The most common way to send a large file via email is to first split the file into multiple parts by using a file archiver utility such as 7-Zip. Once the file has been split, the smaller archives can be sent as email attachments.
- Download and install 7-Zip
Use your Web browser to navigate to the 7-Zip website and left-click on the download option near the top of the homepage. Make sure to select the version that’s appropriate for your operating system; X86 for 32-bit operating systems and X64 for 64-bit operating systems. Once the download is complete, double-click on the setup file, and follow the installation wizard instructions to install the utility.
- Use 7-Zip to split the file
Navigate to the folder containing the file you wish to send, right-click on it, hover over the 7-Zip option, and left-click on the Add to archive option. In the bottom left corner of the compression window, left-click on the drop-down menu under the “Split to volumes, bytes:” heading, and select the size of individual parts. Alternatively, you can type in the desired file size manually. Once the size has been input, left-click on the OK button. This should create multiple split archive files in the same folder as the original file.
- Send the parts as email attachments
Use your Web browser to navigate to the email service of your choice, and select the Compose Mail or New Message option. Click on the attach button, select the Browse option, and find the archive files you wish to send. Once they have been selected, click on OK. Make sure all the files are attached before sending the message.
