How to decrypt an encrypted folder

Folder encryption is a common way to protect personal and confidential files. When we need to protect certain files or folders from being accessed or viewed by others, we can choose to encrypt the folder. However, sometimes when we no longer need to encrypt a certain folder, we need to know how to unencrypt the folder.

The method of decrypting a folder varies slightly depending on the operating system. In this article, I will introduce the steps to decrypt folders under Windows and Mac systems.

For Windows systems:

1. Open the location of the encrypted folder and select the folder to be decrypted.
2. Right-click the folder and select "Properties".
3. In the folder properties window, select the "Advanced" option.
4. In the "Advanced Properties" window, uncheck the "Encrypt content to protect data" option.
5. Click the "OK" button to save changes.
6. The system will prompt whether you want to decrypt all files in the encrypted folder, select "OK".
7. Wait for the system to complete the decryption process.

For Mac system:

1. Open the location of the encrypted folder and select the folder to be decrypted.
2. Click the File menu and select Get Info.
3. In the pop-up information window, find the "General" option.
4. Under the "General" option, find the "Protection" column. If "Encrypted" is displayed here, it proves that the folder has been encrypted.
5. Click the "lock" icon and enter the administrator password to unlock the settings.
6. After unlocking, click the drop-down menu next to "Protect" and select the "No Encryption" option.
7. Close the information window.

It should be noted that decrypting a folder may require administrator rights. If you are not the owner of the folder or do not have the corresponding permissions, you may not be able to successfully decrypt the folder.

In addition, you may be prompted to back up the encryption certificate and key during the process of decrypting the folder. If you have backed up the encryption certificate and key before, you can choose to back up and import them to ensure a smooth decryption process.

When you unencrypt a folder, the files in the originally encrypted folder will be restored to normal files and can be accessed and viewed by other users. So, be sure to think twice before decrypting a folder to make sure no one will use your private files illegally.

When using the folder encryption function, we should realize that encryption is only a security method and cannot be completely relied on to protect private files. In addition to encryption, we should also take other measures such as setting strong passwords, regular backups, using secure cloud storage, etc. to ensure the security of files. This way, we can keep personal and confidential files safe even if the folder's encryption is removed.
