What is .xtm file?
These are the data files created by Xtremsplit, a utility that splits large files into several smaller files and then rebuilds them. These are useful for transferring large amounts of data in over the web or email attachments.
The recipient of an XTM file may reconstruct the original file irrespective of the sender. The receiver of the file does not need the Xtremsplit software in order to reconstruct the XTM files once they are received.
