Remarks

Note

The current element is not modified.

Time-out

By default, all the FTP functions fail if the FTP server does not respond within 20 seconds. This time-out can be modified by FTPConnect when connecting to the FTP server.

Rights of users

Only a user who has read rights on the FTP server can get information about the files or the directories found on an FTP server. In most cases, the read rights are granted to the "anonymous" users.

Relative and absolute path

The notions of relative path and absolute path are very important in an FTP application.
  • A path starting with a slash is considered as being an absolute path: it is the path in relation to the root of the FTP server (parameter specific to the server).
    ex: /ad/user/JULIA
  • A path not starting with a slash is considered as being a relative path, which means a path given in relation to the current directory. This current directory can be returned or modified by FTPCurrentDir.
When connecting to an FTP site, the initial directory (the "home directory" of the user) is not necessarily found at the root of the FTP server. Therefore, we recommend that you use relative paths.
