a folder example
The following example deletes a sub-folder (empty) followed by its root folder.
//create USB folder ‘dut_2’ and sub-folder ‘data2’
MMEM:MDIR “USB:\dut_2”
MMEM:MDIR “USB:\dut_2\data2”
//remove sub-folder ‘data2’ then remove folder ‘dut_2’
MMEM:RDIR “USB:\dut2\data2”
MMEM:RDIR “USB:\dut_2”
Deleting files
Data and state files located on the instrument’s internal flash drive or on a USB
memory device (Figure 7-2) are deleted using the command:
MMEMory:DELete <“file”>
The file format is “[drive:path]<file_name>”. drive is either INT (internal flash
memory) or USB (external memory device). If the file deleted is not in the specified
current directory, path is an absolute folder path beginning with ‘\’ and starting at
the root folder. The file name must include the file extension. For example:
\\ delete data file data1.csv in USB folder dut_1
MMEM:DEL “USB:\dut_1\data1.csv”
