But that might give a very inaccurate number because the number of objects can affect how much space that you can use. Objects are allocated in blocks, and blocks usually are not full. Some space in a block is often not used.

So a larger number of smaller objects might use a lot more space than a single large object with the same amount of data.

Or a database file might have records that require padding or alignment of fields. Inefficient record formats may result in a large amount of wasted space, especially if they hold a large number of records.

then
Total memory – Total free space = *****

By this way also can compute.

Call the Retrieve System Status (QWCRSSTS) API and request format SSTS0200. The % system ASP used is at offset 52.
