Windows knows well what disk the file resides on.īelow are my tests in Windows 7, where my findings corroborate those of
I also note that the drive-letter ( C:\) is only included in the text andĭoes not relate to the Windows disk tables (MFT). That's why longer file-names have to be allowed explicitly in theĪnd a program needs to declare its capability to handle long names in its manifest. So that increasing it in the API would cause memory overrun in existing applications. Windows API uses it heavily in its data structures, for example in Is an artifact of a much earlier Windows version.

What are the rules on the lengths of file-names in both Windows 7 and 10.īut first, a small remark: The 260 limit of

I have a simple explanation for the difference : Bad code in Windows 7, The trailing backslash may be a case when we talk about directories, but not files! I cannot understand why this guy talks about a trailing backslash. However, the second quote doesn't make sense to me.
See also: which limits file paths to a paltry 259 characters (sans the terminating null) the current directory to 258 characters (sans a trailing backslash and null) and the path of a new directory to 247 characters (subtract 12 from 259 to leave space for an 8.3 filename). So there are actually 3 limits: 247, 258, and 259.īut why do we have 258 limit for files in the root of the drive and 259 for files in other dirs? For example, C:\foo\aaa.txtĢ58 stands for the max length of the path of a file ( not directory) located in the root of the drive. For example, C:\foo or C:\foo\barĢ59 stands for the max length of the path of a file ( not directory) located not in the root of the drive. Here, 12 stands for 8.3 filename and 1 stands for a NUL terminator. 247, 258, or 259 characters depending on the context).Ģ47 stands for the max length of the path of a directory: 260 - 12 - 1 = 247. Why? C:\abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefgh.txtĬ:\aaa\abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcde.txtĬ:\aaa\bbb\abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_abcdefghijklmnopqrstuvwxyz_a.txt
The maximum length in C:\aaa and C:\aaa\bbb is 259 characters, but the maximum length in C:\ is 258 characters. Then I do the same test in C:\aaa and C:\aaa\bbb.įor some reason, the results are different. (Actually, I use copy-and-paste, of course. I open the manager, create the file abc.txt in C:\, and then add letters to abc as long as the file manager allows it. I try to understand what is the maximum valid length of the path a file.įor this, I use the default Windows file manager, on Windows 7, and the following PowerShell script: Get-ChildItem | Select Name, FullName, Length" E= | Format-List
