Backslash vs. Forward Slash

The symbol (\) is called a backslash, while (/) is called a forward slash, which is also known as a virgule, a stroke or even an oblique dash. Thus there are two types of slashes in the English language: a backslash (\) and a forward slash (/).

The backslash (\) is a typographical mark used merely for computer coding and file names. It is not a form of punctuation mark in English. We often use the backslash to separate computer folder names, especially in Windows systems.

The backslash (\) Examples:

  • C:\Program Files
  • D:\OFFICE\OFFICE 2010

The forward slash (/), often simply referred to as a slash (which is also known as a stroke, a virgule, or even an oblique dash), is a punctuation mark used in English. The slash can be used to separate lines in a song or poem when they are written in a continuous line. This punctuation mark is also used in place of the word or. It can also be used to show two contradictory notions.
