The Put File button is used to transfer a file from your Macintosh to the host computer. When you press the button you will be prompted for the file you wish to send. Then you will see a dialog box that lets you set the name the file will be given on the other computer and the format it will be stored in. Be sure to pick a name that will be acceptable to the other machine (some systems require file names that are shorter than Macintosh file names and most forbid the use of certain characters). Note that if a file of the name you specify already exists on the other computer it will be overwritten without warning.
The formats you can use when putting a file are Text, Wrapped Text, MacBinary II, Raw Data, BinHex, and AppleSingle. The first two are only available when putting a text file, but the other four are always available. You can specify the default format to use in Preferences (see the Preferences topic). See the help topics for each format for more information.
The progress of the file transfer is shown in the Status panel. You can cancel the transfer by pressing the Stop button.
You can upload multiple files and/or folders by pressing the Put File button with the Option key down, or by choosing Put Folders and Files from the Remote menu. For information see the ╥Put Folders and Files╙ help topic.
If you are running System 7.5 you can drag files and folders from the Finder into transfer windows or directory bookmarks; this can be a more convenient way to start an upload. In that case the default formats will be used.
