How to Use Windows Script to Check Disk Space and Send Email Alerts
Setting up Windows script to check disk space can effectively monitor the state of the hard disk space and prevent low disk space problems.
Now you can configure the hard disk monitor to check the hard disk space and send email alerts to you when the hard disk is about to run out of space.
You can create a script as follows to check the hard disk and save it to your home directory:
#!/bin/bash
CURRENT=$(df / | grep / | awk '{ print $5}' | sed 's/%//g')
THRESHOLD=90
if [ "$CURRENT" -gt "$THRESHOLD" ] ; then
mail -s 'Disk Space Alert' mailid@domainname.com << EOF
Your root partition remaining free space is critically low. Used: $CURRENT%
EOF
fi
Then you can add this command line at at the end of /etc/crontab file:
@daily ~/sample.sh
And you need to change the email in to your email address. The threshold of the used hard disk space is set as 90% here, which means when the used hard disk space is up to 90%, the system will send a low disk space to your email.
What to Do when Hard Disk Send You Low Disk Space Alert
When you hard disk send low disk space alert to you, it means your system drive space has been used more than 90%. Then you will need to manage the hard disk space as soon as possible. Here are some solutions for you.

First delete those useless files on the system drive to spare some space on the system drive. You can delete the temp files and uninstall some useless programs.

You can use system tools to extend the C drive first, you can try “My Computer”>”Manage”>”Disk
Management”, right click the C drive, choose “Extend Volume”.
You can also use diskpart command prompt to extend C drive.
1. Press “Win+R”, type “CMD”.
2. Type “diskpart” in the command window.
3. Type “list volume” .
4. Type “select volume X (X is the drive letter of your C drive.) to go
5. Type “extend size=10240 (size stands for the capacity you will extend by and the unit is MB) and Enter
But these two solutions are only for the situation when there are unallocated space adjacent to the C drive.
