    How to Enable or Disable NTFS File Compression in Windows

    information   Information
    Windows supports compression for individual files and folders on NTFS volumes using NTFS compression.

    While NTFS file system compression can save disk space, compressing data can adversely affect performance. NTFS compression has the following performance characteristics. When you copy or move a compressed NTFS file to a different folder, NTFS decompresses the file, copies or moves the file to the new location, and then recompresses the file. This behavior occurs even when the file is copied or moved between folders on the same computer. Compressed files are also expanded before copying over the network, so NTFS compression does not save network bandwidth.

    Files or folders saved into an existing compressed folder will automatically be compressed.

    This tutorial will show you how to enable or disable NTFS file compression for all users in Windows 7, Windows 8, and Windows 10.

    You must be signed in as an administrator to enable or disable NTFS file compression.
    Note   Note
    If you disable NTFS file compression, any currently compressed files will still remain compressed. You will also still be able to uncompress any currently compressed files, but you will not be able to compress them again until NTFS compression is enabled.
