whenever i get,install,copy or in general make a new file in my drives they take up twice as much space from the my computer screen, if i see the properties of the files themselves it's the correct size but it takes up twice as much space on the drive. it only happens in drives other than C so i guessed that it's because windows is compressing the files in those NTFS drives and it keeps both versions. but the files keep taking twice as much size for some time,even after it has seemingly finished compressing, sometimes it goes away on its own and sometimes it stays, restarting seems to fix it. am i right? is there anyway to get rid of this without deactivating the NTFS compression?
