The problem
A collaborator sends back an edited copy of your website. Some changes belong in your version, but an old phone number should stay out. Replacing the whole file would bring both kinds across.
The solution
Compare the two folders in Diff Anything, open the changed home page and copy only the edits you want. Save that file, then use Pro to copy a new page from the other folder. Everything stays on your Mac, with no AI involved.
01 / File and folder merging on Mac
The tutorial compares a bakery website with Anna’s edited copy. Subfolders are included. The differences list shows a changed home page and a page that exists only in Anna’s folder; identical files have their own filter.
Open the changed file to review both versions side by side. Changed lines and the exact words within them are marked.
02 / File and folder merging on Mac
The example keeps Anna’s typo correction and Saturday opening hours, but leaves out her old phone number. Select each wanted change and click Right to left to copy it into the original on the left. Left to right works in the opposite direction.
Copying a text change edits the open comparison. It does not write that edit to disk until you click Save and confirm overwriting the existing file.
03 / File and folder merging on Mac
Return to the folder results and use the row arrow to copy Anna’s new events page into your folder. Folder copying writes the file to the destination; it has its own Undo copy action.
Folder copying and synchronization require Pro. Applying selected changes between two text files and saving the edited text are available in Free within its limits.
04 / File and folder merging on Mac
Free allows 10 new comparison sessions per local day, text files up to 5 MiB per side and the first 100 folder results. Pro removes those preview and session limits, supports larger sources within technical safety limits and adds folder copying and synchronization.

WinMerge’s official downloads are Windows installers and binaries. Diff Anything is a separate app for Mac, not a version of WinMerge or an affiliated product.
Clear answers
Yes. Select a difference and use Right to left or Left to right. Review the edited text and save the file to write your changes to disk.
Folder copying and synchronization require Pro. Free can preview the first 100 folder results and open changed text files for comparison, editing and applying selected text changes within its file and daily limits.
Three short steps
Click Compare two folders and select your folder on the left and the returned copy on the right.
Open a changed text file, select an edit and use Right to left or Left to right. Save the file when you are ready.
With Pro, copy a new file with the arrow in its folder row. Use Undo copy if you need to reverse that copy.
