Main Question or Discussion Point

Hi. I try to copy long file names and paths from one source to another but there is a problem. Windows cannot do the operation and gives this error. "File name(s) would be too long for the destination folder"
So how can troubleshoot this problem?

Thank you.

You can shorten the filename and try again, or try a location that has a shorter path.

Yes, I could but I would like to change window's configurations so that I could copy them without changing their names. I do not want to change folder's names.

Thank you.

I don't think that is possible in Windows or any other file system that I know of.

I would recommend what Vanadium 50 suggests. Alternatively you would try kb 2919355 from Microsoft, here https://support.microsoft.com/en-us/kb/2919355. This is a cumulative update for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2. I haven't used it but it claims that one of the issues it fixes, is the one you describe.

Absolutely correct and it is an issue of Windows Explorer itself and not of the NTFS file system.

If the target directory is a subdirectory with a long path, you can define a drive letter that points directly to that target. If the source is also Windows, the destination file names will then be short enough to handle anything in the source path names.

The problem with this is that you are exceeding an internal Windows limit. If we somehow manage to bypass this limit to get the file where you want it, there is absolutely no guarantee that you will be able to use it there. (Or, for that matter, to even delete it, so you risk borking your system) Problems may be subtle - for example, it might be possible to force this file to be created, but the name may be too long for the Registry entry of the application that opens it, rendering it useless.

Try to determine if it's just a few files. I'm on Windows 7, and only have one problem file, a secondary installer update for Visual Studio express, 163 characters long, ...kb3110221.exe with a very long prefix apparently used as parameters.

You should try out Long Path Tool program. I had the same problem, but this solved them all!

Today I tried to make a backup. The windows gave a notification : Too long files names for the source files. It didn't show which files they were so that I could have changed them. Is that program have a special name? How can I get it? Does it determines which paths are too long or it make windows accept long files?

Thank you.

To clarify: the limit in Windows NTFS for the ( name of a file + full device(4):folder name + trailing nul character) = 260. You will also see it referenced as 256 characters with no device name. It is a property of the filesystem. You may also see other numbers which purport to be limits. This is from msdn:
https://msdn.microsoft.com/en-us/library/aa365247(VS.85).aspx

So. If you cd to a directory with a long filename, then create a file in that directory with a long name, you now can get file too long errors when you reference the file from, for example, the c: directory.

Could you use a zipped-up version or CD-image of the files?
Could you use a live linux CD to perform the operation?

Would you please explain what "CD-image of files" here is?

Thank you.
