![]() ![]() The file types I typically deal with are going to be video and image media (imagine a post production house) so I'm compareing file sizes, date created, file name, etc. What if it was setup with Three columns, the far Left column could move "right" to Center, The Center Column could move Right or Left, and the far Right column could move Left, then you could just re-arrange which column was "center" through a "swap sides" type button(s) Compare price, features, and reviews of the software side-by-side to make the best choice for your business. I could imagine trying to develop a "Move Left" or "Move Right" control structure could be a challenge. Right now when I compare files between Dev and Test, and then Test and Production, I have to do 2 seperate sweeps, if I had a "3 way" folder compare, basically 3 compare windows, 1 for each tier, this would allow me to compare contents, and then move contents as appropriate between tiers. We match the folder structure across all three storage tiers for simplified navigation. we process and test in Dev, store our test files in another teir (test), and publish our live files into Production. Due to the nature of our storage SAN (muliple petabytes) we have files split across 3 seperate physical disk systems. We have 3 seperate processing folders, for the sake of this discussion I'll call them Dev, Test, and Production. ![]() The user needs the ability to freely edit all parts of the compare without analyzing differences and trying to merge them. In such a scenario, a three-way merge is useless (or would be cumbersome at best). By nature, the three folders may need to remain unique with changes made to each folder that are specific to the system they are being applied to. At some future date, the changes implemented in both branches of the source code may need to be merged back into one common set of source files.Ī three-way folder compare would be useful when you simply want to see how files differ between computers 1 and 2 to get an idea of how to modify the files for computer 3. A 3-way file compare would allow the user to freely edit all three files and copy data back and forth between all three of them.Ī three-way folder merge would be similar in that it would identify changes in two sets of files and folders branched from a common ancestor, attempt to apply the combined set of changes from both sets of files into a new set of files in the output location (whether that location be a new folder, or one side of the folder compare into which changes from the other side will be merged in.)Ī three-way folder merge would be useful in a version control scenario where the code base for a product is branched, and a separate set of enhancements (or defect fixes) are developed in each branch of the source code. There is no output file in a 3-way file compare. ![]() The difference is that a 3-way file merge analyzes the input files to create an output file with the combined differences. BC3 does not currently support a 3-way file compare. It integrates with many source control and works on Windows/Linux. ![]() Its somewhat less visual than P4V but way more than WinDiff. I usually turn off all the options under "Unimportant Text" such as leading whitespace, case, line endings, etcetera.Just to be sure that I understand, what exactly do you mean by 3-way folder merge?A 3-way merge detects changes that have occurred in two sets of objects branched from some common ancestor, and merges them together to create a third set of objects that contain both sets of changes (alternately, the set of changes from one side is merged into the other side so that the other side contains all of the changes.)īC3 currently supports a 3-way file merge. Beyond Compare 3, my favorite, has a merge functionality in the Pro edition.The good thing with its merge is that it let you see all 4 views: base, left, right, and merged result. When viewing a file comparison, use the referee icon (or the Tools | Edit Current Rules menu) to tweak the file comparison rules.Use the little scales icon (or the Session | Comparison Control menu) to switch the comparison type to Size and CRC. The default comparison is file size plus date and time, which is super speedy but not always accurate.Make use of the ultra-handy right-click explorer file and folder context menus to compare stuff.Here are a few beginner tips when using Beyond Compare: If you haven't tried it yet, what are you waiting for? Are you writing your own diff program in c#? Give it a 30-day trial spin, and check out the viewer plugins, too. Diff Doc in 2023 by cost, reviews, features, integrations, deployment, target market, support options, trial offers, training options, years in business, region, and more using the chart below. I've mentioned Beyond Compare before, but even a year later, few developers seem to know about it. This amazing little folder and file differencing tool has earned its spot in my core toolset a dozen times over. It's a shame that Beyond Compare isn't listed in more "favorite tool" lists. ![]()
