Using DMTS High Speed or dialup service, you can send or receive a single file attachment with no limit.
It is physically possible to send someone a larger file attachment. However, before sending someone a large file you should first ask them if they can handle them. The intended recipient may be on a dial-up service where a large file attachment may cause their service to appear to have stalled while trying to download the large file.
To transfer large files, it would be in the best interest of both the sender and the intended recipient if the file was to be compressed using a program such as 7-Zip (www.7-zip.org). In order to open it, the recipient must have the ability to un-compress this file. There is an open-source program called 7-Zip available at www.7-zip.org.
Please be aware that DMTS Internet Services does not offer product support for 7-Zip. 7-Zipis mentioned only as a possible solution to problems caused by large email attachments. This does not represent an endorsement of 7-Zip products by DMTS.
