When you send an attachment, it has to be encoded to a form that ensures that it will not be damaged by mail systems that can't handle all character codes. This increases its size by about 25% plus some overhead. You initially require 1. space to upload the file so it can be attached. 2. space to save the sent message which will include a copy of the encoded file plus whatever else is in the body and headers of the message. This would set an upper limit on attachment size to about 40% of the free space available to your account. However, successfully sending such a large message also depends on free space in the output email queue and free space in the recipient's mailbox. This can be unpredictable. Perhaps, if you and the intended recipient both have IBM-compatable machines, you might consider cutting your file into pieces, sending one piece at a time, waiting for acknowlegement, and then sending the next piece. You can try using a programme called CARVE.EXE. It can be used to cut large binary files up into pieces small enough to put them on floppy disks. You can then carry them to another computer, save the pieces to the hard disk and use CARVE again to rejoin the pieces. It can cut a file into as many as 999 pieces. Both you and the recipient will need copies of CARVE and UnZip. You will also need Zip. The steps involved would be: 1. Use CARVE to cut up the large file (say BIGFILE.DOC) into 50K pieces (which will be called BIGFILE.001, BIGFILE.002, BIGFILE.003, etc.). 2. Zip each piece into its own zip file (to ensure uploads and downloads are carried out in binary mode) called BF001.ZIP, BF002.ZIP, etc. (This will also save space.) 3. Send BF001.ZIP as an attachment. Wait for confirmation. 4. Repeat step 3 for each piece. With the last piece, include a note that it IS the last piece.) When getting the note that the last piece has arrived, recipient then... 5. Copies all of the BF???.ZIP files to a directory. 6. Unzips all of the files. 7. Uses CARVE to rejoin the pieces into BIGFILE.DOC. 8. Deletes the *.ZIP files and the pieces once BIGFILE.DOC has been checked for correctness.
