Help, the Robocopy command doesn’t work!

Recently, I found my C drive was almost full and so I needed to free up some space. I thought of Robocopy and tried to use the command lines to move some apps from the C drive to the D drive. However, when I tried moving Firefox from Program Files to the D drive with the command lines, I was prompted that the parameter was invalid.

Why Robocopy all files and folders to another drive?

Robocopy, short for “Robust File Copy”, is a command-line directory and file replication command for Microsoft Windows. Robocopy functionally replaces Xcopy with more options and features. With Robocopy, users can not only move files including apps and programs within one drive but also, they can transfer those files between 2 drives like C and D.

Over time, the C drive, which is also called the system drive, will run out of storage. When this happens, your computer’s performance will be affected very much. For example, when the C drive is low on space, the system speed can become dramatically slow and glitches like frequent crashes may also occur. In this case, Robocopy is a good choice to free up some C drive space by moving some software and apps to another drive like D, E, and F from it.

How to use Robocopy to move files between 2 drives?

As we see above, C drive full can cause many problems and we should use tools like Robocopy to free up some space by transferring some files to another location. Here, I’ll introduce 2 set of command lines of Robocopy to help transfer files between drives. Below, I’ll move Firefox for example.

Option 1.

If you’re moving all NTFS ACLs, file owners, subfolders and all file attributes, you should add “/E” to include all empty subfolders and “/COPYALL” to catch the rest. Here is the example for Robocopy to copy all files and folders of Firefox from C to D.

robocopy C:\Program Files\Mozilla Firefox D:\sample /E /COPYALL

Option 2.

Moving files transfers files from one location to another similar to copying. The only difference with this operation is that the source file will be deleted after the copy. Follow the command lines below to get it done.

Robocopy C:\Program Files\Mozilla Firefox D:\sample /MOVE

An alternative to Robocopy for file transfer

Robocopy is a convenient inbuilt utility of Windows series with many useful features to help copy files. This is great. However, many novices respond Robocopy is too complicated and it’s hard to find an explicit tutorial on the internet. Moreover, some people claim that when they try copying files to another drive in the 2 methods mentioned above, they’re prompted with the notification that the parameter is invalid. So, what now?

Luckily, in this case, AOMEI Partition Assistant Professional may help you out.
