I am currently running processing on two feature classes (points, number of points are 5000+ and 8000+ respectively) in ArcGIS 10.2 on personal geodatabase using iteration and selection by attributes/location.
The size of PGDB intially is only about 2MB however after the processing finishes it increases upto 400MB. My outputs of the processing are saved in a separate file GDB.
Can anyone explain to me why the size of original PGDB increases. Is this because the SQL queries are also saved in that PGDB.
How can I delete them? All i need is the original PGDB (with the orginal size) and the outputs stored in a separate GDB.
