4 ways to undo disk cleanup and recover lost files

How to undo disk cleanup and recover lost files in Windows? Before that we have to understand the principle of data storage, data is stored in sectors on the disk, if you simply delete or clean the data, in fact, the sectors of data storage are not cleaned up, they are cleaned up only by the name of the file representing the data. All that is cleaned up is the name of the file that represents the data. So, if you want to undo the disk cleanup and recover your important files or data, there are three ways:

➡️Way1: Reinstall or transfer back

In order to clear up the disk space, you may have uninstalled some applications or programs that come with the system, but the uninstallation or transfer of these programs may affect the running speed of your computer, so if you want to restore the normal operation of your computer, you just need to re-download the programs or transfer the necessary programs back to ensure the running efficiency of your computer.
