Question:
Hi, I recently noticed my drive C becomes lesser in free memory. Then I got a low disk space warning saying there is no free space on C, therefore I deleted a couple of videos I had in fraps folder. Then there were around 300mb free. Now all of a sudden it has decreased to 40Mb free. I did not install any program. I also scanned with Avast, but there were no harmed files.

Is this a common issue? Of course, this is quite possible. Hard drive is a data storage media, and you are storing more and more data and applications in it. As time goes by, the free space of hard drive may run out, and you will get low disk space warning when the free space is less than 200MB. Especially for drive C. When drive C is full, the computer will run slower and slower which can influence your work and life from time to time.
 
So, what can you do when your drive C is almost full? Extending partition is an effective way. But when there is no available space for extending your drive C, you have to buy a new hard drive to replace the old small one. And then, you should install Windows operating system to the new hard drive. Generally speaking, this installation process is really an annoy experience, which will take a long time and after the installation, you must reinstall all the needed applications to your computer. So, is there any migrating OS to hard drive freeware available? Of course, there is. Technicians design pieces of partition software for your use.
 
Actually, there are good and bad software all over the world today. To make your information safe, we recommend you to apply professional software. And MiniTool Partition Wizard is a good choice.

How to Migrate OS to Hard Drive

 
Step 1. You should purchase and install MiniTool Partition Wizard Server Edition to your computer. Open and launch it to get its main interface. Then click “Migrate OS to SSD/HD Wizard” from the left tool bar.

 
Step 2. Select destination disk from this interface and press “Next” to get the next page.

 
Tips: (1) The destination disk should have enough space to store data of the source disk.
(2) The content of the destination disk will be deleted once the operation of “Migrate OS to SSD/HD Wizard” comes into force. So, if there are important data in the destination disk, users should make a backup first.

 
Step 3. Choose one of the three copy options. You can click the three options one by one, preview the copy effect and make a final decision.

 
Step 4. This interface will tell you how to boot from the new disk. Then you should press “Finish” to back to the main interface.

 
Step 5. In this interface, you can preview the effect of “Migrate OS to SSD/HD Wizard”, and press “Apply” to save the changes.

 
After these five steps, the Windows Server operating system is migrated to the new hard drive you can use it directly. See, this method is easy and effective.
