Documentor's duplicate-cleanup workspace now recognizes that some copies are kept on purpose – a canonical version, a disclosure copy, a delivered set – and lets you settle those once and apply the decision across a whole project, without ever being forced down to a single file.

• New multi-keep patterns let you keep copies in several legitimate folders at once and drop only the stray duplicates elsewhere, applied across every matching set in one step – so a recurring 'keep these, drop the rest' decision is made once rather than file by file.
• A 'mark kept' control resolves a set you intend to keep as-is, so it counts as done and stops reappearing on future scans – while a newly added copy still brings the set back for review.
• Patterns now respect group size: a decision made on a two-copy group applies only to other two-copy groups, so a simple case never bleeds into a more complex one.
• The entire cleanup session is now safely abandonable – review your exclusions and keep-marks, then Save or Discard – with 'important to review' stars kept independent so they are never lost.
