On Library Creator, an error (Cannot open a file. See the processing dialog for the file name. Skip the file or abort creating the library? Error Code: E-02) is displayed and I cannot register a file in my library.

It is possible that the file pathname (folder name + filename) is too long. Pathnames that exceed 256 characters cannot be registered in the library. Shorten the filename or migrate the file to a higher-rank folder and then try shortening the pathname (folder name + filename).

*With Mac OS, if the pathname is too long, it will not be able to be displayed normally. Because a file of this type will be treated as if it doesn’t exist, no error message will display.
