Where Tracked Changes can Appear
Tracked changes can appear in two locations in your document:
Source Segment Tracked Changes
- Source segments
- Target segments
Tracked changes in the original source document are displayed in the source segments. However, these changes cannot be amended and new changes cannot be made in Studio.
Studio only supports working with tracked changes in the source for Microsoft Word 2007-2013 documents (.docx). To view source tracked changes in Studio, change the Track changes extraction mode setting to Display pending changes in the file type settings for Word 2007-2013 Settings.
Target Segment Tracked Changes
You can track the changes you make in translations in target segments. The translator can then choose to accept or reject tracked changes suggested by a reviewer in target segments You can do this for one suggested change at a time or for an entire document.
Previewing Documents with Tracked Changes
When previewing documents that contain tracked changes, you can only see the tracked changes in the preview for Microsoft Word 2007-2013 documents (*.docx). For all other file types, tracked changes will appear as if they are accepted in the preview.
The takeaways for this are these:
- Track changes is not supported in target RTF files
- You need to remove track changes for all Word formats apart from DOCX where you can open files with tracked changes and even display the changes
