Ultimate power is multi-document processing where you only need to provide starting folder/drive/network location and ReplaceMagic will scan and
make changes in all found documents.
Additional benefit to all Web developers is that ReplaceMagic.Text can identify hyperlinks in processed documents.
Professional edition allows you to make scans and search&replace anywhere on your network where you have access from computer where ReplaceMagic is installed.
To use ReplaceMagic, create list of search/replace pairs and specify where in the document it should be found. Then you tell it which folders to process and it is it - it can not be more simple!
