UNC names (any path starting with \\?\) do not support slashes. [4] The following examples show MS-DOS/Windows-style paths, with backslashes used to match the most common syntax: A:\Temp\File.txt This path points to a file with the name File.txt, located in the directory Temp, which in turn is located in the root directory of the drive A:.
The path separator is > on Multics, [5] / on Unix-like systems, [6] and \ on MS-DOS 2.0 and later, Windows, and OS/2 systems. An absolute path begins at the root directory; that is, begins with a path separator character, which, at the beginning of a path, represents the root directory. A path consisting only of a path separator character ...
Before the advent of 32-bit operating systems, file names were typically limited to short names (6 to 14 characters in size). Modern operating systems now typically allow much longer filenames (more than 250 characters per pathname element).
On DOS, OS/2, and Windows operating systems, the %PATH% variable is specified as a list of one or more directory names separated by semicolon (;) characters. [5]The Windows system directory (typically C:\WINDOWS\system32) is typically the first directory in the path, followed by many (but not all) of the directories for installed software packages.
Character Name Reason for prohibition / slash: Used as a path name component separator in Unix-like, Windows, and Amiga systems. (For as long as the SwitChar setting is set to /, the DOS COMMAND.COM shell would consume it as a switch character, but DOS and Windows themselves always accept it as a separator on API level.)
Raw strings are particularly useful when a common character needs to be escaped, notably in regular expressions (nested as string literals), where backslash \ is widely used, and in DOS/Windows paths, where backslash is used as a path separator.

For example, a newline character is denoted `n. Most common programming languages use a backslash as the escape character (e.g., \n), but because Windows allows the backslash as a path separator, it is impractical for PowerShell to use backslash for a different purpose. Two backticks produce the ` character itself.
