Transfer / Client / start_directory_listing

start_directory_listing#

Transfer.Client.start_directory_listing(**kwargs)#

Retrieves a list of the contents of a directory from a remote SFTP server. You specify the connector ID, the output path, and the remote directory path. You can also specify the optional MaxItems value to control the maximum number of items that are listed from the remote directory. This API returns a list of all files and directories in the remote directory (up to the maximum value), but does not return files or folders in sub-directories. That is, it only returns a list of files and directories one-level deep.

After you receive the listing file, you can provide the files that you want to transfer to the RetrieveFilePaths parameter of the StartFileTransfer API call.

The naming convention for the output file is connector-ID-listing-ID.json. The output file contains the following information:

  • filePath: the complete path of a remote file, relative to the directory of the listing request for your SFTP connector on the remote server.

  • modifiedTimestamp: the last time the file was modified, in UTC time format. This field is optional. If the remote file attributes don’t contain a timestamp, it is omitted from the file listing.

  • size: the size of the file, in bytes. This field is optional. If the remote file attributes don’t contain a file size, it is omitted from the file listing.

  • path: the complete path of a remote directory, relative to the directory of the listing request for your SFTP connector on the remote server.

  • truncated: a flag indicating whether the list output contains all of the items contained in the remote directory or not. If your Truncated output value is true, you can increase the value provided in the optional max-items input attribute to be able to list more items (up to the maximum allowed list size of 10,000 items).
