File-Naming Conventions

EFT follows the standard Windows naming conventions, with a few exceptions. (Please refer to Unicode File Transfers and Unicode Exceptions for details of using Unicode characters.)

For example:

  • You can name files using almost any character for a name, except for the following reserved characters:
    < > : " / \ | ? * %

  • The maximum length for a path is 255 characters. This limitation includes the drive letter, colon, backslash, directories, subdirectories, filename, and extension. If the relative path is too long, a warning message appears.

  • Characters that are valid for naming files, folders, or shortcuts include any combination of letters (A-Z) and numbers (0-9), plus the following special characters.
