3.7 FILE NAMING CONVENTION All the file systems follow the same general naming conventions for an individual file: a base file name and an optional extension, separated by a period. However, each file system may have own naming convention. Some of the basic rules followed while naming file sin Windows are listed below:

→ Use a period to separate the base file name from the extension in the name of a directory or file.

→ Use a backslash (\) to separate the components of a path.

→ Use a backslash as required as part of volume names, for example, the "C:\" in "C:\path\file".

→ Do not assume case sensitivity. For example, WINDOWS and windows should be treated equal.

→ Use any character in the current code page for a name, including Unicode characters and characters in the extended character set (128–255) except for the following reserved characters:

•  < (less than)
•  > (greater than)
•  : (colon)
•  " (double quote)
•  / (forward slash)
•  \ (backslash)
•  | (vertical bar or pipe)
•  ? (question mark)
•  * (asterisk)
