  • Move files from C drive to D drive.

This is the easiest way to free up space on C drive, as long as there is still extra space on D drive.
Here we will mainly introduce how to transfer files from C drive to D drive, and you can surely use the most convenient method – using free sync software AOMEI Backupper Standard. Next we’ll start by looking at what files we can transfer.

Which Files are Transferable from the C Drive to the D Drive?

Given that the C drive encompasses the operating system, system files, and various applications along with their associated files, it is important to exercise caution when deleting files directly unless you are certain about which files in the C drive can be safely removed.

Your initial inclination might be to relocate all the subfolders within the “User” folder, such as Documents, Desktop, Downloads, Favorites, OneDrive, Pictures, Music, and more, excluding the “Users” folder. However, it is essential to note that the “Users” folder contains significant information and documents, and moving it may lead to conflicts.

Moreover, it is worth noting that new programs are typically installed in the default location on the C: drive. If you encounter insufficient space even after transferring all the user folders, you could consider altering the installation location for new programs to the D: drive.

Nevertheless, certain files cannot be moved, including the Windows folder, Program Files, and Program Files (x86). The Windows folder houses vital system files necessary for computer startup, making it unfeasible to relocate. The latter two folders serve as installation directories for programs, and moving them may result in program malfunction or unresponsiveness. Moreover, some programs exclusively function when installed on the root drive of the hard drive.
