File System Limitations
4
The following list summarizes a number of file system limitations.
File Names and Entries
4
• The maximum file name length is 97 characters, including the file
name extension.
• This space character is supported within a file name provided the file
name is delimited by double quotes (for example, “filename with
space”). Double quotes are not allowed within a file name.
• The maximum number of entries (files and folders) depends upon the
eMAM size and the compression rate of the file system and MXF
data.
FTP Server Encoding Scheme Limitations
4
• The FTP server accepts all bytes except NULL (0x00), LF (0x0A),
CR (0x0D), “ (0x22), / (0x2F), and \ (0x5C).
• The FTP server is fully compatible with any NVT-ASCII character
encoding scheme. This includes ASCII, ISO 8859-x suite (Latin-1 to 9,
Cyrillic, Arabic, Greek, Hebrew, Thai), Japanese JISX0201, JISX0208,
JISX 0212, EUC, S-JIS, and UTF-8.
• UTF16, UCS-2, UTF32, and UCS-4 are not supported because they fill
unused bytes with the NULL value.
• The total number of bytes to code a character of a filename depends
on the encoding character set. For example, UTF-8 characters are
triple bytes, EUC-JP characters are double bytes, and US-ASCII
characters are single bytes. Therefore, the maximum number of
characters per filename depends on its character encoding.
FTP Server and FTP Client Character Set Handling
4
• Java encodes everything in UTF16. The built-in FTP client has no
specific function to convert the S-JIS character set to EUC.
• When using the FTP client, any connection to a FTP server requires a
name, IP address, login, password, port, and an encoding scheme
(character set). These parameters are entered via text areas and
combo boxes located on the
Configuration
tab of the FTP client.
