No, LISTCAT will not tell you which files have data.

You need to test each file individually to see if the file is populated.

individually yes i know that!

but like we use 3.4 option and when we give the base name to the right it will show tracks% .

if tracks% is 0 then dataset is empty
if tracks% is100 then it has some data...

so i want this information by a utility (not individual checking).

thanks,[/quote]

Arvind, what you're looking at through ISPF 3.4 option is individual dataset usage data; you can replicate this in batch via the DCOLLECT command in IDCAMS.

From the manual:
Quote:
NODATAINFO
says that no data set information records are generated or written to the output data set. Use this parameter if you want only volume information generated for the given volumes or storage groups.

Abbreviation: NOD
Try changing this to NOVOLUMEINFO since you are specifically wanting data set information.

You don't; you have to look in the output file for the GDG files one by one to get the space usage. DCOLLECT works on volumes or storage groups but then you have to do some filtering based on what you're looking for.
