How can I email a large file to someone that doesn't have Share By Mail? 6. What happens to files deleted by Share By Mail? 1.What's the largest file Share By Mail can send? Share By Mail uses Niwot's Split and Join utilities to break large files into smaller pieces (default 1.2 megabytes each) and put them back together. Niwot's utilities work on Multi-gigabyte files, so there is no limit on the file size Share By Mail can send. 2. How long does it take to send an MP3 file? Our MP3 files range from 2 to 9 megabytes, averaging 4 megabytes. With broadband connections to our email servers and 1 minute intervals between checking the servers we see approximately 1 megabyte per minute. That translates to 4 minutes per MP3 on average. 3. How do you guarantee that all the bits in a transmitted file are correct? We run all the files through our split and join utilities, where an adler32 checksum is generated and checked to ensure all the bits match. 4. What are you doing to make sure nobody else can see what files I am sending or the file contents? If you select "Enable Encryption" any filenames that might be visible in the subject line to a snooper are temporary meaningless file names generated by the operating system, and all of the email body and attachments are encrypted using AES-128 in such a way that only someone using Share By Mail with the same profile and password can decode them. 5. How can I email a large file to someone that doesn't have Share By Mail? Outlook Express has an option in Tools->Accounts->Properties->Advanced called "Break apart messages". You may find this useful. Unfortunately, it will break up all messages from this account to your specified size (regardless of the destination email address) as long as the option is checked. This also has trouble if you overflow the intervening mail servers with too many bytes of email messages. Share By Mail gets around these problems by establishing a flow control email communication between the two ends. 6. What happens to files deleted by Share By Mail? When a file is removed by the user or some other program from a directory monitored by a Peer or Master Profile, indication of that deletion is emailed to the corresponding (Peer or Slave) profile on the far machine. Share By Mail (Peer or Slave) doesn't really delete the files, instead it moves them to C:\Program Files\Niwot\ShareByMail\savedFiles\Profilename\subpath\savedfilename. To create the savedfilename the original name is broken to the left of the last "." in the name and a timestamp _yyyymmddhhmmss in inserted. It is up to the user to clean out the savedFiles directory. You may change where deleted files should be placed by editing (with notepad) Abc*SavedFilesDir= in your sbmconf.txt file.
