FTPFileExist (Function) In french: FTPFichierExiste Checks the existence of a file on an FTP server (File Transfer Protocol). Info(FTPFileExist(nIDSession, "/Document/Fichier.txt"))
Syntax
<Result> = FTPFileExist(<Connection ID> , <File name>)
<Result>: Boolean - True if the file exists,
- False otherwise. To get more details on the error, use ErrorInfo with the errMessage constant.
<Connection ID>: Integer Connection identifier, returned by FTPConnect. <File name>: Character string Name and full (or relative) path of the file be accessed. The different path sections are separated by "slashes" ("/"). Remarks Special case The current element is not modified. Timeout By default, all the FTP functions fail if the FTP server does not respond within 20 seconds. This timeout can be modified with 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 beginning with a slash is considered an absolute path: this is the path relative to the FTP server root (server-specific parameter).
ex: /pub/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 "base directory" of the user) is not necessarily found at the root of the FTP server. Therefore, we recommend that you use relative paths.
