How to Compress and Decompress a Folder or File with NTFS Compression in Vista Information | | This will show you how to compress or decompress a folder or file with NTFS Compression to reduce their size. NTFS Compression allows you to save some hard drive space by compressing files and folders to reduce their size. You cannot encrypt an NTFS compressed file. |  | NOTE | | You may notice a decrease in performance when working with NTFS-compressed files. When you open a compressed file, Vista automatically decompresses it for you, and when you close the file, Vista compresses it again. This process may decrease your computers performance since it takes a little longer to open and close a compressed folder or file. |  | WARNING | | This is not Zipped Compression for creating ZIP files. |  | RELATED LINKS:EXAMPLE: Folder not Compressed (Decompressed) and Folder Compressed NOTE: Notice that the text is now blue to show it is compressed.
