如果您组织文件，您可能有一个包含所有数据的文件夹和子文件夹网络。如果您发现自己的组织过度，您可能希望将两个文件夹合并为一个。
但是更改现有文件夹结构比听起来要棘手。没有文件夹合并按钮来合并多个文件夹——您需要手动进入每个目录，按Ctrl + A 选择所有文件，在目的地创建新文件夹，然后复制粘贴文件。
幸运的是，还有许多其他方法可以在Windows 10（或 Windows 11）中合并文件夹。从第三方应用程序到内置的Microsoft Windows方法，以下是其中最好的方法的概述。
在Windows 10/11同名(Same Name)文件夹
在我们进入第三方应用程序或Powershell脚本之前，让我们看看可用的默认选项。虽然Windows中没有“文件夹合并”选项，但有一种方法可以通过复制粘贴来合并文件夹。
当一个文件夹复制到另一个同名文件夹上时，Windows会自动合并其内容，提示您解决出现的任何文件冲突。这是如何做到的：
- 找到要合并的两个文件夹。如果它们的名称不相同，请重命名其中一个以匹配另一个。
- 现在只需复制第一个文件夹并将其粘贴到包含第二个文件夹的目录中。您可以使用右键单击方法或只需点击键盘快捷键（Ctrl + C用于复制，Ctrl + V用于粘贴）。
- 如果两个文件夹中的文件都不共享名称，则文件夹将被合并，无需任何额外步骤。如果发生冲突，Windows会询问您如何处理这些文件。您可以替换它们，跳过这些文件，或根据具体情况决定。
就是这样。您需要做的就是确保它们具有相同的文件夹名称，然后将一个复制到另一个上。Windows负责处理细节。
对于只想合并两个不同文件夹的内容而无需任何高级文件比较的临时用户来说，这是最好的方法。如果您希望在文件夹合并期间应用其他标准来解决文件冲突，则需要专用的第三方工具。
使用Powershell 脚本(Powershell Script)合并文件夹(Merge Folders)
虽然复制粘贴方法易于使用，但在处理多个文件夹时可能会有点耗时。系统(System) 管理员(Administrators)经常同时处理数十个系统，因此他们需要一种可扩展的方法来合并文件夹。
与大多数自动化任务一样，我们将使用Powershell来实现这一点。我们所需要的只是一个遍历父文件夹内容的脚本，比较每个文件名以查看是否匹配。您可以选择替换不同的文件或完全不覆盖它们。
$sourcePath = “C:Folder1”
$destinationPath = “C:Folder2”
$files = Get-ChildItem -Path $sourcePath -Recurse -Filter “*.*”
foreach($files 中的$file){
$sourcePathFile = $file.FullName
$destinationPathFile = $file.FullName.Replace($sourcePath, $destinationPath)
$exists = Test-Path$destinationPathFile
如果（！$存在）{
$dir = Split-Path -parent $destinationPathFile
if (!( Test-Path ($dir))) { New-Item -ItemType 目录-Path $dir }
Copy-Item -Path $sourcePathFile -Destination $destinationPathFile -Recurse -Force
}
别的{
$isFile = Test-Path -Path $destinationPathFile -PathType Leaf
如果（！$isFile）{
Copy-Item -Path $sourcePathFile -Destination $destinationPathFile -Recurse -Force
}
}
}
此脚本使用循环(loop)将源文件夹的内容递归复制到目标文件夹，在发生冲突时保持原始文件不变。您可以以不同的方式解决冲突（通过替换旧文件等），并使用源路径和目标路径的参数使其更加灵活。
轻松合并文件夹的第三方应用程序
有几个第三方应用程序可以使合并文件夹的过程更加容易。它们的复杂性从基本的GUI合并工具到支持版本控制的完整文件比较软件。
以下是Windows 10(Windows 10)和 11中用于合并文件夹的最佳第三方应用：
Windows本身无法在复制时比较相同文件的内容。它所能告诉您的只是它们的文件大小和日期，让您在遇到重复文件时手动确定要保留的文件。
WinMerge是一个开源程序，用于在Windows中比较文件和合并文件夹。它对编码人员和系统管理员来说很方便，因为它可以比较文本文件的内容并以可视格式呈现它们。
如果您只想要一个简单的基于 GUI 的文件夹合并工具，2XDSOFT 的文件夹合并(Folder Merger)是一个不错的选择。它允许您从具有许多自定义选项的直观界面合并文件夹和子文件夹。
您可以保留文件夹结构、使用文件名过滤器，甚至保留特定的子文件夹。最好的部分是该应用程序是便携式的——您可以将它放在笔式驱动器中随身携带，无需安装即可直接使用。
Araxis Merge (Free 30-day Trial; $129 Standard; $269 Professional)
Araxis Merge是一个强大的文件比较和合并应用程序，适用于Windows和 macOS。与WinMerge一样，它最适合那些使用许多文本文件的人，例如程序员或法律专业人士。
您可以认为它是一种更高级的WinMerge形式，具有高级文件比较功能，包括文本、图像和二进制文件。版本(Version)控制系统可以直接与Araxis Merge集成，以及通过命令行启用自动化的API 。
这个额外的功能不是免费的。Araxis Merge是一款高级工具，需要您购买许可证才能在 30 天试用期之后使用它。查看Araxis Merge网站了解完整定价(complete pricing)以及标准版和专业版的详细功能列表。(detailed list of features)
在Windows 10/11合并文件夹(Merge Folders)的最佳方法是什么？
如果您只是想将两个目录的内容合并到一个文件夹中，那么默认方法是最好的方法。只需(Just)打开文件资源管理器(File Explorer)，将其中一个文件夹重命名为相同名称，然后复制粘贴到另一个文件夹上，让Windows处理合并。
如果您必须定期合并多个文件夹或需要详细的文件比较算法，则只需要其他方法。如果您要合并文本文件，还有其他方法(other methods)。
Powershell脚本可能是最灵活的方法，因为 cmdlet 可用于根据任意数量的高级标准组合文件。唯一的问题是它需要对Powershell的语法有一点了解才能编写代码。但是，如果您想设置用于合并文件夹的自动化脚本，这是一种方式。
对于更用户友好的方法，您可以使用第三方应用程序。WinMerge和Araxis Merge等应用程序(Apps)允许您比较文件和合并文件夹，而无需精通编码。这使得它们对于那些批量处理文本文件的人来说是必不可少的程序。
How to Easily Merge Folders in Windows 11/10
If yоυ оrganize files, you probablу have a web of fоlderѕ аnd subfolderѕ holding all your data. If you ever find that you’ve over-organizеd a bit, you might want to mergе two folders into one.
But changing an existing folder structure is trickier than it sounds. There is no folder merge button to combine multiple folders– you need to manually go into every directory, press Ctrl + A to select all files, create new folders at the destination, and copy-paste the files.
Fortunately, there are many other ways to merge folders in Windows 10 (or Windows 11). From third-party apps to built-in Microsoft Windows methods, here is an overview of the best of these.
Merging Folders With the Same Name In Windows 10/11
Before we go into third-party apps or Powershell scripts, let’s look at the default options available. While there is no “folder merge” option in Windows, there is a method to merge folders by copy-pasting them.
When a folder is copied over another folder with the same name, Windows will automatically merge its contents, prompting you to resolve any file conflicts that arise. Here’s how to do it:
- Locate the two folders you wish to merge. If their names aren’t identical, rename one of them to match the other.
- Now just copy the first folder and paste it into the directory containing the second folder. You can use the right-click method or just tap the keyboard shortcuts (Ctrl + C for copy, Ctrl + V for paste).
- If none of the files in the two folders share names, the folders will be merged without any additional steps. If a conflict arises, Windows will ask you what to do with those files. You can replace them, skip those files, or decide on a case-by-case basis.
And that’s it. All you need to do is to ensure that they have the same folder name and then just copy one over the other. Windows takes care of the details.
This is the best method for casual users simply looking to merge the contents of two different folders without any advanced file comparison. If you are looking to apply additional criteria to resolve file conflicts during folder merge, you need a dedicated third-party tool.
Using a Powershell Script to Merge Folders
While the copy-paste method is easy to use, it can be a bit time-consuming when working with many folders. System Administrators often deal with dozens of systems at once, so they need a scalable method for merging folders.
As with most automation tasks, we will be using Powershell to achieve this. All we need is a script that goes through the contents of the parent folder, comparing each file name to see if there is a match. You can choose to replace different files or just not overwrite them altogether.
$sourcePath = “C:\Folder1”
$destinationPath = “C:\Folder2”
$files = Get-ChildItem -Path $sourcePath -Recurse -Filter “*.*”
foreach($file in $files){
$sourcePathFile = $file.FullName
$destinationPathFile = $file.FullName.Replace($sourcePath, $destinationPath)
$exists = Test-Path $destinationPathFile
if(!$exists){
$dir = Split-Path -parent $destinationPathFile
if (!(Test-Path($dir))) { New-Item -ItemType directory -Path $dir }
Copy-Item -Path $sourcePathFile -Destination $destinationPathFile -Recurse -Force
}
else{
$isFile = Test-Path -Path $destinationPathFile -PathType Leaf
if(!$isFile){
Copy-Item -Path $sourcePathFile -Destination $destinationPathFile -Recurse -Force
}
}
}
This script uses a loop to recursively copy over the contents of the source folder into the destination folder, leaving the original files untouched in case of a conflict. You can resolve the conflicts differently (by replacing older files, etc.) and use parameters for the source and destination paths to make it more flexible.
Third-Party Applications to Merge Folders Easily
There are a couple of third-party apps that make the process of merging folders much easier. Their complexity ranges from basic GUI merging tools to complete file-comparison software with versioning support.
Here are the best third-party apps for merging folders in Windows 10 and 11:
By itself, Windows cannot compare the contents of identical files while copying. All it can tell you is their file size and date, leaving you to manually determine which file to keep when you run into a duplicate.
WinMerge is an open-source program for comparing files and merging folders in Windows. It is handy for coders and system administrators since it can compare the contents of text files and present them in a visual format.
If you just want a simple GUI-based folder merging tool, 2XDSOFT’s Folder Merger is a good choice. It lets you merge folders and subfolders from an intuitive interface with many customization options.
You can retain the folder structure, use filename filters, or even leave aside particular subfolders. The best part is that the app is portable – you can carry it around in a pen drive and use it directly without installation.
Araxis Merge (Free 30-day Trial; $129 Standard; $269 Professional)
Araxis Merge is a powerful file comparison and merger application for Windows and macOS. Like with WinMerge, it is best for those who work with many text files, such as programmers or legal professionals.
You can consider it a more advanced form of WinMerge, with advanced file comparison, including text, image, and binary files. Version control systems can be directly integrated with Araxis Merge, along with an API to enable automation through the command line.
This extra functionality does not come free. Araxis Merge is a premium tool, requiring you to purchase a license to use it beyond the 30-day trial period. Check out the Araxis Merge site for complete pricing and a detailed list of features in the standard and pro versions.
What is the Best Way to Merge Folders in Windows 10/11?
If you are just looking to merge the contents of two directories into a single folder, then the default method is the best approach. Just open File Explorer, rename one of the folders to the same name, and copy-paste over the other, letting Windows handle the merger.
You only need other methods if you have to merge many folders regularly or need detailed file comparison algorithms. If you are looking to merge text files, there are other methods.
Powershell scripts are probably the most flexible method for this, as cmdlets can be used to combine files based on any number of advanced criteria. The only problem is that it requires a little knowledge of Powershell’s syntax to be able to write the code. But this is the way if you want to set up automated scripts for merging folders.
For a more user-friendly method, you can use a third-party application. Apps like WinMerge and Araxis Merge allow you to compare files and merge folders without needing to be proficient with coding. This makes them essential programs for those who work with text files in bulk.
