Transferring Files with MTWeb

The Web client and/or Ad hoc contacts can use the MassTransit Web Assistant plug-in or the HTTP feature of MassTransit to transfer files.

Only the MassTransit plug-in can use the advanced communication protocols of MassTransit - TCP/IP, TCP/IP Secure, and UDT. They provide the ability to modify the transfer packets and buffer sizes in order to increase the transfer speed. In addition, the MassTransit Assistant plug-in allows transferring huge file volumes. In HTTP mode on the other hand, you can only transmit up to 2GB of files in a single transfer but your MTWeb users will be able to send and receive files without installing anything on their machines.

Ad hoc delivery works in both transfer modes plug-in and HTTP. They also provide secure file transfers when configured.

Using the MassTransit plug-in, you can drag and drop files for uploading, and Unicode support for the file names is implemented.

Below you can find information about the differences between the two transfer methods.

MassTransit Web Assistant Plug-in

• Advanced communication protocols (TCP/IP, TCP/IP Secure, UDT)
• Ad hoc delivery
• Drag&drop for uploading files
• Unicode support
• Secure file transfers
• Large file transfers (over 2 GB or longer than 1 hour)

HTTP

• Ad hoc delivery
• Secure file transfers

Note: Please note that the maximum allowable file size you can transfer in a single file transfer in HTTP mode is 2GB. This maximum size can be set by the MassTransit Server administrator and may be less than 2GB.

The MassTransit Assistant plug-in does not have such a limitation.

MassTransit Unicode Support

MassTransit 6.0.2 and later support transfers of files and folders with Unicode characters in TCP/IP, TCP/IP Secure, and UDT file transfers. By default, MassTransit will queue and transfer files and folders with high Unicode (>0xFF) successfully across the MassTransit protocol (TCP/IP, TCP/IP Secure, and UDT connections).

Note: Note that Unicode is not fully supported for web client HTTP transfers, hot folder transfers, FTP transfers, or with AppleScript. If you have Unicode support enabled and use Unicode filenames with these features, you may encounter file not found errors or munged filenames.

Note: Having Unicode support enabled on your server will still fail to transfer Unicode characters when connecting to legacy contacts or contacts with Unicode support disabled.

There are a number of limitations to Unicode support:

• FTP and Hot Folder communication methods do not fully support Unicode characters. Most Unicode characters will be munged when transferred with these communication methods.
• Unicode is not supported for web client HTTP transfers. Both Windows and Mac web clients will present an error if a user attempts to transfer files or folders containing Unicode characters. This limitation will be removed in a future release.
• Unicode characters in folder names will be replaced with dashes in web client downloads. This limitation will be removed in a future release.
• Unicode is not fully supported in the MassTransit user interface or email notifications. Unicode characters may not be properly displayed in the MassTransit Log, Files window, and email notifications containing file lists.
• MassTransit’s AppleScript interface does not support retrieval of Unicode characters. If a script retrieves a Unicode file name or folder name via the AppleScript interface, the file name will not be correct. This may impact the success of purging and workflow scripts processing files and folders with Unicode characters in the names.
• Programmatic submission of files containing Unicode characters (via COM, AppleScript, or SOAP) is not supported at this time.
• Only Unicode characters up to 0xFFFF are supported.
