Release all anchored objects at once

Dear All, I want to release an all anchored objects from my file. All anchors are created inside the table. I am using InDesign CS4.

I have a file for 4 pages which is containing more than 150 images to be released from anchored. That images should be placed in the same place. Only need to release. I want to do this for more than 100 files (400 pgs. it may increase in future). I tried this in Search/replace option using Object, but only i can able to find using custom option in the anchor options panel, not able to relase using search and replace.

Please help me ASAP.

Thanks in Advance, Thiru
