Open the result of the alignment that SDL Studio performs automatically in the Alignment view to correct any misalignments before importing the alignment results into your specified translation memory (TM).
When you open an alignment result file in the Alignment view, Studio displays the aligned source and target documents on two side-by-side columns. The two documents are segmented according to the segmentation rules that you specified for the selected TM before starting the alignment.
When you Align a Single File Pair, Studio automatically opens the alignment result file for review in the Alignment view. To save the *.sdlalign file on your computer for later review select Home tab > Save > Save As.
When you Align Multiple Files, Studio saves the alignment result file for each pair of documents if you keep the default Save alignment result files for later review option enabled on the first page of the Align Documents wizard. When the alignment is complete, Studio prompts you to open the folder with alignment result files. Select and double-click on the *.sdlalign result files to open them individually in the Alignment view.
If you have saved the alignment result file for later review, you can manually open the *.sdlalign file in the Alignment view.
To open an existing *.sdlalign file:
