Should you Enable File and Folder Compression?

We get asked by several users whether they should enable the NTFS file and folder compression on their disk drives. Usually, when you are initializing a new drive, you are given the option whether you want to enable the file and folder compression or not. There is a choice between options and the outcomes don’t have anything to do with the running of modules except them taking less space.

In this article, we will go through all the explanation and after analyzing the trademarks, decide whether you should enable file and folder compression on your disk drive. Make sure that you are logged in as an administrator on your computer.

NTFS compresses file and folders by first diving the data streams into CUs. After the stream contents are created or changed, the CU in the data stream will automatically be compressed individually. This architecture, in turn, provides the random access of memory very fast since only one CU will need to be decompressed.

What are the Shortcomings of NTFS File/Folder compression?

NTFS compression is a great thing; it shrinks the size of files in your hard drive and you still don’t have to go through the hassle of zipping and unzipping the files. You can access them like other normal folders. However, like all file compression mechanisms, your computer will take a little more time to open the file since it is performing the decompression steps in the background.

When we said ‘a little more time’, we really meant it. Suppose you have a document whose size is 100 MB. Now, you want to open the file. When you pass the command, the computer will transfer all of those 100 MBs to its main memory module and then launch the application after the instructions are read.

If you have enabled the NTFS compression and the compressed file is 80 MB after the action, it will transfer only 80 MB to the main memory and perform the decompression there. I/O operations are still somewhat slow in the current computing world but once the file is in the memory, it may even be faster to access than a normal file.

Also, if you copy or move an NTFS compressed file to another location, first it will be decompressed, moved, and then compressed again. These files will also be expanded before they are transferred over the internet so there will also be no significant increase in bandwidth (it may even make it a tab slower!).

Moreover, the module is even tested for low usage of resources after performing several experiments on our own. Follow the steps below to make sure that the NTFS file system will help your case out.

When should I use NTFS File/Folder Compression?

In this section, we will give you a brief overview of situations where the NTFS compression will work perfectly and where you should avoid it. All of the reasons might not be valid for you so only relate to the specific needs.

Ideal cases for NTFS Compression

Below are the cases/scenarios where the NTFS file compression will suit you best:

  • Computers which have a faster processing unit but slower disk I/O operations (think of it this way, the compressed file will be able to load to main memory more quickly and can easily be decompressed there instead of transferring the entire file to the memory at once).
  • Misc files which are not formatted yet might be a very good case. When compression is performed on them, they yield a lot of free spaces. These might include PDFs, MP3 documents, and videos, etc.
  • Files which are rarely accessed are also potential candidates. These files, if accessed occasionally, can be compressed and stored away to the corner of the hard drive.
  • NTFS compression might be very beneficial for SSDs which have a limited quota of space available.
  • Files which are sparingly shared over the network can be compressed as well as long as they are transmitted ‘sparingly’.

Worst cases for NTFS Compression

Now like the best cases listed above, here are the worst cases where enabling NTFS compression will cause you negative outcome instead of a positive one.

  • Compression should not be done on system drives and other program files. The computer accesses these modules quite frequently and compressing them will make things slower.
  • Files already in a compressed format will not display any significant progress since they are already compressed.
  • Computers which have slow processing units will also have slower experience on their machines as the load on the processing unit will increase while it does not have the capacity.
  • Servers/computers where the load is heavy are strictly advised not to use the NTFS compression. These machines get numerous requests every time and if you add decompressing on the list, the time will increase drastically.
  • If the directory which you want to compress has games along with its installation files. This will increase the fetch timings of the gaming module and your game will lag drastically.

How to Enable NTFS Compression?

After you have decided whether to use the NTFS compression, you can go ahead and compress the files and folders accordingly. Make sure that you are logged in as an administrator on your computer.

  1. Press Windows + E to launch the File Explorer and navigate to the directory where the file is present.
  2. Once in the required directory, right-click on the file/folder and click on Properties.

    Properties of Folder to Compress
  3. Once in the properties, click on Advanced right next to the attributes.
  4. Now, check the option compress contents to save disk space. This will be present under the heading of Compress or Encrypt attributes.

  5. Make sure that you apply the changes to all the sub-folders as well.
  6. Now, after the compression is complete, you can easily check the new space by opening the properties again.

Note: You can easily diagnose which files are compressed or not by checking whether they have a blue marking or not. A blue marking means that they are compressed.
