Tablespace - regain unused space

oracle 10.2.0.4

OS: Linux 6

I have various tablespaces that around 40% free and like to regain these space.

For example: TS_Data01, Total size 1 TB with 50 files. many of these files are half empty. when I try to resize these files, Oracle will not let me do this operation.

Error: ORA-03297: file contains used data beyond requested RESIZE value

What are my options besides from rebuilding table and indexes in the same tablespace?

How can I coalesce these space and regain?

Thanks.

Howdy, Stranger!
