When I reinstall Vista or Windows 7, I always do one thing in common for all drives except system file drives. I enable NTFS compression. If you are using this feature already, you might have noticed a huge gain in your hard disk space.
But, if you like to enable this compression for multimedia files like MP3 and Divx, note that Windows can’t compress these files any further. And, if you think that this will slow down your system, believe me, you won’t see noticeable change in system performance.
You need to follow these steps to enable NTFS Compression:
Step 1: Right click on any folder or file or drive and choose Properties, then click Advanced.
(To compress any drive simple check the box named “Enable disk compression to save disk space”)
Step 2: Check the box named ‘Compress contents to save disk space’.
Step 3: In the next screen, select the option called ‘Apply changes to this folder, sub folders and files (Choose this option only if you like to compress the folders inside and the files within).
Step 4: Click OK to start the compression. It might take few minutes depending on the size of the file or folder.
Step 5: Once Windows finishes its task open the Properties to see how much disk space you have gained just now.
If you’re on Windows 10, we recommend you go through our how to compress Windows 10 install files and folders guide for step-by-step instructions.
