There is a limitation on the size of message you can send overthe mail system. If, for example, you want to includea large file (above 32KB) in a message,the recipient may find that part of the file has been lost(truncated) during the transfer, although no error message will appear.You can find out the size of a file by entering:
!l filename

See the discussion on working with files and directoriesin the Operating System User's Guide or thels(C)manual pagefor more information about the l command.

I was able to pack hundred of photos into one single 800 mB file, then downloaded by family members. More accurately, QQ.com provides free file transfer service. The files are presented as links for the recipients to download, so it does not require the recipients to have a qq mailbox for the same capacity. The total mailbox is 2GB. JUMBOmail allows you to send and share XL files up to 20GB easily and securely. It only takes a few clicks to send your photos, videos, music, documents, or any type of BIG files you will choose to send. Just select the files or folder you wish to share and we will do the heavy lifting quickly and efficiently.

One solution is to compress and encodea file before including it in your message.Compressing a file reduces its size by about 50%; encoding the file increasesthe size of the compressed file by about 30%, so youend up with a compressed and encoded file that is about twothirds the size of the original. If this still leaves a filethat is too large to send, you should, if possible, split the file intosmaller files before compressing and encoding them.

The reason why you should encode a compressed file before you send itis because compressed files may include characters that are notrecognizable to SCO Shell Mail.Although you may be ableto send the compressed file, it may well be truncated orincorrectly transmitted by SCO Shell Mail.

If you are a SCO Shell Mail user, the encoding of a file is doneautomatically for you when you attach the file to a message. So,if you want to send a compressed file to someone, you should alwaysattach it to the message instead of including it in the message.If, for some reason, you need to include the file in a message,you should follow the procedure given in``Including information from other applications in a message'.

Because you can only compress a file from thecommand line(that is, there is no SCO Shell command for doing this),enter the following UNIX system commandsfrom within SCO Shell using an exclamation mark.

Assume that you have a file called myfile that youwant to send via mail to one of your colleagues.To compress the file, type:
!compress -c myfile > myfile.Z

The compressed file is named myfile.Z;attach this file to the mail message to be sent, but donot edit its contents.

Qq File Transfer

The recipient of your mail message can recover a copy ofthe original file by saving the attachment to afile (here named mmsg), and entering the following command:
!uudecode -s mmsg > myfile
