在 Windows 中删除大文件夹的最快方法是什么?

发布于 2024-07-07 17:21:46 字数 183 浏览 7 评论 0原文

我想删除一个包含数千个文件和文件夹的文件夹。 如果我使用 Windows 资源管理器删除该文件夹,可能需要 10-15 分钟(并非总是如此,但经常)。 Windows 中有没有更快的方法来删除文件夹?

其他细节:

  • 我不关心回收站。
  • 这是一个 NTFS 驱动器。

I want to delete a folder that contains thousands of files and folders. If I use Windows Explorer to delete the folder it can take 10-15 minutes (not always, but often). Is there a faster way in Windows to delete folders?

Other details:

  • I don't care about the recycle bin.
  • It's an NTFS drive.

最糟糕的方法是发送到回收站:您仍然需要删除它们。 其次最糟糕的是使用 Windows 资源管理器执行 Shift+Delete:它会浪费大量时间在开始删除任何内容之前检查内容。

接下来最好的方法是从命令行使用 rmdir /s/q 文件夹名称 。 del /f/s/qfoldername 也很好,但它留下了目录结构。

我发现的最好的是一个两行批处理文件,第一遍删除文件并输出到 nul,以避免为每个单个文件写入屏幕的开销。 然后,第二遍清理剩余的目录结构:

del /f/s/q foldername > nul
rmdir /s/q foldername

这比单个 rmdir 快近三倍,基于 Windows XP 加密磁盘的时间测试,删除约 30GB/1,000,000 个文件/15,000 个文件夹:rmdir 大约需要 2.5 小时,del+rmdir 大约需要 53 分钟。 更多信息请访问超级用户

这对我来说是一项常规任务,因此我通常将需要删除的内容移至 C:\stufftodelete 并将这些 del+rmdir 命令放在 deletestuff.bat 批处理文件中。 这计划在晚上运行,但有时我需要在白天运行它,所以越快越好。

可以找到 del 命令的 Technet 文档 这里。 有关上面使用的参数的附加信息:

  • /f - 强制(即删除文件,即使它们是只读的)
  • /s - 递归/包含子文件夹(此定义来自 < a href="https://ss64.com/nt/del.html" rel="noreferrer">SS64,因为 technet 只是声明“指定文件”,这没有帮助)。
  • /q - 安静(即不提示用户确认)

rmdir 的文档 此处。 参数为:

  • /s - 递归(即与 del 的 /s 参数相同)
  • /q - 安静(即与 del 的 /q 参数相同)

The worst way is to send to Recycle Bin: you still need to delete them. Next worst is shift+delete with Windows Explorer: it wastes loads of time checking the contents before starting deleting anything.

Next best is to use rmdir /s/q foldername from the command line. del /f/s/q foldername is good too, but it leaves behind the directory structure.

The best I've found is a two line batch file with a first pass to delete files and outputs to nul to avoid the overhead of writing to screen for every singe file. A second pass then cleans up the remaining directory structure:

del /f/s/q foldername > nul
rmdir /s/q foldername

This is nearly three times faster than a single rmdir, based on time tests with a Windows XP encrypted disk, deleting ~30GB/1,000,000 files/15,000 folders: rmdir takes ~2.5 hours, del+rmdir takes ~53 minutes. More info at Super User.

This is a regular task for me, so I usually move the stuff I need to delete to C:\stufftodelete and have those del+rmdir commands in a deletestuff.bat batch file. This is scheduled to run at night, but sometimes I need to run it during the day so the quicker the better.

Technet documentation for del command can be found here. Additional info on the parameters used above:

  • /f - Force (i.e. delete files even if they're read only)
  • /s - Recursive / Include Subfolders (this definition from SS64, as technet simply states "specified files", which isn't helpful).
  • /q - Quiet (i.e. do not prompt user for confirmation)

Documentation for rmdir here. Parameters are:

  • /s - Recursive (i.e. same as del's /s parameter)
  • /q - Quiet (i.e. same as del's /q parameter)

使用 Windows 命令提示符:

rmdir /s /q folder

使用 Powershell:

powershell -Command "Remove-Item -LiteralPath 'folder' -Force -Recurse"

请注意,在更多情况下,delrmdir 会给您留下剩余文件,而 Powershell 会设法删除这些文件。

Using Windows Command Prompt:

rmdir /s /q folder

Using Powershell:

powershell -Command "Remove-Item -LiteralPath 'folder' -Force -Recurse"

Note that in more cases del and rmdir wil leave you with leftover files, where Powershell manages to delete the files.

使用免费工具fastcopy
它有一个删除选项,比 Windows 删除文件的方式快得多。

use fastcopy, a free tool.
it has a delete option that is a lot faster then the way windows deletes files.

按照建议使用命令提示符。 我不久前就弄清楚了为什么资源管理器这么慢,它可以让您估计删除文件/文件夹需要多长时间。 为此,它必须扫描物品的数量和尺寸。 这需要很长时间,因此对于大文件夹的等待是可笑的。

此外,如果文件存在特定问题,资源管理器将停止,

use the command prompt, as suggested. I figured out why explorer is so slow a while ago, it gives you an estimate of how long it will take to delete the files/folders. To do this, it has to scan the number of items and the size. This takes ages, hence the ridiculous wait with large folders.

Also, explorer will stop if there is a particular problem with a file,

要删除大量文件夹,您还可以使用发布的命令 spdenne 创建批处理文件。

1) 创建一个包含以下内容的文本文件,将引号中的文件夹名称替换为您的文件夹名称:

rmdir /s /q "My Apps"  
rmdir /s /q "My Documents"  
rmdir /s /q "My Pictures"  
rmdir /s /q "My Work Files"

2) 使用 .bat 扩展名保存批处理文件(例如,deletefiles.bat)
3)打开命令提示符(开始>运行>Cmd)并执行批处理文件。 您可以从命令提示符执行此操作(用 X 替换驱动器号):

X:  
deletefiles.bat

and to delete a lot of folders, you could also create a batch file with the command spdenne posted.

1) make a text file that has the following contents replacing the folder names in quotes with your folder names:

rmdir /s /q "My Apps"  
rmdir /s /q "My Documents"  
rmdir /s /q "My Pictures"  
rmdir /s /q "My Work Files"

2) save the batch file with a .bat extension (for example deletefiles.bat)
3) open a command prompt (Start > Run > Cmd) and execute the batch file. you can do this like so from the command prompt (substituting X for your drive letter):

X:  
deletefiles.bat

尝试Shift + 删除。 2 分钟内为我处理了 24.000 个文件。

Try Shift + Delete. Did 24.000 files in 2 minutes for me.
