随着我们继续使用 Windows 11/10/8/7 PC，我们倾向于积累大量文件、图像和音乐。大量文件可能会导致重复，尤其是在图像和音乐方面。这些文件在 PC 上占用大量空间，并且不容易找出重复文件并手动删除它们。
查找和删除重复文件
重复文件(Duplicate files)是个问题，因为您不知道哪个文件包含最新内容。在协作的情况下，如果您打开错误的文档，您可能会错过同事对文档所做的更改。最坏的情况可能是您和您的同事不知道重复项，并且你们都在处理不同版本的文件。
尽管有Comodo System Cleaner和CCleaner等垃圾清理工具，但它们无法识别和修复重复文件的问题。因此(Hence)，您需要可以搜索、删除和合并重复文件的专用软件。
重复文件查找器(Duplicate File Finder)和卸妆(Remover)软件
本文讨论了三个这样的免费软件，它们将帮助您在Windows 10/8/7中查找和删除或删除重复文件。以下(Below)是可帮助您删除Windows 10 PC 上重复文件的软件列表。有些是完全免费的，而有些则有PRO版本，可以帮助您做更多事情并更准确地查找文件。
1] 双杀
从名称可以看出，DoubleKiller从您的计算机中查找并删除重复文件。Big Bang Enterprises的软件有两个版本。一个是免费使用的，你必须为另一个版本付费。当然，付费版的工作量更大，但您也可以借助免费软件获得良好的效果。
该软件使用包括哈希比较在内的方法来比较文件。这个软件(This software)好用，所以我把它放在第一位。
2]AllDup
它是一款功能强大、功能丰富的软件，可以查找和删除重复文件。你当然可以复制，也可以移动。该工具的丰富之处之一是查找具有不同ID3 标签的重复(ID3 Tags)MP3文件。它有许多选项和过滤器来比较MP3文件和图像的内容，而不是不同的元数据，例如ID3 标签(ID3 Tag)。
除此之外，该软件的另一个独特功能是它可以让您比较两个文件夹中的重复文件。您可以选择与一个源文件夹或文件夹内的文件进行比较，或者在不同的源文件夹之间进行比较。如果您有在多个地方维护副本的习惯，那么稍后(Later)将非常有用。从这里(from here.)下载。
3] 欺骗大师
最新版本的 dupeGuru被称为 dupeGuru音乐版(Music Edition)，与功能集相比，它添加了音乐文件。
除了删除具有相似文件名的重复文件外，该免费软件(this freeware)还具有在文件中搜索的能力——尤其是MP3——(MP3s –)即使文件名不同，也可以知道它们是否相似。它为您提供搜索结果，允许您选择保留哪一个和丢弃哪一个。
4]来自数字火山的(Digital Volcano)重复清洁剂(Duplicate Cleaner Free)
它提供了一个具有专业外观的界面，其中包含查找重复文件的高级选项。可以按大小、日期、修改日期的形式查找，使用文件过滤器（通配符），排除已知文件。了解这部分的高级(Advanced)用户可以选择排除NTFS挂载点和连接。您还可以使用其内置的文件资源管理器设置搜索位置。
下载此软件时，请查找“ Duplicate Cleaner(Duplicate Cleaner)的基本、轻量版，仅供非商业用途” 。 下载页面预先为您提供了专业版，但对于家庭使用，精简版绰绰有余。
专业版会告诉您它们是否相似，并且还可以进行逐字节+算法。它还提供图像模式和音频模式。音频模式非常有趣。它可以根据ID3标签查找文件，但它们仅在Pro模式下可用。从这里( here)下载。
5] 合并
WinMerge是一个跨平台的跨平台软件。相同的软件可以在Windows和 Linux上使用。您无需安装该软件，因此您可以直接从您的笔式驱动器启动它——如果您愿意的话。搜索和合并功能可帮助您保留具有几乎相似内容的所有重复文件的混合。WinMerge的图形用户界面(GUI)很好，可以很容易地找到不同文件之间的相似之处。WinMerge将在(WinMerge)Windows中显示视觉差异并合并文件和文件夹。在这里(here)得到它。
6] Auslogics 重复文件查找器
这个来自Auslogics马厩的免费软件将帮助您查找和删除存储在 Windows PC 上的无用重复文件。它是另一款设计精美的软件，可以在您的 Windows 10 PC 上找到重复的图像、音频文件、视频、档案和应用程序。我非常喜欢它的一些功能。首先(First)，它确保备份您计划删除的所有内容，其次，它默认忽略一组系统文件和文件夹。
也就是说，一旦您搜索，结果就会以具有突出显示颜色的组的形式显示。这很容易理解。结果可以按日期和类型过滤，然后您可以选择按修改日期仅选择重复文件，仅选择一组，等等。
特征：
- 查找(Finds)相同的图片、文档和任何其他文件
- 不仅按名称比较文件，还按内容比较文件
- 可以显着增加磁盘上的可用空间
- 帮助(Helps)您组织您的媒体收藏
- 减少对硬盘进行碎片整理所需的时间

7]重复文件橡皮擦
Duplicate File Eraser提供简单但微小的细节，您可以接管以查找重复文件。您可以搜索目录、子目录、隐藏文件以及系统文件（尽管忽略）以查找重复文件。您可以在CRC32、MD5、SHA1文件比较算法之间进行选择。如果您想根据大小、类型名称等查找文件，则可以。它还可以搜索隐藏文件，但请确保对您拥有的文件夹执行此操作，而不是使用系统文件夹。
8] Dupscout重复查找器
DupScout是一个高级的重复文件查找器，它可以在找到重复文件后做很多事情。不是每个人都想删除重复文件，如果你想将它移动到目录或压缩它，(if you want to move it a directory or compress it,)你可以这样做。它甚至可以 通过简单地输入 IP 地址来扫描服务器或 NAS 设备。(scan Servers or NAS devices)搜索文件时，您可以为扫描过程创建规则(create rules for the scanning process)。最后，它会根据文件的类型生成一个特殊的报告，让您了解占用的存储空间。
9] 无克隆
NoClone是另一个免费软件，它使用实时逐字节比较来检测重复文件，而不管它们的文件名如何。您可以将搜索限制为特定的文件类型（图像、程序等）以及大小、日期和位置。
该软件使用实时的逐字节比较来查找确切的内容而不是相关的内容。最好的部分是它支持过多的文件扩展名，包括 s docx、xlsx、pptx；音频文件、视频文件、Outlook电子邮件等。为了找到相似的图像，它使用了模糊搜索算法。免费版本在单个会话中限制为 300,000 个文件。NoClone的免费版在单个会话中限制为 300,000 个文件。
此类别中的其他类似免费软件有：(Other similar freeware in this category are:)
如果您需要查找重复的图像，请尝试Awesome Duplicate Photo Finder。
警告：(Warning:)从 PC 中删除文件时，请务必小心。如果在PC上到处发搜索，很有可能会删除系统镜像，导致系统不稳定。所以，要非常非常小心。

Τheѕe files take a lot of space on thе PC, and thеy are not easy to figure out the duplicate files аnd deletе them manually.
Find and remove duplicate files
Duplicate files are a problem, as you do not know which one contains the most current content. In the case of collaborating, you may miss out on changes your co-worker did to the document if you open the wrong one. The worst-case scenario may be that you and your colleagues do not know about duplicates and you all work on different versions of the file.
Though there are junk cleaners such as the Comodo System Cleaner and CCleaner, they fail to recognize and fix the problem of duplicate files. Hence you need dedicated software that can search and remove and merge duplicate files.
Duplicate File Finder & Remover software
This article talks about three such free software which will help you find and delete or remove duplicate files in Windows 10/8/7. Below is the list of software that can help you remove duplicate files on the Windows 10 PC. Some are completely free, while some have a PRO version that helps you do more, and find files more accurately.
1] DoubleKiller
As evident by the name, DoubleKiller finds and removes duplicate files from your computer. The software from Big Bang Enterprises is available in two editions. One is free to use, and you have to pay for the other edition. Of course, the paid edition does more work, but you can get good results with the help of freeware too.
The software uses methods including a hash comparison to compare files. This software is easy to use, and hence I placed it in the first position.
2] AllDup
It’s a powerful software, feature-rich, which can find, and delete duplicate files. You can of course copy, and move as well. One of the riches aspects of this tool is finding duplicate MP3 files with different ID3 Tags. It has many options and filters to compare MP3 files and images by their content, rather different metadata such as ID3 Tag.
Apart from this, another unique feature of this software is that it lets you compare two folders for duplicate files. You can choose to compare with one source folder or files within the folder or between different source folders. Later is very useful if you have a habit of maintaining copies at multiple places.

3] dupeGuru
Known popularly as the dupeGuru Music Edition, the latest version of dupeGuru adds music files in comparison to the feature set.
In addition to removing duplicate files with similar filenames, this freeware also has the capability to search within files – especially MP3s – to know if they are similar even in case the filenames are different. It presents you with the search results allowing you to select which one to keep and which one to discard.
4] Duplicate Cleaner Free from Digital Volcano
It offers a professional-looking interface with advanced options to find duplicate files. You can find in the form of by size, date, modified date, use file filter (wildcards), and exclude known files. Advanced users, who understand this part, can choose to exclude NTFS mount points and junctions. You can also set locations for searches using its inbuilt file explorer.
When you download this software, look for “A basic, light version of Duplicate Cleaner, for Non-Commercial use only”. The download page offers you a pro version up front, but for home usage, the light version is more than enough.
The pro version tells you if they are alike and also can do byte-to-byte+algorythms. It also offers image mode and audio mode. The audio mode is very interesting. It can find files based on ID3 tags, but they are available only in Pro mode. Download it from here.

The GUI of WinMerge is good and makes it easy to locate similarities among different files. WinMerge will display visual differences & merge files & folders in Windows. Get it here.
6] Auslogics Duplicate File Finder
This freeware from the stables of Auslogics will help you to find and remove useless duplicate files, stored on your Windows PC. It’s another brilliantly designed software that can find duplicate images, audio files, video, archives, and applications on your Windows 10 PC. There are features which I absolutely loved about it. First, it makes sure to backup everything you plan to delete, and second, it ignores a set of system files and folders by default.
That said, once you search, the results are displayed in form of groups with highlighted colors. This makes it easy to understand. The results can be filtered by date and type, and you can then choose to select only duplicate files by modified date, select only one group, and so on.
Features:
- Finds identical pictures, documents, and any other files
- Compares files not only by names but by their content
- Can significantly increase free space on your disk

If you want to find files based on size, type name, etc., it is possible. It can also search hidden files, but make sure to do it for folders that you own, and not use the system folders.
8] Dupscout Duplicate Finder
DupScout is an advanced duplicate file finder which can do a lot of things after it finds the duplicate file. Not everyone wants to delete the duplicate file, and if you want to move it a directory or compress it, you can do that. It can even scan Servers or NAS devices by simply entering their IP addresses. When searching for a file, you can create rules for the scanning process. In the end, it will generate a special report which gives you an idea of the storage space occupied, according to the type of file.

The best part is that it supports a plethora of file extensions including s docx, xlsx, pptx; audio files, video files, Outlook emails, and more.
