The Mode page of the Settings dialog affects which files are transferred using ASCII mode.
The file transfer settings made here only affect the SSH Tectia File Transfer GUI, not the SFTP conversion or command-line tools related to file transfer.
By default all files will be transferred in ASCII mode.
By default all files will be transferred in binary mode.
The files using a file extension specified on the ASCII Extensions list will be transferred in ASCII mode. All other files will be transferred in binary mode.
Files using a file extension specified in the ASCII Extensions list will be transferred using ASCII mode.
Click the New icon (at the top right-hand side of the ASCII Extensions list) to add a new file extension to the list. The keyboard shortcut for the New icon is the Ins key.
Note that you can use wildcard characters to specify the file extensions. The ? character matches any 1 character, and the * character matches any 0 or more characters. For example htm* would match both htm and html.
Select a file extension entry from the list and click the Delete icon (at the top right-hand side of the ASCII Extensions list) to remove the extension. The keyboard shortcut for the Delete icon is the Delete key.
