We begin with the absolute limit imposed by Windows. The operating system API puts a limit (called MAX_PATH) of 260 characters for the complete name with the path included. This number is often quoted. However, actual limits are smaller because of various other restrictions. For example, all names have to have a null terminator at the end. Normally only the computer sees this end marker but it counts as a character so there are really only 259 characters available. (Forgetting to count the null terminator is a common mistake.) Another three characters are used by the drive or volume designation (e.g., C:\). Thus, the limit for naming all the folders and subfolders plus the file is reduced to 256 characters. However, no individual file or folder can have a name longer than 255 characters. This includes spaces and back slashes used as separators.

Max password length in Windows 10, Server 2003 & other modern operating systems

Internally, Windows represents passwords in 256-character UNICODE strings. The logon dialog is limited to 127 characters, however. Therefore, the longest password that can be used to log on interactively to a computer running Windows is 127 characters. Theoretically, programs such as services can use longer passwords, but they must be set programmatically because the password change dialog will not allow a password longer than 127 characters, says an article about Passwords FAQ on TechNet.

Times when you might see this kind of issue:

http://tech-faq.com/cannot-copy-the...

Usually when you are backing up something. :-)

You think, I'll just leave it to get on with it, it will take it hours..

You come back hours later, and find its copied 5% before it hit this wall..

@Root Ah, I see you like DVDs.

@filthyranter I like controversy because it illustrates people being horribly wrong and letting emotion or greed surpass or supplant their reasoning.
