File System
The files system is a fixed-size storage area with a hierarchical directory structure.
Any data, user or application can be stored in files within the file system. Files can
be grouped in directories for readability.
The file system features two security levels. Depending on security level, different
users can have access to different files and directories. The file system is accessi-
ble via FTP, Telnet, and HTTP.
File System Conventions
Case Sensitivity
The file system is case sensitive. This means that the file ‘pyramid.txt’ is not iden-
tical to the file ‘Pyramid.TXT’.
Filename / Pathname length
Filenames can be a maximum of 48 characters long. Pathnames can be 256 char-
acters in total, filename included.
File Size
The file size is not restricted. Naturally, a file cannot be larger than the available
space, see below.
Free space
There is approximately 1.4MB available for user files.
