====== Session.GetFiles Method ====== ====== Session.GetFiles Method ======
-Downloads files. +[[task_download|Downloads]] one or more files from remote directory to local directory. 
 + 
 +You can have WinSCP [[guide_automation#generating|generate a code template]] for ''Session.GetFiles'' for you. 
 + 
 +The method is quite powerful, but due to a wide range of it uses, its syntax can be cumbersome initially. For specific tasks, consider using convenient alternatives: [[library_session_getfilestodirectory|''Session.GetFilesToDirectory'']] and [[library_session_getfiletodirectory|''Session.GetFileToDirectory'']].

^ Name ^ Description ^ ^ Name ^ Description ^
-| string remotePath | Full path to remote file to download. Filename in the path can be replaced with [[file_mask|wildcard]] to select multiple files. When file name is omited (path ends with slash), all files and subdirectories in the remote directory are downloaded. | +| string ==remotePath== | Full path to remote directory followed by slash and [[library_wildcard|wildcard]] to select files or subdirectories to download. To download all files in a directory, use mask ''*''. ·| 
-| string localPath | Full path to download the file to. When downloading multiple files, the filename in the path should be replaced with [[operation_mask|operation mask]] or omited (path ends with backslash). | +| string ==localPath== | Full path to download the file to. When downloading multiple files, the filename in the path should be replaced with [[operation_mask|operation mask]] or omitted (path ends with backslash). | 
-| bool remove | When set to ''true'', deletes source remote file(s) after transfer. Defaults to ''false''. |+| bool ==remove== | When set to ''true'', deletes source remote file(s) after a successful transfer. Defaults to ''false''. |
| [[library_transferoptions|TransferOptions]] options | Transfer options. Defaults to ''null'', what is equivalent to ''new TransferOptions()''. | | [[library_transferoptions|TransferOptions]] options | Transfer options. Defaults to ''null'', what is equivalent to ''new TransferOptions()''. |

-~~NOTOC~~+===== Remarks ===== 
 +Event ''[[library_session_filetransferred|Session.FileTransferred]]'' is raised for every downloaded file. Also raises [[library_session_filetransferprogress|''Session.FileTransferProgress'']] throughout the transfer. 
 + 
 +The download aborts on the first error. See how to [[library_example_recursive_download_custom_error_handling|implement recursive directory tree download with custom error handling]].
