Magento2.3.1 : No.of files increased

https://www.depoto.com/ When I tried to open my website, I am getting the error that There has been an error processing your request

Then I checked in system.log.

The error is Disk quota exceeded

The no.of files count make doubled to the original files count when i deploy the content.

Note: I have a single Magento installed website only.

Why that much of files existed in Magento?
