尽管多年来传统硬盘驱动器变得更便宜，但很多人仍然拥有 500 GB 或更小的主驱动器。为什么？好吧，主要是因为较新的计算机带有固态驱动器 ( SSD(SSDs) )，而且更大的尺寸太贵了。
如果您在Windows中收到磁盘空间不足的警告，您可以采取一些措施来恢复一些可用空间。然而，第一件事是实际找出操作系统和您的数据/程序在系统上占用了多少空间。一旦你知道了这一点，你就可以决定删除、删除什么等。
我多年来一直使用的最好的工具是TreeSize free。这是一个您甚至不必安装的小程序，它可以快速准确地告诉您哪些文件和文件夹在您的计算机上占用的空间最多。
如您所见，我计算机上最大的目录是Windows。这对你来说可能也可能不是。如果是这样，减少旧Windows大小的唯一安全方法是使用磁盘清理。如果您有一个较大的 Windows.old 文件夹(large Windows.old folder)，请务必阅读我关于如何使用磁盘清理(Disk Cleanup)将其删除的帖子。
如果您发现Windows目录下有一个很大的驱动程序文件夹，并且恰好有很多与您的显卡（Nvidia，AMD）相关的文件，那么您应该运行Display Driver Uninstaller工具，它为我节省了很多GB(GBs)的空间. 由于某些原因，NVidia等在升级旧版本时会保留以前版本的驱动程序，这会增加很多空间。
下一个最大的文件夹可能是Program Files或Users文件夹。如果Program Files非常大，请将其展开并查看是否有您不再需要并且可以卸载的程序。我还写了一篇关于可以帮助您卸载新 PC 附带的所有垃圾软件的程序的文章。(uninstall all the junk software)
就 PC 上的单个文件而言，对我来说最大的文件是 hiberfil.sys。这是用于休眠的文件，但是，如果您不使用休眠，则可以删除此文件并节省几GB(GBs)的空间。阅读我之前关于如何轻松删除休眠文件的文章。
在Users文件夹下，可以更轻松地删除任何占用大量空间的个人项目，例如照片、视频等。但是，您可能还会发现AppData/Local文件夹非常大。这是一个隐藏的系统文件夹，各种程序使用它来存储临时数据和应用程序数据。
缩小此文件夹大小的最佳方法是使用CCleaner之类的工具。您不想手动进入并从中删除内容，因为它可能会导致您的程序和操作系统出现问题。我已经写了一篇关于这些类型的清洁器是否真的有用的深入文章，但底线是CCleaner在删除难以找到的临时数据方面做得很好。
我还写了另一篇文章，介绍了节省计算机空间的不同方法，即检查回收站大小以及分配给系统还原的空间量。
另一个可能出现的问题是，如果您的 C 驱动器分区开始时非常小。也许您有一个 500GB 的磁盘，但由于某种原因，系统分区 (C) 的大小只有 30 GB。在这些类型的情况下，如果扩展分区上有可用空间，则实际上可以扩展分区的大小。
最好的方法是使用像Easeus Free Partition Manage r 这样的免费工具。他们有各种方法可以尝试让您购买升级版，但免费版应该适用于大多数人。
除了用更大的硬盘替换硬盘之外，实际上没有很多其他方法可以释放硬盘空间，但希望在此之前，上述一些技巧会给您一些喘息的空间。享受！
How to Fix a Low Disk Space Warning in Windows
Even though tradіtional hard drіveѕ have gotten cheaper over the years, a lot оf people still have primary drives that are 500 GB or less in size. Why? Well, moѕtly because newer computers come with solid stаtes drives (SSDs) and the larger sizes are just too expensive.
If you’re getting a low disk space warning in Windows, there are a couple of things you can do to get some free space back. The first thing, however, is to actually find out how much space the operating system and your data/programs are taking up on the system. Once you know that, you can decide what to remove, delete, etc.
The best tool for I’ve been using for years is TreeSize free. It’s a small program that you don’t even have to install and it quickly tells you exactly what files and folders are taking up the most space on your computer.
As you can see, the biggest directory on my computer is Windows. This may or may not be the case for you also. If it is, the only safe way to reduce the size of the Windows older is to use disk cleanup. If you have a large Windows.old folder, make sure to read my post on how to remove it using Disk Cleanup.
If you find there is a large drivers folder under the Windows directory and it happens to have a lot of files related to your graphics card (Nvidia, AMD), then you should run the Display Driver Uninstaller tool, which saved me many GBs in space. For some reason, NVidia and the like keep previous versions of the drivers when you upgrade the old versions, which can add up to a lot of space.
The next largest folder will probably be either Program Files or the Users folder. If Program Files is very large, expand it and see if there are any programs that you no longer need and can uninstall. I’ve also written an article about a program that can help you uninstall all the junk software that comes with new PCs.
In terms of individual files on a PC, the largest one for me was hiberfil.sys. This is the file used for hibernation, however, if you don’t use hibernation, then you can remove this file and save several GBs worth of space. Read my previous article on how to delete the hibernation file easily.
Under the Users folder, it’ll be easier to remove any personal items that are taking up a large amount of space like photos, videos, etc. However, you may also find that the AppData/Local folder is quite large. This is a hidden system folder that is used by various programs to store temporary and app data.
The best way to shrink the size of this folder is to use a tool like CCleaner. You don’t want to manually go in and delete stuff from there as it can cause problems with your programs and with the OS. I’ve written an in-depth article on whether or not these types of cleaners are actually useful, but the bottom line is that CCleaner does an excellent job of removing the hard-to-find temp data.
I’ve also written another article that takes about different ways you can save space on your computer, namely checking the recycle bin size and also the amount of space allocated to system restore.
Another issue that can come up is if your C drive partition is very small to start off with. Maybe you have a 500GB disk, but for some reason, the system partition (C) is only 30 GB in size. In these types of cases, you can actually expand the size of the partition if you have free space on the extended partition.
The best way to do this is to use a free tool like Easeus Free Partition Manager. They have all kinds of ways to try and get you to purchase the upgraded version, but the free version should work for most people.
There aren’t really a lot of other ways to free up space on a hard drive other than replacing it with a bigger one, but hopefully some of the above tips will give you some breathing room till then. Enjoy!
