How to increase disk space for linux operating systems installed on virtual machines

Today, the worker wants to add a hard disk to the new linux operating system on the virtual machine. In fact, it is not his existing virtual machine hard disk space is insufficient, however, when he dragged a file from windows to linux, he found that the space was insufficient. What is the situation? Why is it insufficient? In fact, he found that when dragging files from windows to linux, he did not drag the files directly to the directory he specified, but copied the files to the/tmp directory first, then copy/tmp to the specified directory. Currently, the/tmp space is insufficient, and the drag-and-drop operation fails. Later, he found me and thought about it. the/tmp directory www.2cto.com sudo cp/tmp is backed up. /tmp. old 2. delete the/tmp directory and create a new soft connection sudo rm/tmp sudo ln-s user home directory/tmp. After step 2, our/tmp still exists, however, when data is stored in the/tmp directory, it is not stored in the/tmp directory, but stored in the user's main directory. Because the user's main directory has a large space, it solves the problem of insufficient/tmp space and finally achieves the desired result. If you want to solve the problem, you can always solve it.
