These are the sample data files for the Total WordPress Theme. Please purchase the theme first before using the sample data, if you are using an illegal copy of the theme you will most likely encounter many errors while importing the files.
These files are here for dev reasons and manual importing. You should be using the theme importer to import sample data, not these files. Please view the documentation here: https://wpexplorer-themes.com/total/docs/importing-sample-data/
The MASSIVE sample data from the base demo - https://total.wpexplorer.com/base/ Could take a long time to upload and some servers may not be able to handle it. It would be recommended to instead import the Base Lite demo.
