NTFS File Compression (Advanced Button Missing) XP Home SP2
Hi,
I have a single HDD with several NTFS Partitions: C: D: E: etc. C: is my System partition - XP Home SP2. I can compress files (i.e.. the 'Advanced' Button is available) on all Partitions except C: C: is NTFS as are all other Partitions - How do I get the 'Advanced' Button back? Any help appreciated. Thanks, Colin |
1. Open My Computer.
2. Right-click the drive you want to compress. 3. Click Properties. 4. On the General tab, select the Compress drive to save disk space check box, and then click OK. 5. In Confirm Attribute Changes, select the option you want. Compress drive to save disk space [[Specifies that this NTFS drive be compressed. By default, only files in the root directory are compressed automatically. To have Windows compress all folders on this drive, select the Also compress subfolders check box in the message that appears.]] -- Hope this helps. Let us know.

Hi Wes,
Thanks for the reply. Unfortunately, that's the problem - The option to 'Compress' isn't there. Although C: is an NTFS Partition like all my others, the CheckBox option to 'Compress' is absent from PropertiesGeneral. Likewise, the 'Advanced' Button is missing when I select 'Properties' for any Files or Folders on the C: Drive. All my other NTFS Partitions' 'Properties' work as expected. I think that the C: Partition was originally FAT32, and was converted to NTFS; whereas, all the other NTFS Partitions were created from scratch. Obviously, FAT32 Partitions don't support 'Compression' - I was wondering if despite coversion to NTFS, there is a Flag set somewhere (in the Registry perhaps?) which is still set to indicate FAT32?

Colin,
On that same General tab of C: Properties, what info is listed for Type: and File System:? Local Disk and NTFS? -- Hope this helps. Let us know.

It may not be a good idea to compress the c: drive???
A little compression goes a long way. In general, NTFS compression is most effective when used on files that are not already compressed. Bitmap images, Microsoft Word documents, and database files are highly compressible. Because music files (in MP3 and WMA format) and JPEG or GIF images are already compressed, NTFS compression provides little benefit and incurs a noticeable performance hit. By all means, avoid compressing the folders that contain Windows system files and log files that the operating system uses regularly. The negative effect on performance is especially severe here. XP Inside Out, MS Press, excerpts .. For security and performance reasons, encryption and compression are mutually exclusive attributes for files stored on an NTFS volume. If the file is compressed, it can’t be encrypted, and vice versa. Might apply j;-) "News Group" wrote: Hi Wes, Thanks for the reply.

Hi Wes,
Type: Local Disk File System: NTFS Also, whereas the correctly functioning NTFS PropertiesGeneral has CheckBoxes: Read Only Hidden and has the CheckBox for 'Archive' thru the 'Advanced' Button; The C: Drive Folders and Files (all with 'Advanced' Button absent) have all three CheckBoxes on PropertiesGeneral: Read Only Hidden Archive I've run CHKDSK and corrected all errors. If I can give any further info. or try anything, please let me know. Disk Manager, Defragmenter, msinfo32 all recognise the C: Drive as NTFS. Thanks you for your help, Colin.

Hi,
To avoid any misunderstanding: I only want to Compress selected files on the C: Partition; not the whole Drive. The system isn't mine, and (as a matter of courtesy) I don't want to return it with known problems.

Colin,
I am at a loss. Does the compact command work on C:?

Hi Wes,
You've just found the problem - Thank you. The 'Compact' command doesn't work. It fails with the error: "The filesystem does not support compression or the cluster size is larger than 4096 bytes" When I run chkdsk: The drive has 16K Clusters. Using Paragon's Hard Disk Manager, I reduced the Cluster Size to 4KB: This fixed the problem. The 'Advanced Button' has returned, as has the C: Drive Compress CheckBox. Thank you for all your help - If you hadn't asked me to try the 'Compact' command, I've no idea how long it would have taken me to fix the issue. Once again Wes, many thanks.
