在以前的Windows版本中，保存文件是一场灾难（至少在无意中如此）。除了系统还原(System Restore)之外，Windows没有用于回滚对文件的意外更改的内置选项。除非您设法使用新文件名保存文件，否则文件的原始版本会丢失。
意识到这是一个问题，Microsoft引入了File History，该功能允许您回滚对文件的更改，但如果您更喜欢使用第三方解决方案，还有其他选择。要在Windows 10(Windows 10)中恢复以前版本的文件，您需要执行以下操作。
使用文件历史记录恢复以前版本的文件(Restore Previous Versions of Files Using File History)
如果要回滚对文件的更改并恢复以前的版本，最好的方法是使用 Windows 自己的文件版本控制功能。您需要首先启用文件历史记录(File History)，它通常使用外部驱动器（或在某些情况下是网络驱动器）来存储文件。(networked drive)
如果未启用文件历史记录(File History)，则您可能无法在Windows 10中恢复以前的版本，除非您已经将文件同步到云存储(syncing your files to cloud storage)。
- 您可以检查是否在Windows 设置(Windows Settings )菜单中启用了文件历史记录。(File History)右键单击(Right-click)“开始(Start)”菜单并选择“设置”(Settings)选项开始。
- 在Windows 设置(Windows Settings )菜单中，选择Update & Security > Backup。在“使用文件历史(Back up using File History )记录备份”选项下方，将列出您当前用于文件历史记录备份的驱动器。(File History)如果未列出，则需要通过选择添加驱动器(Add a drive )选项来启用文件历史记录。(File History)
- 可用外部驱动器列表将出现在下拉菜单中。选择其中(Select one)之一以启用文件历史记录(File History)。备份(Backup )菜单将更新一个滑块，允许您在完成此操作后打开和关闭文件历史记录。(File History)您可以通过选择滑块下方的更多选项(More options )来选择它监控的文件夹。
- 在更多选项(More options )菜单中，您可以通过选择备份这些文件夹(Back up these folders )类别下的添加文件夹(Add a folder )选项来添加或删除文件夹以监视文件历史记录。(File History)
- 您还可以更改备份文件的频率以及存储备份的频率。要更改这些设置，请使用备份我的文件(Back up my files )和保留我的备份(Keep my backups )下拉菜单更改设置。
- 启用文件历史记录(File History)并监控正确的文件夹后，您可以使用Windows 文件资源管理器(Windows File Explorer)恢复以前版本的文件。这仅适用于您在启用文件历史记录(File History)后编辑的文件。(after) 为此，请打开文件资源管理器(File Explorer)并找到包含您要恢复的文件的文件或文件夹。右键单击文件或文件夹，然后选择恢复以前的版本(Restore previous versions )选项。
- 在“属性”窗口的“(Properties)以前的版本(Previous Versions)”选项卡中，您将看到文件或文件夹的以前版本的列表。要查看文件或文件夹，请从列表中选择要恢复的版本，然后选择底部的打开按钮。(Open)如果要恢复它，请选择恢复(Restore )。
- 如果您选择恢复(Restore)，以前保存的文件将覆盖新文件。要保存两个副本，请先选择“还原”(Restore )按钮旁边的向下箭头(downwards arrow )，然后选择“还原到”(Restore To)。
- 选择一个新文件夹以保存文件的先前版本，然后选择“选择文件夹(Select Folder )”选项。
Windows文件资源管理器(File Explorer)将打开以向您显示恢复的文件，无论您选择覆盖新副本还是将它们保存在其他位置。正如我们所提到的，此选项仅在您对文件进行更改之前(before)启用了文件历史记录时才有效。(File History)
不幸的是，如果您还没有备份系统(backup system)，则没有很多选项可以帮助您在Windows 10中恢复以前的版本。但是，如果您删除了该文件，您可能会更幸运，因为Microsoft现在提供了一个Windows 文件恢复工具(Windows File Recovery tool)来帮助恢复丢失的文件。
使用第三方文件版本控制软件(Using Third Party File Versioning Software)
Windows文件历史记录(File History)是文件版本控制的绝佳选择，但它依赖于使用外部驱动器进行备份，并且备份限制为每 15 分钟一次。虽然它确实支持网络驱动器，但对此的支持似乎确实存在更多问题，具体取决于您的网络配置方式。
考虑到这一点，您可能更喜欢使用第三方文件版本控制软件。虽然存在付费选项，但适用于Windows(Windows)的最简单的文件版本控制应用程序之一是AutoVer，这是一款免费应用程序，可让您定期将文件备份到外部驱动器、网络连接的存储驱动器和异地FTP服务器。
- 首先，在您的 Windows PC 上下载并安装AutoVer 。安装软件后，您可以通过选择 AutoVer 客户端中的添加新观察(Add New Watcher )程序图标开始监视某些文件夹。
- 您需要确定要监控的文件夹以及保存文件备份的位置。在名称(Name )框中为您的监控规则提供一个名称。在Watch Folder下，提供您要监控的文件夹或驱动器的位置。最后，在“备份到(Backup To)”框中提供保存备份的位置。您可以选择使用外部驱动器等本地备份位置，或通过FTP切换到备份文件，方法是在“(FTP)备份类型(Backup Type )”选项之间进行选择。
- 在版本控制(Versioning )选项卡中，您可以选择希望保存备份文件的时间。如果您计划备份到远程服务器，您可以在FTP选项卡中设置您的FTP连接设置。对更改感到满意后，选择“确定(OK)”按钮保存更改。
- AutoVer将自动备份您对文件所做的任何更改，几乎在您进行更改后立即进行备份。但是，要立即运行观察程序规则并开始新的备份，请选择Synchronize the selected Watcher (Backup now!) 按钮。
- 如果要查看备份的文件，可以通过右键单击观察程序规则并选择“浏览备份”(Explore backups)选项来执行此操作。这将打开AutoVer 文件资源管理器(AutoVer File Explorer)，允许您查看已保存的文件。如果要恢复文件的早期版本，可以选择其中一个版本，在右侧栏中选择一个过时的版本，然后选择“恢复文件”(Restore File)按钮。
虽然AutoVer可能看起来有点过时，但它在定期备份文件并为您提供Windows 10中文件版本控制的第三方选项方面非常出色。文件几乎立即备份，让您快速恢复对可能被错误更改的文件所做的更改。
虽然Google Drive(Google Drive)等云存储服务是替代选项，但您受限于文件版本的存储频率。这使得无限制的文件版本控制（如AutoVer提供的版本）成为长期备份的卓越解决方案。
确保您的 Windows 10 文件安全(Keeping Your Windows 10 Files Safe)
您的 PC 不会永远使用下去，因此始终牢记Windows备份系统非常重要。如果您开始使用非现场云存储（如Google Backup and Sync(Google Backup and Sync)）来存储文件副本， 则在Windows 10中恢复以前版本的文件会容易得多。
但是，如果您只担心回滚小的更改，那么 Windows 的内置文件历史记录应该可以正常工作，但您可以使用AutoVer等工具更定期地保存文件版本。如果您错误地删除了文件，您可以使用Shadow Explorer 等第三方软件(third-party software like Shadow Explorer)来检索它们。
How to Restore Previous Versions of Files in Windows 10
In previous versions of Windows, saving over a file wаs a dіѕaster (at least when it was unintended). Beyond System Restore, Windows had no built-in options for rolling back accidental changes to files. The original version of your file was lost unless you’d managed to save it with a new filename.
Realizing this was an issue, Microsoft introduced File History, a feature that allows you to roll back changes to your files, but there are alternatives if you’d prefer to use a third-party solution. To restore previous versions of files in Windows 10, here’s what you’ll need to do.
Restore Previous Versions of Files Using File History
If you want to roll back the changes to a file and restore a previous version, the best way to do it is to use Windows’ own file versioning features. You’ll need to have enabled File History first, which typically uses an external drive (or networked drive in some cases) to store the files.
If File History isn’t enabled, then you may not be able to restore a previous version in Windows 10 unless you’re already syncing your files to cloud storage.
- You can check if File History is enabled in the Windows Settings menu. Right-click the Start menu and select the Settings option to begin.
- In the Windows Settings menu, select Update & Security > Backup. Underneath the Back up using File History option, the drive you currently use for File History backups will be listed. If one isn’t listed, then you’ll need to enable File History by selecting the Add a drive option.
- A list of available external drives will appear in a drop-down menu. Select one of these to enable File History. The Backup menu will update with a slider allowing you to switch File History on and off once you’ve done this. You can select which folders it monitors by selecting More options underneath the slider.
- In the More options menu, you can add or remove folders to monitor for File History by selecting the Add a folder option underneath the Back up these folders category.
- You can also change how often files are backed up and how often the backups are stored for. To change these settings, change the settings using the Back up my files and Keep my backups drop-down menus.
- Once File History is enabled and monitoring the correct folders, you can restore previous versions of files using Windows File Explorer. This will only work for files you edit after File History has been enabled. To do this, open File Explorer and find the file or folder containing the file you wish to restore. Right-click the file or folder, then select the Restore previous versions option.
- In the Previous Versions tab of the Properties window, you’ll see a list of previous versions of your file or folder. To view the file or folder, select the version you want to restore from the list, then select the Open button at the bottom. If you want to restore it, select Restore instead.
- If you select Restore, the previously saved files will overwrite the new files. To save both copies, select the downwards arrow next to the Restore button first, then choose Restore To instead.
- Select a new folder to save the previous versions of your files, then select the Select Folder option.
Windows File Explorer will open to show you the restored files, whether you selected to overwrite the new copies or save them elsewhere instead. This option, as we’ve mentioned, only works if you had File History enabled before you made changes to files.
Unfortunately, there aren’t many options to help you restore previous versions in Windows 10 if you don’t already have a backup system in place. You may have more luck if you deleted the file, however, as Microsoft now offers a Windows File Recovery tool to help recover lost files.
Using Third Party File Versioning Software
Windows File History is a great option for file versioning, but it relies on using an external drive for backups, and backups are limited to every 15 minutes. While it does support network drives, support for this does seem to be more problematic, depending on how your network is configured.
With that in mind, you may prefer to use third-party file versioning software instead. While paid options exist, one of the simplest file versioning apps for Windows is AutoVer, a free app that will allow you to regularly back up your files to external drives, network attached storage drives, and offsite FTP servers.
- To start, download and install AutoVer on your Windows PC. Once the software is installed, you can begin to monitor certain folders by selecting the Add New Watcher icon in the AutoVer client.
- You’ll need to identify the folder you wish to monitor, as well as the location to save the file backups. Provide a name for your monitor rule in the Name box. Under Watch Folder, provide the location of the folder or drive you wish to monitor. Finally, provide a location to save the backups in the Backup To box. You can choose to use a local backup location like an external drive, or switch to backup files over FTP, by choosing between the Backup Type options.
- In the Versioning tab, you can select how long you wish to save your backup files for. If you plan on backing up to a remote server, you can set your FTP connection settings in the FTP tab. Once you’re happy with the changes, select the OK button to save your changes.
- AutoVer will automatically back up any changes to your files, almost as soon as you make changes. To run the watcher rule immediately and begin a new backup, however, select the Synchronize the selected Watcher (Backup now!) button.
- If you want to view backed up files, you can do so by right-clicking the watcher rule and selecting the Explore backups option. This will open AutoVer File Explorer, allowing you to view the files that have been saved. If you want to restore an earlier version of a file, you can select one of the versions of it, selecting a dated version in the right-hand column, then selecting the Restore File button.
While AutoVer may look a little dated, it works incredibly well in regularly backing up your files and giving you a third-party option for file versioning in Windows 10. Files are backed up almost immediately, letting you quickly recover changes to files that may have been changed by mistake.
While cloud storage services like Google Drive are alternative options, you’re limited to how often versions of the file can be stored for. This makes unlimited file versioning, like those offered by AutoVer, a superior solution for long-term backups.
Keeping Your Windows 10 Files Safe
Your PC won’t last forever, so it’s important to always have a backup system in mind for Windows. Restoring previous versions of files in Windows 10 is much easier if you begin using offsite cloud storage, like Google Backup and Sync, to store copies of your files.
If you’re only worried about rolling back small changes, however, then Windows’ built-in file history should work well, but you can save versions of files more regularly using tools like AutoVer. If you’ve deleted files by mistake, you may be able to retrieve them using third-party software like Shadow Explorer.
