Windows ntfs max path length

This prefix determines the namespace the path is using, and additionally what special characters are used in which position within the path, including the last character. Each component of a path will also be constrained by the maximum length specified for a particular file system. In general, these rules fall into two categories: short and long. Note that directory names are stored by the file system as a special type of file, but naming rules for files also apply to directory names.

To summarize, a path is simply the string representation of the hierarchy between all of the directories that exist for a particular file or directory name. For Windows API functions that manipulate files, file names can often be relative to the current directory, while some APIs require a fully qualified path.

A file name is relative to the current directory if it does not begin with one of the following:. If a file name begins with only a disk designator but not the backslash after the colon, it is interpreted as a relative path to the current directory on the drive with the specified letter.

Note that the current directory may or may not be the root directory depending on what it was set to during the most recent "change directory" operation on that disk. Examples of this format are as follows:. A path is also said to be relative if it contains "double-dots"; that is, two periods together in one component of the path.

This special specifier is used to denote the directory above the current directory, otherwise known as the "parent directory". Relative paths can combine both example types, for example "C This is useful because, although the system keeps track of the current drive along with the current directory of that drive, it also keeps track of the current directories in each of the different drive letters if your system has more than one , regardless of which drive designator is set as the current drive.

In later versions of Windows, changing a registry key or using the Group Policy tool is required to remove the limit. See Maximum Path Length Limitation for full details. There are two main categories of namespace conventions used in the Windows APIs, commonly referred to as NT namespaces and the Win32 namespaces. The NT namespace was designed to be the lowest level namespace on which other subsystems and namespaces could exist, including the Win32 subsystem and, by extension, the Win32 namespaces.

Early versions of Windows also defined several predefined, or reserved, names for certain special devices such as communications serial and parallel ports and the default display console as part of what is now called the NT device namespace, and are still supported in current versions of Windows for backward compatibility.

The Win32 namespace prefixing and conventions are summarized in this section and the following section, with descriptions of how they are used. Note that these examples are intended for use with the Windows API functions and do not all necessarily work with Windows shell applications such as Windows Explorer.

For this reason there is a wider range of possible paths than is usually available from Windows shell applications, and Windows applications that take advantage of this can be developed using these namespace conventions.

For more information about the normal maximum path limitation, see the previous section Maximum Path Length Limitation. I have to manually rename every folder to a single character to finally delete the whole stuff.

Did I oversee something or do I have to manually install anything via Server dashboard. Length Hi Jan! Thanks for the explanation. I have these issues with: Error: File or path name s length must not exceed characters. I tried following your explanation but stumbled at two points: — domain controller : I guess this is a server that can be used to get all servers aligned, alright?

But as far as I can see, the issue remains stable long pathes are not allowed. From the Policy help text:. Thanks for the answer! I thought that you were saying that this would work on a Windows Server domain controller. I have done this, buts its not working. Tryed on windows server , local gpo and domaine gpo.

Same result. I have go all rettings in regedit and all settings is enabled.
