Please do a DSPFD and look at this section...

Member size SIZE
Initial number of records . . . . . . . . : 10000
Increment number of records . . . . . . . : 1000
Maximum number of increments . . . . . . : 3
Record capacity . . . . . . . . . . . . . . : 13000
Allocate storage . . . . . . . . . . . . . : ALLOCATE *NO
Contiguous storage . . . . . . . . . . . . : CONTIG *NO

Does this file was ALLOCATE *YES. If it does you told the system to create the file and to preallocate the space needed to hold the number of records under Record capacity. Even with 0 records the file will be the size as if it contained all the records. Change that do a *NO

Subject: PF data space management

I have a PF with zero records and a size of 26,353,664; WOW zero records
and a file size of 26MB.

The physical file description attributes the file size to the "Data
