Simple Tip to Enable File and Folder Compression

The NTFS file system employed by windows has an integral compression feature known as NTFS compression. With a few clicks, you can enable file and folder compression. The process to “enable file and folder compression” will take up less space on your hard drive. On top of that, you can still gain access to the files normally.

Using NTFS compression consists of a trade-off between CPU time and drive activity. Compression will continue to work better using types of situations and with certain types of files.

Why Enable File and Folder Compression

You should enable file and folder compression as it compresses the complete partition with windows file compression. Everything on the partition will be compressed, as well as any new files added later. You can uncheck file and folder compression on files and folders following the fact, but this isn’t typical.

If you don’t are starving for drive space and/or drive performance isn’t a concern for data upon this drive, then you don’t have to enable file and folder compression off of the bat.

While the process to enable file and folder compression can save drive space, compressing data can adversely influence performance. NTFS compression gets the pursuing performance characteristics. When you replicate or move a compressed NTFS file to another folder, NTFS decompresses the file, copies or steps the file to the new location, and then recompresses the file. This pattern occurs even though the file is copied or migrated between folders on a single computer. Compressed files are also widened before copying on the network, so NTFS compression will not save network bandwidth.

Because NTFS compression is processor-intensive, the performance cost is more noticeable on machines, which are generally processor-bound. Heavily filled machines with a great deal of write traffic are poor prospects for data compression. However, you might not exactly experience significant performance degradation with read-only, read-mostly, or gently loaded servers.

Program Compatibility

If you run an application that uses transfer logging which constantly creates a database or log, configures this program to store its files on the volume that’s not compressed. If an application modifies data through mapped areas in a compressed file, this program can produce “Dirty” web pages faster than the mapped copywriter can write them. Programs such as Microsoft message queuing (also called MSMQ) do not use the enable file and folder compression process for this reason issue.

Because individual home folders and roaming information use plenty of reading and writing procedures, Microsoft recommends that you put user home folders and roaming information on a level that will not have NTFS compression on the actual folder or on the quantity root. Specific users may still enable file and folder compression. However, the overall amount of compressed files and folders is smaller. On machines that coordinator compressed volumes, you need to use careful performance monitoring to find out if the CPU has enough capacity to aid the compress/decompress functions that are being performed.

Benefits and Drawbacks to Enable File and Folder Compression

Here are the pros and cons that you can get after you enable file and folder compression.

For me, there are two big ones.

Compression is work. A very important factor that compression algorithms show is that they might need calculation. Which means when you compress or decompress a file on your pc, your CPU must do more work than if the file weren’t compressed. Different algorithms have different computation characteristics. Some need a lot of CPU control to compress the info, as the decompression can be lightning fast. Others compress relatively improperly but take less time to do it.

Compressing files that already are compressed doesn’t help. A file that was already compressed by the relatively good compression algorithm will typically not compress well if you make an effort to compress it again with another. In truth, in the most detrimental circumstance, “Compressing” a compressed file can make it bigger. Many files you utilize every day already are compressed. Typically, music, video recording, and image platforms already are using compression algorithms within the file format. Mp3, jpeg, mpg, and similar file types are already compressed and typically do not advantage much, if, from efforts to compress them further.

When to Enable File and Folder Compression

I’d consider the next points to enable file and folder compression:

  • If the files you’re considering compressing are being used infrequently, they could be individuals. The “Old files” from a drive cleanup tool probably fall under this category.
  • If the files you’re considering compressing aren’t already compressed, it might make sense. There is no method for me to really know what files drive cleanup is directing you towards, therefore I can’t say how this may connect with you.
  • If you have a robust enough CPU, you may be in a position to compress files used more often rather than notice. I definitely wouldn’t compress files I take advantage of frequently on a mature machine. It can decelerate your machine as the CPU gets more involved with every disk gain access to.
  • Recognize that compressed files and compressed file systems are much harder to recuperate in case of an accident. Make sure you’re properly backed up.

Enable File and Folder Compression Is Trade-offs

NTFS compression makes files smaller on your hard drive. You can gain access to these files normally – no dependence on troublesome zipping and unzipping. As with all file compression systems, your personal computer must use additional CPU time for decompression when it starts the file.

However, the enable file and folder compression won’t necessarily mean it will require any more to start the file. Modern CPUs are incredibly fast. But drive input/output rates of speed haven’t improved practically as much. Look at a 5 MB uncompressed record. When you download it, the computer must copy 5 MB from the drive to your ram memory. If that same file were compressed and used 4 MB on the drive, the computer would copy only 4 MB from the drive. The CPU would need to spend time decompressing the file. But this may happen rapidly. It could even be faster to download the compressed file and decompress it because drive type/output is so poor.

On the computer with a poor hard disk drive and an easy CPU – like a laptop with a high-end CPU but a slow-moving, energy conserving physical hard disk drive, you might see faster file launching times for compressed files.

This is also true as NTFS compression isn’t very ambitious in its compression. A test discovered that it compressed significantly less when compared to a tool like 7-zip. It gets to higher compression ratios by using more CPU time.

When to use Enable File and Folder Compression Process

The process to enable file and folder compression is fantastic for:

  • Files you hardly ever gain access to. (If you never gain access to the files, the actual slow-down when being able to access them is unnoticeable.)

Moreover, What You Can Do With BackTrack Linux

  • Files in an uncompressed format. (Office documents, content material files, and pdf could see a significant decrease in file size. The mp3s and videos already are stored in a compressed format and won’t reduce much, if.)
  • Conserving space on small size Solid State Drives. (Caution: using compression will cause more writes to your sturdy state drive, possibly decreasing its lifetime. However, you might gain even more functional space.)
  • PCs with fast CPUs and gradual hard disks.
NTFS Compression Shouldn’t be Used for:
  • Windows system files and other program files. Using the process to enable file and folder compression here can lessen your computer’s performance and possibly cause other mistakes.
  • Servers where in fact the CPU gets heavy use. On today’s desktop or laptop, the CPU rests within an idle state almost all of the time. This allows it to decompress the files quickly. If you are using NTFS compression on a server with a higher CPU weight, the server’s CPU weight will increase and it’ll take longer to gain access to files.
  • Files in a compressed format. (You will not see a lot of a noticeable difference by compressing your music or video tutorial collections.)
  • Computers with slow-moving CPUs, such as notebooks with low-voltage power-saving potato chips. However, if the laptop has an extremely slow hard disk drive, it’s unclear whether compression would help or injured performance.

How to Enable File and Folder Compression

Now you realize which files you should compress. Also, just why you mustn’t compress your complete hard drive or your windows system folders. You could start compressing some file nows. Windows gives you to compress a person file, a folder, or even a whole drive. Although you mustn’t compress one’s body drive.

To begin with, the enable file and folder compression, right-click the file, folder, or drive you to want to compress and choose properties.

Enable File and Folder Compression 1

Click on the advanced button, available under the attributes.

Enable File and Folder Compression 2

Enable the compress contents to save drive space check field and click okay two times.

Enable File and Folder Compression 3

If you empowered compression for a folder, windows will ask you whether additionally, you want to encrypt subfolders and files.

Enable File and Folder Compression 4

In this example, we kept some space by compressing a folder of word files from 356 kb to 255 kb. You will see a 40% reduction. The files are uncompressed, so we observed a huge improvement here.

Compare the scale of drive field to observe how much space you preserved.

Enable File and Folder Compression 5

Compressed files and folders are determined by their blue titles in windows explorer.

Enable File and Folder Compression 6

To uncompress these files in the foreseeable future, go back to their advanced elements and uncheck the compress checkbox.


You merely need to enable file and folder compression if you are working frantically low on drive space that you are not. It is advisable to leave the choice impaired. As you rightly explain, backup and imaging software offer compression anyhow. You need to use compression for storage space only. Usually, it’s safe to use NTFS compression. Particularly, when you have some type of computer with a really fast CPU and hard drive, like a solid-state drive. On the other hand, if you have a low-end tablet or laptop, or if you employ an old laptop or computer, You should drop the enable file and folder compression option and consider to obtain a bigger drive instead.

Getting a greater exterior hard drive will often make more sense than using compression. More capacity means more room to store files and never have to feel the compression and decompression process that can impact system performance. And yes, you can enable file and folder compression on USB display drives and an SD card. However, by using a hard drive is your very best choice. The quantity of storage space it can save you will always change, and it’ll rely on many factors. NTFS compression has been made to be light in weight and fast, meaning frequently the compression proportion may very well be significantly less than using other compression systems within third-party tools.

It ought to be known that compressed files have to be decompressed before copying in the network. This means NTFS compression will not save network bandwidth. You can enable file and folder compression. But if you need to save lots of bandwidth, you should think about using zip.
