How can I send big video/audio files via Email?

Generally, we zip the files to compress and send via email. But when we zip video or audio files, then their size is not reduced to a large extent, hence making it difficult to send via email.
You can try the following steps to compress those files more effectively:

• Change the extension of the file to .txt
• zip the file: Now the file will be compressed to a much larger extent :)
• Send the zipped file via email
• Download the file from email
• Extract the file
• Change the extension of the file from .txt to the original extension
