    (*) This number includes all the files managed, in other words: active files, archive files, data exchange files as well as deleted files.

    (**) If a special character is detected (non UTF-8), the name will be encoded with %MNGA182 then HEX of the source name and this will reduce the the size of the name (the special character will take 4 characters space).

    (***) This length matches the PATH_MAX that is supported by the operating system. The Unicode representation of a character can occupy several bytes, so the maximum number of characters that comprises a path and file name can vary. The actual limitations are :

    1. the number of bytes in the path and file components, which might correspond to an equal number of characters.
    2. which is superseded by maximum of 21845 characters
