This is why you should always avoid making folders and files with long names and always give priority to use characters with no special encoding (for example always simple english characters).

In this case you need a way to fetch your data from your HDD with a tool because copy-paste won't work due to your cache memory being unable to load the file path information from within your OS.
If you use windows you can try recovery tools like "Active@ File Recovery"

Use Robocopy to copy the files! (Robocopy is ALSO useful for deleting files/folders that are too long. 

Run this from the cmd prompt:

<pre><code>robocopy C:\source\folder K:\destination\folder /e
</code></pre>

This just copies source folder to destination, and the /e switch copies subfolders, including empty directories. <a href="http://social.technet.microsoft.com/wiki/contents/articles/1073.robocopy-and-a-few-examples.aspx" rel="nofollow">More info and examples</a>.

blocks|key|1676514|text|当您将具有有效路径名<255个字符的文件夹复制到子文件夹中，使路径名的总长度大于255时，就会发生这种情况。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1676515|例如，我有一个名为C:...\mypath\thecompletepathtothisfolderis254characters的文件夹，我将其移动或复制到:+C:...\mylongerpath\thecompletepathtothisfolderis254characters，现在路径名增加了6个字符，并打破了255个字符的限制。|1676516|解决方案是将文件夹移回目录树的更高位置，以便路径名再次有效。然后，您可以将其重命名为较短的名称并将其移回原处，或者只需将其保留在原来的位置即可。|1676517|在没有超过255个字符限制的情况下，机器人复制和其他软件将识别这些文件。|1676518|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

This can happen when you copy a folder with a valid pathname &lt;255 characters into a subfolder, making the total length of the pathname greater than 255.

For example I have a folder named
C:...\mypath\thecompletepathtothisfolderis254characters
and I move or copy it to:
C:...\mylongerpath\thecompletepathtothisfolderis254characters
Now the pathname is 6 characters longer and breaks the 255 character limit.

The solution is to move the folder back higher up the directory tree so the pathname is valid again. You can then rename it as a shorter name and move it back, or you can just keep it where it is.

With the 255 character limit not exceeded, robocopy and other software will then recognize the files.

The 255-character path limit in Windows is a legacy limitation that originated from the MS DOS era and was kept for compatibility reasons.
If you have Windows 10 Pro or Windows 11 Pro, then you can partially remove the limit via the Group Policy Editor and/or Registry Editor. Full support is still a work in progress, so you should also update your OS to the latest version if possible.
Important note: Because File Explorer uses an older Windows API, it's still subject to the path limit. However, third-party tools like <a href="https://github.com/git-guides/install-git" rel="nofollow noreferrer">Git</a> (and sed?) are able to avoid this limit. There are probably some visual tools that can do so as well.
To enable partial Windows support, go to <code>Local Computer Policy</code> &gt; <code>Computer Configuration</code> &gt; <code>Administrative Templates</code> &gt; <code>System</code> &gt; <code>Filesystem</code> and look for a setting named <code>Enable Win32 long paths</code>. If you don't see it, then you may need to check in the NFTS subfolder.
<a href="https://i.stack.imgur.com/oBCbu.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/oBCbu.png" alt="enter image description here" /></a>
After that, go to the Registry Editor, navigate to <code>HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem</code>, and create a regular DWORD entry named <code>LongPathsEnabled</code> with a value of <code>1</code>.

I'm not sure if restarting your PC afterwards is required, but it probably wouldn't hurt.

I have an external HDD. The external HDD has only 1 NTFS primary partition. There are some files on it, but I have many folders. There are folders in those folders, folders in those folders etc... 

When I try to copy the files from the external HDD to a NTFS partition on my internal HDD, some files are not copied because their file names seem too large.

Is there a way, for example, with a regular expression with the sed command or something to rename these files to smaller names. I was thinking of booting in linux, rename the files and boot into windows again afterwards. There is a problem with ~500 filenames, I can't just manually search for those files to change their name.

Sorry if I posted in the wrong place. I presume this is considered as a programming question.

Can't copy files because file names are too long
