Overview of Hide and Unhide Partition

Hide Partition can be extremely useful when you have some confidential files or sensitive information on the local disk and you want others to stay as far away from it as possible. After you hide a partition, the partition will be invisible to all visitors until you manually unhide it. If one day you want to use it again, simply unhide it and it will then show up again in My Computer and Explorer.

How to Hide Partition

Before you do

  • Download and install AOMEI Partition Assistant on a Windows computer.
  • If there are other applications running on the partition which you are going to hide/unhide, AOMEI Partition Assistant will notify you to close those applications.
  • Move the most frequently used files and applications that you don’t want to hide from the partition which you are going to hide to other partitions.

How to Hide Partitions with Partition Assistant

1. Right-click on the partition which you want to hide (Take the K: partition as an example) to open a pop-up menu. Then, choose "Advanced"->"Hide Partition"

2. You will get a warm prompt as shown in the following screenshot. Please click "OK" to continue.

Click Ok

3. Click "Apply" to execute the operation. After that, the K: partition will be invisible to others, and it will be completely hidden from My Computer and Windows Explorer.


Tips: Unhide Partition shares the same operating steps as "Hide Partition".


Following the steps above, you will get the partition hidden. In this case, the partition will not be displayed in My Computer and Windows File Explorer. And, the data on the hidden partition will also be completely invisible to any visitors.

This feature is mainly used to hide a partition where there is important and sensitive data on it. It helps you protect your data security and privacy. After you unhide the partition, you will view the data on it and use the partition normally.


  • This hidden partition operation will hide/unhide your partition with its content intact.
  • The hidden partition will not be available to use until you unhide it.
  • After you unhide a partition, Windows will randomly reallocate a new drive letter to that partition. This means you may get a drive letter that is different from its original one.
  • Unhide a partition will cause its related shortcuts invalid.



Q: Can I still use the partition and access data on it after it is hidden?

A: No, the partition will not be displayed in your Windows File Explorer so it is unable to directly check and access the partition and data on it.

Q: Will the operation "Hide Partition" cause any data loss?

A: Normally, it will not cause data loss after you hide a partition. It hides the partition drive letter so that it is unable to directly access data on the partition. After you unhide the partition, you can access data and use the partition without a problem.

Q: Why the drive letter is changed after I unhide the partition, for example, it was E: but changed to F: after it is unhidden.

A: It is normal because Windows will randomly reallocate new drive letters for partitions. If the original E: has been allocated to another partition, a new drive letter will be assigned to the unhidden partition.
