When we use the computer, sometimes the file takes up too much space, so we need to compress the file. Today Xiaoxing will share a compression operation that comes with the Windows system.
First, we right-click the file to be compressed, and then click Properties:
Then we can see that the size of this folder is 24.3MB, and the occupied space is 24.5MB. Here we click Advanced:
Check the compressed content to save disk space, click OK:
Continue to click OK:
Choose to apply changes to this folder, subfolders and files, and finally OK:
Here you can see that the folder has turned blue, indicating that the compression has been completed, and then we continue to right-click and click Properties Look at how much space has been reduced:
Now you can see that the file size has not changed, but the occupied space has changed to 13.9MB, indicating that our compression is still effective:
This is the whole process of how to compress Windows NTFS files, yes Isn't it very simple? So go and try it out! ! !
If you want to encrypt this folder, just check the encryption in the option of just compressing the file: after the encryption is
complete, you will find that the folder turns green, and the compression we just performed on the folder It has no effect, and the occupied space has become the previous 24.5MB. From here we can know that the compression and encryption of the NTFS folder cannot be performed at the same time: one more thing, you will find that
this encryption is exactly as you imagined. It’s different, because the encryption you want requires a password to enter the folder, but here you can directly click on the folder to enter. It gives you the feeling that this encryption is fake, and this encryption has a fart. ! ! ! Isn’t this just a change of color:
Don’t worry, let me tell you slowly, this encryption is for users, for example, if you are an encrypted user, other users cannot open your encrypted folder. Do not believe it? Then I'll show you the demo right now.
First of all, I created a common user xiaoxing. I won’t demonstrate how to create a new user here. If you don’t know how to create one, please refer to this article: How to create new users and groups in windows server 2012 . As long as it is a windows system, you can create a new user in this way.
I am using windows server 2012 for the demonstration. Let’s right-click the window icon in the lower left corner, then slide the mouse to shutdown or logout, and click logout: Then select the
user xiaoxing to enter the system:
After entering the system, enter the resource manager to find our management The folder encrypted by the administrator account, here we can see that the folder can still be entered:
Then I clicked a Notepad file, and an access denial window popped up:
If you are still concerned about whether the administrator can open the encrypted file Doubt, then I switch back to the administrator account now, it is still the same, open an encrypted Notepad file to see if it can be opened.
Here we can see that it is opened, and you can still see the specific content:
If you still don't believe my demonstration, then you can try it yourself. But you have to believe that I will definitely not tell you the wrong thing, hehe (manually smirking) then we will meet again by fate! ! !
