Often happens to us, we work a document, then somebody upset it without marking revision of changes and sooner or later occupy to make comparison of the two.
Despite seldom I write about themes of programs for mere mortals, I take this opportunity because this function includes Microsoft Word, and does it a thousand wonders. From the outset it is suggested that both documents be passed to the .docx version in case they were not, to facilitate the comparison under XML structures that support the new format.
To do the process you have to go to the option Compare, In the tab Check. A panel appears in which you choose which is the original document and which is the final document and on behalf of who we hope will be labeled the found changes.
There is also an option to extend the panel in the configuration of what we hope to compare; You can choose if you want to check changes of format, movement, change of capitals, changes in tables, in order ...
You can also choose whether to mark the changes at the character level or mark the whole word and then, if we wait for the changes marked in one of the two documents or a new one.
The result shows simultaneously, according to the choice marked in the upper circle, on the left the result of the revision and on the right the two documents compared. See that they are marked in different colors what has been modified, removed or added; The final result can be saved as a new document with revisions that are displayed when the mouse is moved or as calls in the right panel of the document.
It seems to me of the great qualities of Word that we rarely take advantage of.
