How can I manually compress a folder using WinXP compressed folder(not ZIP)
I have set a folder to compressed and it got compressed thereafter.
However, each new file added to it won't get compressed. What can I do? What could be the reason? The files in that folder get downloaded via internet and used immediatly (UT2004 cache). Any ideas? Thx. -- Bye, Andreas M. |

How can I manually compress a folder using WinXP compressed folder (not ZIP)

I think you are referring to this feature, which can be used on an NTFS formatted partition. In Windows Explorer right click on any folder and select Properties, General, Advanced and check the box before Compress contents to save Disk Space. File compression is a process you can do not a setting for the folder that ensures the contents are automatically compressed every time you add items to the folder. With some files compression conveys little benefit. You need to right click on the file, select Properties and compare the File Size to Size on Disk to see the gain in disk space. Obviously it is hardly worth the effort to compress small files. If the file is regularly accessed compressing the file adversely affects system performance as compressed files take longer to open. Uninstall folders in your Windows folder typically: $NtServicePackUninstall$ and $NtUninstallKB282010$ etc are files that when compressed do give significant disk space gains. -- Hope this helps.

Thanks for clearing things up a little, my wording was too vague. I have already set this flag on a folder and the files got compressed therein, shrinking contents by about a 40%-50%. However, each new file written to this folder does /not/ get compressed. I believe it may have to do with the application (UT2004) doing something to the folder (ie: locking it or so) while running. This is why I was wondering how/whether I can invoke NTFS file-system level compression manually on these files. typically: $NtServicePackUninstall$ and $NtUninstallKB282010$ etc are files that when compressed do give significant disk space gains. True. It seems Windows set these folders automatically to compressed already, since they are compressed here and I did not set that manually. -- Bye, Andreas M. |

File Compression is a feature available as part of the operating system. Your reference to UT2004 threw me as I have never before encountered the software. Using Google I now appreciate what you are referring to. UT2004 incorporates a file compression option, which is separate from the Microsoft feature. The UT2004 feature is more like WinZip software. The file is compressed so that it can be transported from one location to another in a compressed state. There is more about UT2004 compression in the link which follows: http://www.ataricommunity.com/forums...d.php?t=523701 Returning to the Microsoft feature. Automatic file compression can be carried out using Disk CleanUp. Compress Old Files - Windows can compress files that you have not used recently. Compressing files saves disk space, but you can still use the files. No files are deleted. Because files are compressed at different rates, the displayed amount of disk space that you will gain is approximate. An Options button permits you to specify the number of days to wait before Disk Cleanup compresses an unused file. Source: How to Automate the Disk Cleanup Tool in Windows XP http://support.microsoft.com/kb/315246 When using Disk CleanUp many users are frustrated by the length of time time it takes to load Disk CleanUp because it computes an approximate saving in disk space. This frustration is often voiced in these newsgroups. It is clear that Disk CleanUp is selective as to which files it compresses both as to type and age. I do not know of any list as to which types are iincluded for compression and which excluded. I would imagine there is a list somewhere. As a file is only compressed after the expiry of XX days you will find, as you have noticed, folders containing some files compressed and others not compressed. You can right click on the folder and manually compress the contents of the folder regardless of the age of the file at any time. -- Hope this helps.

As already stated, I can compress files with NTFS file-compression. Actually, I was able to go from 34MB free to 400MB free when compressing the UT2004 map and data files in my cache\ folder. So they do indeed compress very nice. Returning to the Microsoft feature. Automatic file compression can be carried out using Disk CleanUp. DiskCleanup is the cleanup, that offers you to free up space once a disk is below the threshold of free space. I know this utility and use it often. containing some files compressed and others not compressed. You can right click on the folder and manually compress the contents of the folder regardless of the age of the file at any time. Yes, this is what I am talking about. I right clicked the folder of UT2004, which contains the cached (in-game-downloads) data-files, selected "compress this folder" and the compression was very nice. But since I have other folders put under compression to I was wondering, why the UT2004/cache/ folder does not get compressed automatically, while all my other folders, which are set to be compressed automatically compress all files therein. As soon as I download new files into the cache folder, which is set to compress=true, they do not get compressed. Hence my question, whether there is a way to invoke NTFS file-compression on files manually, without decompressing the folder and then recompressing it again, so to gain advantage of compression for any new files. Thanks for your efforts. -- Bye, Andreas M. |

So they do indeed compress very nice. Are they files that the system uses when you play the game? If yes then compression will slow the computer. Are you short of free disk space? There are other other ways to increase free disk space? Returning to the Microsoft feature. Automatic file compression can be carried out using Disk CleanUp.

If you compress files that you regularly access you slow down system performance! But since I have other folders put under compression to I was wondering, why the UT2004/cache/ folder does not get compressed automatically, If there are lists of files considered / not considered for compression it could be that the contents of the folder are the list not for compression.Secondly if you regulatly use the files they will not become old enough. It is speculation but some users think Disk CleanUp reads access dates rather than the date the file was created or modified. while all my other folders, which are set to be compressed automatically compress all files therein. As soon as I download new files into the cache folder, which is set to compress=true, they do not get compressed. Hence my question, whether there is a way to invoke NTFS file-compression on files manually, without decompressing the folder and then recompressing it again, so to gain advantage of compression for any new files. You only to compress the folder again but it is quicker to compress the particular item that is not compressed. You cannot compress items in use. Thus change logs in the latest System Restore point cannot be compressed until the next System Restore Point has been created. Thanks for your efforts. Your welcome. -- Hope this helps.
