EFT Server, the Web Transfer Client, and the HTML Listing and Upload Form follow the standard Windows naming conventions, with a few exceptions (such as no support for 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. (Unicode characters are not supported, but certain UTF-8 characters are supported.)
