5 Free Ways to Transfer Files from C Drive to D Drive

Can I transfer files from C drive to D drive?

In fact, many users have ever been in this dilemma that the C drive is full when there's still much space in the D drive. Usually, when this occurs, you may think about the following two methods:

#1: Move unallocated space to C drive. It requires unallocated space on the right side of the C: drive or you can shrink a drive with plenty of space, and then extend C: drive with the separated out space.

#2: Transfer files from C drive to D drive. It's the simplest way to make room for C drive as long as there is still redundant space on D drive and you know what files can be moved from C drive to another drive (like D, E, F, or G).

Here we will mainly introduce how to transfer files from C drive to D drive or other drives, and you can definitely do so with different methods.

What files can be moved from C drive to D drive?

Since C drive contains the operating system, system files, other applications and their related files, etc, you cannot directly delete files unless you know what files in C drive can be deleted.

Your first thought may be to move all the subfolders under the "User" folder, including Documents, Desktop, Downloads, Favorites, OneDrive, Picture, Music, etc, but not the "Users" folder. Since it contains many information and documents, there will be a conflict if you move it.

And by default, the installation location for new programs is C: drive. If your space is still insufficient after transferring all the user folders, you could consider changing the installation location of the new programs to D: drive.

Meanwhile, there are some files you cannot move, such as Windows, Program Files, and Programs File (x86). The Windows folder stores system files required to start a computer, so you cannot move it. The last two folders are the installation locations of programs. If you move it, the program may stop working or not respond. And some of them only work when installed on the root drive of the hard drive.

Problems you may encounter when transferring files

1. 0x80070057: The parameter is incorrect.

This issue may be caused by corrupted files, network connection problems, or long file paths. You can choose to backup only the subfolder in the "User" folder.

And it's suggested to check both C drive and D drive by navigating to their Properties and selecting Check under the Tools tab.

2. 0x80070780: The file cannot be accessed by the system.

This usually happens when using Cut and Paste. You can choose to use Copy and Paste.

3. The file 'XXX' is too large for the destination file system.

This is due to FAT32 limitation. Files larger than 4GB can NOT be stored on a FAT32 volume. You can either compress the large files or convert FAT32 to NTFS without losing data.
