最近在我的Windows PC 上浏览我的一些备份文件和文件夹时，我遇到了一些我想删除的旧备份文件。我对旧备份没有任何用处，因此想删除压缩的 .tar 文件。

但是当我继续删除它时，我收到以下错误消息：

文件名对于目标文件夹来说太长了

显然，压缩文件包含一个JPG图像文件，我的Windows无法删除该文件。使用跳过^(Skip)选项，我删除了除此文件之外的所有文件。现在，为什么会发生这种情况？

在标准  Windows文件命名系统下，总名称不能，或路径超过 259 个字符。这包括文件夹路径、文件名和文件扩展名。如果是这样，那么当您尝试删除它时，您将收到此错误。

Maximum Path Length Limitation: In the Windows API (with some exceptions discussed in the following paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260 characters. A local path is structured in the following order: drive letter, colon, backslash, name components separated by backslashes, and a terminating null character. For example, the maximum path on drive D is “D:\some 256-character path string” where “” represents the invisible terminating null character for the current system codepage. (The characters < > are used here for visual clarity and cannot be part of a valid path string) says MSDN.

目标文件夹的文件名^(Filename)太长

现在就我而言，完整的文件夹路径是：

D：Site Backups\ Misc\ backup-4.7.2012_23-41-31_thegadget.tar backup-4.7.2012_23-41-31_thegadget backup-4.7.2012_23-41-31_thegadget homedirect 2 public_html2 wp-content2 上传 2011 08

从图片中可以看出，文件名真的很长——比如Music-producer-...-and-video-games.jpg 。

我打开它的位置并尝试删除或重命名^{(delete or rename)}该文件。我什至没有选择这样做。如果你可以重命名它，很好——但我没有被提供这个选项。

这个简单的技巧在我的案例中很有效，我希望它对你也有帮助。^{(This simple trick worked in my case, and I hope it helps you too.)}

有时简单地重新启动、运行检查磁盘^{(Check Disk)}或使用第三方删除免费软件也有助于删除不可删除的文件和文件夹。

您还可以使用免费软件Long Path Fixer来修复Windows中的^(Windows)Path Too Long 错误。

如果没有任何帮助，那么您可能想看看这个Microsoft 线程^{(Microsoft thread)}，其中建议了一些使用CMD和Robocopy的高级方法。

The file name(s) would be too long for the destination folder

Recently while browsing through some оf my backup files and folders on my Windows PC, I camе across some old backup files that I wanted to delete. I did not have аny use for an old backup, so wаnted to delete the compressed .tar file.

But when I went on to delete it, I received the following error message:

The file name(s) would be too long for the destination folder

Apparently, the compressed file contained a JPG image file, which my Windows was unable to delete. Using the Skip option, I deleted all but this file. Now, why did this happen?

Under standard  Windows file naming system, the total name cannot, or path exceeds 259 characters. This includes the folder path, file name, and file extension. If it does, then when you try to delete it, you will receive this error.

Maximum Path Length Limitation: In the Windows API (with some exceptions discussed in the following paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260 characters. A local path is structured in the following order: drive letter, colon, backslash, name components separated by backslashes, and a terminating null character. For example, the maximum path on drive D is “D:\some 256-character path string” where “” represents the invisible terminating null character for the current system codepage.

Filename too long for destination folder

Now in my case, the full folder path was:

D:\ Site Backups\ Misc\ backup-4.7.2012_23-41-31_thegadget.tar\ backup-4.7.2012_23-41-31_thegadget\ backup-4.7.2012_23-41-31_thegadget\ homedirect\ 2\ public_html2\ wp-content2\ uploads\ 2011\ 08

And the file name was really long to – like Music-producer-…-and-video-games.jpg – as can be seen in the image.

I opened its location and tried to delete or rename the file. I was not even offered the option to do so. If you can rename it, fine – but I wasn’t offered this option.

This simple trick worked in my case, and I hope it helps you too.

Sometimes simply rebooting, running Check Disk or using third-party delete freeware are also known to help delete undeletable files and folders.

You can also use the freeware Long Path Fixer to fix Path Too Long errors in Windows.

If nothing helps, then you may want to have a look at this Microsoft thread where some advanced ways have been suggested using CMD and Robocopy.
