MMEMory:CATalog[:ALL]? [< folder >[< filespec >]]

Parameter
Any ; defaults to folder selected
valid folder name
by
MMEMory:CDIRectory
List all files in the folder MyData on the front panel USB storage device:
MMEM:CAT? "USB:\MyData"
List all state files in the root directory of internal memory:
MMEM:CAT? "INT:\*.sta"
If < filespec > is omitted or is *.*, the command or query acts on all files. You can also use the * as a gen-
l
eric wildcard: *.sta, abc*.*, and so on.
The catalog takes the following form:
l
< mem_used >,< mem_free >{,"< file listing >"}
The instrument returns two numbers and a string for each file in the folder. The first number is the num-
ber of bytes used on the drive. The second indicates the number of bytes available. Each < file listing >
is in the format "< file_name >,< file_type >,< file_size >" (including the quotation marks), where < file_
name > is the name of the file including file extension, if any; < file_type > is either STAT for STATe (.sta)
files, ASC for DATA (.csv) files, PREF for PREFerence (.prf) files, FOLD for folders, or null for all other file
extensions; < file_size > is the file size in bytes.
If no files exist, only < mem_used >,< mem_free > is returned.
l
Because the instrument uses a small amount of space in the flash file system for internal use, the
l
< mem_used > value is never zero.
