entirety.<\/li>\n\n\n\n<li>After that, the user needs to navigate to their data path.<\/li>\n\n\n\n<li>Then the user needs to paste the folder that they had copied in the step above.<\/li>\n\n\n\n<li>Then need to verify that they can open their company without any issues.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\"

If that is the case, then the user must go to the location where that file is stored on the user\u2019s workstation, and then they must right-click on the file. Right-clicking on the file will open a menu, from which the user is supposed to click \u2018Properties\u2019.<\/li>\n\n\n\n<li>There will be a checkbox with the label \u2018Read-Only\u2019 next to it.
