If you're trying to send large files to someone, email usually won't work. Most email service providers have limited file sizes. You should therefore look for other options to be able to send large files. If you have a Google account, you can use the free Google Drive storage to upload files and then share a file of almost any type or format.
Steps
Part 1 of 3: Uploading a file

Step #1. Sign in to the Google Drive website
Each Google account comes with 15 GB of free storage on Google Drive. If you use Gmail, you can simply use your Gmail login information to access your Drive account. Sign in to drive.google.com.
If you're using a mobile device, the Google Drive app is available for Android and iOS. You can use this app to upload files from your mobile device to your Drive storage

Step 2. Click the 'New' button and select 'Upload files'
This will open the file browser where you can search your computer for the file you want to upload to Google Drive. You can also drag and drop a file into the Google Drive window to instantly upload the file.
Google Drive supports files up to 5 TB in size (provided you really have that much storage space available)

Step 3. Wait for the file to be uploaded
Uploading large files can take quite some time, especially if you have a slower internet connection. You can follow the upload progress in the bar in the lower right corner of the Drive window.
The upload will be canceled if you close the window while the file is still uploading. You must keep the Google Drive window open until the file is uploaded
Part 2 of 3: Sharing the file (desktop)

Step #1. Understand how files on Google Drive are shared
There are essentially two different ways you can share a file you've uploaded to your Drive: you can share it with specific Drive users or create a link that anyone can use to access the file.

Step 2. Right click on the file and select 'Share'
This opens the file sharing menu.

Step 3. Enter the contacts in the "People" field to share with specific users
You can type in the names of your Google contacts or add email addresses. Email invitations will be sent to each person you add. If the recipient is not a Google Drive user, he or she will be invited to create a free account.
Change the access rights by clicking the 'Editor' button. You can change this to 'Responder' or 'Reader'. To download the file, the user must have permission as 'Editor' or 'Reader'

Step 4. Click the 'Get Link' button to create a link that you can send to anyone
If you're sharing with someone who doesn't use Google Drive or want to share a file with strangers, you'll need to create a shareable link. Anyone can then see and upload the file from your Google Drive account with this link. Copy and paste the link into an email or chat and send it to the desired recipients.
- As with the other sharing method, you can adjust the access permissions for those who access your file through the shared link.
- Creating a link is the best method if you are not sure if the recipient is using Google Drive. Anyone can download the file with this without having to create an account.

Step 5. Download the file
You may need to tell the recipient how to download the file, as just clicking the link to open it won't automatically download it.
To download a file open in Google Drive, click or tap the "Download" button at the top of the window. If the file opens in Google Docs or Google Sheets, it must be downloaded from the file menu
Part 3 of 3: Sharing the file (mobile)

Step #1. Understand how files on Google Drive are shared
There are essentially two different ways you can share a file you've uploaded to your Drive: you can share it with specific Drive users or create a link that anyone can use to access the file.

Step 2. Tap the ⓘ next to the name of the file you want to share
This will open the details of the file.

Step 3. Tap "Add People" to invite people to download the file
You can type in the names of your Google contacts or add email addresses. Email invitations will be sent to each person you add. If the recipient is not a Google Drive user, he or she will be invited to create a free account.

Step 4. Tap "Share Link" to send a link to the file
This will open the share menu on your device so you can add the link to a new email, SMS, or other sharing method installed on your device. You can also choose to copy the link to your device's clipboard so that you can manually paste it somewhere.

Step 5. Adjust the access permissions in the 'Show who has access' section
If link sharing is enabled for the file, you can set the permissions for users who visit the link. If you've shared the file with certain people, you can set each of their access rights individually.

Step 6. Download the file
You may need to tell the recipient how to download the file, as just clicking the link to open it won't automatically download it.
