How to Compress and Decompress a Folder or File with NTFS Compression in Vista and Windows 7

information   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 will not be able to encrypt an NTFS compressed file until decrypted first.

Note   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   Warning
This is not the same as the built-in Zipped Compression used for creating ZIP files in Vista and Windows 7.


EXAMPLE: Folder not Compressed (Decompressed) and Folder Compressed
NOTE:
Notice that the text is now blue to show it is compressed.

Hello James, and welcome to Vista Forums.

I'm not sure what you are wanting. The files may have been compressed separately, or when the folder was uncompressed, the contents (subfolders & files) were not selected to be uncompressed as well.
