This results in file size and binary differences even when the visible file has not changed. It also keeps track of the time the file was last accessed.
Microsoft Office includes version and timestamp information in all office file formats. Two Microsoft Office (Word, Excel, PowerPoint) files may look the same, but have different file sizes, or the timestamps may change after viewing the files even though they were not changed. Enable the Rules-based comparison option.
In the Folder Viewer, select Session | Comparison Control. To compare files in the Folder Viewer like in the File Viewer: Enable the Compare contents option and make sure Rules-based comparison is enabled. In the Folder Compare, select Session | Session Settings and pick the Comparison tab. To compare files in the Folder Compare like in the file viewers: You can use a Hex Compare session or the Text Compare's View | Hex Details to identify byte differences. When line endings are different, a binary comparison will show a mismatch even though the actual text is the same.įor instance, Windows puts CR and LF control characters at the end of each line, while Unix uses LF alone.įiles that have been copied or edited on different systems can end up with different line ending styles. If two text files look the same but show differences, it's likely there are differences in line endings. Unchanged files aren't mentioned, but counted for brevity (usually you'll have way more unchanged than changed files I imagine).Īlso works on linux, for you powershell users out there running it there :)įor those curious, the unchanged files were clrcompression.dll,logo.png, logo.png, logo.png, and logo.Files are the Same, but Beyond Compare Says They are Different Plain Text 
We can see exactly at which versions files were added and removed from the. $firstFolder = Get-ChildItem -Recurse $folder1 | Where-Object | DiffFolders | Out-GridView # Get all files under $folder1, filter out directories Here is the powershell code for that: $folder1 = "C:\Folder1" It looked like the script was hung to me.
Please note it also shows progress made since it was hard for me to see that given the huge folders with not very many differences. I have taken jscott's answer an expanded it to output the files that are present in one but not the other for those who are insterest in that type of functionality.
