+	Short:     "copy one or a list of files to a filer folder",
+	Long: `copy one or a list of files, or batch copy one whole folder recursively, to a filer folder
+
+  It can copy one or a list of files or folders.
+
+  If copying a whole folder recursively:
+  All files under the folder and subfolders will be copyed.
+  Optional parameter "-include" allows you to specify the file name patterns.
+
+  If any file has a ".gz" extension, the content are considered gzipped already, and will be stored as is.
+  This can save volume server's gzipped processing and allow customizable gzip compression level.
+  The file name will strip out ".gz" and stored. For example, "jquery.js.gz" will be stored as "jquery.js".
+
+  If "maxMB" is set to a positive number, files larger than it would be split into chunks and copyed separatedly.
+  The list of file ids of those chunks would be stored in an additional chunk, and this additional chunk's file id would be returned.
