Click "*More info*" and "*Run anyway*" if you judge things to be above-board. 23 | 24 | Note this is beta software and comes with no warranty. 25 | 26 | ## Features 27 | 28 | ### Real-time Progress Updates 29 | 30 | Compactor's directory analysis updates as it goes. You too can experience the satisfaction of watching the disk-space used counter tick down with each file compressed. 31 | 32 | ### Pause, Resume, Stop 33 | 34 | All operations can be paused and interrupted safely at any time. Compactor will finish off what it's doing and stop, or restart where it left off. 35 | 36 | ### Compresstimation 37 | 38 | Compactor performs a statistical compressibility check on larger files before passing them off to Windows for compaction. A large incompressible file can be skipped in less than a second instead of tying up your disk for minutes for zero benefit. 39 | 40 | ### Machine Learning 41 | 42 | Using advanced condition-based AI logic, Compactor can skip over files that have been previously found to be incompressible, making re-running Compactor on a previously compressed folder much quicker. 43 | 44 | (Yes, it's an if statement and a trivial hash database, hush) 45 | 46 | ### Scalable and Fast 47 | 48 | Written in [Rust], a modern compiled systems programming language from Mozilla, Compactor can cope easily with large folders containing millions of files. 49 | 50 | ![](https://i.imgur.com/VxyJmgR.png) 51 | 52 | ## Caveats 53 | 54 | ### Beta Software 55 | 56 | While it has been used successfully by thousands of people, Compactor should be used with care. It is intended for compressing replacable software, not precious files. 57 | 58 | **Make backups**. Report bugs. Be nice. You are reminded: 59 | 60 | ``` 61 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 62 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 63 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE 64 | AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER 65 | LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, 66 | OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE 67 | SOFTWARE. 68 | ``` 69 | 70 | It's in shouty legal text so you know I mean it. 71 | 72 | ### Data Corruption 73 | 74 | There has been [one report][#40] of data corruption with open SQLite database files. The author has been unable to reproduce this, but file locking was added to version 0.10 which should prevent them from being modified. 75 | 76 | ### Permissions 77 | 78 | Compactor currently has no mechanism to elevate its privileges using UAC for protected files. If you're using a limited account you may need to run the program with elevated permissions. 79 | 80 | Be careful what you compress. System files should be skipped automatically, and the Windows folder should be in the list of default exclusions (if you want to compact Windows, check out its [CompactOS] feature), but you almost certainly don't want to blindly run this across your entire `C:\` drive. 81 | 82 | ### Modifiable Files 83 | 84 | Compaction is designed for **files that rarely change** — any modifications result in the file being uncompressed in its entirety. In fact, simply opening a file in write mode will *hang* until the file is uncompressed, even if no changes are made. 85 | 86 | This generally doesn't matter much for application folders, but it's not great for databases, logs, virtual machine images, and various other things that *hopefully* mostly live elsewhere. 87 | 88 | If a game uses large files and in-place binary patching for updates, it might be worth adding to the exclusions list. 89 | 90 | ### Compatibility with Other Operating Systems 91 | 92 | Compaction is only supported on Windows 10 - earlier versions of Windows will be unable to access compressed files, though the rest of the filesystem should remain fully accessible. 93 | 94 | Linux and other operating systems will experience similar issues if the NTFS driver they're using lacks support. As of time of writing, NTFS-3G has a [third-party plugin for the feature](https://github.com/ebiggers/ntfs-3g-system-compression). 95 | 96 | This is available on FreeBSD under [`sysutils/fusefs-ntfs-compression`](https://www.freshports.org/sysutils/fusefs-ntfs-compression/), while users of lesser platforms may need to [manually install it](https://wiki.archlinux.org/index.php/NTFS-3G#Compressed_files) like savages. 97 | 98 | ## Compression Results 99 | 100 | A totally-not-cherry-picked sample of compression results with the default settings: 101 | 102 | | Program | Size | Compacted | Ratio | 103 | |-|-:|-:|-| 104 | | AI War 2 | 2.43 GiB | 1.42 GiB | 0.59x | 105 | | Big Pharma | 1.1 GiB | 711 MiB | 0.37x | 106 | | Crusader Kings 2 | 2.19 GiB | 1.29 GiB | 0.59x | 107 | | Deus Ex MD | 41.31 GiB | 28.06 GiB | 0.68x | 108 | | Infinifactory | 1.71 GiB | 742 MiB | 0.58x | 109 | | Satisfactory | 15.82 GiB | 10.45 GiB | 0.66x | 110 | | Space Engineers | 16.28 GiB | 9.4 GiB | 0.58x | 111 | | Stellaris | 7.76 GiB | 5.21 GiB | 0.67x | 112 | | Subnautica BZ | 10.62 GiB | 6.40 GiB | 0.60x | 113 | | The Long Dark | 7.42 GiB | 5.64 GiB | 0.76x | 114 | | Microsoft SDKs | 5.91 GiB | 2.45 GiB | 0.41x | 115 | | Visual Studio 2017 | 9.63 GiB | 4.77 GiB | 0.50x | 116 | | Windows Kits | 5.38 GiB | 2.03 GiB | 0.38x | 117 | 118 | A more comprehensive database of results is [maintained by the CompactGUI project](https://docs.google.com/spreadsheets/d/14CVXd6PTIYE9XlNpRsxJUGaoUzhC5titIC1rzQHI4yI/edit#gid=0). 119 | 120 | ## Future 121 | 122 | There are many things I want to do with Compactor in future. These include, but are certainly not limited to: 123 | 124 | * Make analysis optional. It isn't fundamentally needed. 125 | * Multithreaded analysis/compaction for SSDs. 126 | * GUI rework of some description. The longer I leave this the better Rust should get at it :P 127 | * Installer. Why does this involve so much XML oh god. 128 | * Sign the binaries/installer. This appears to involve money. 129 | * Scheduled task or a background service for set-it-and-forget-it operation. 130 | 131 | Feature requests can be discussed in the [forum](https://github.com/Freaky/Compactor/discussions), or you may open [an issue](https://github.com/Freaky/Compactor/issues). 132 | 133 | ## Alternatives 134 | 135 | * [`compact.exe`] is a command-line tool that ships with Windows 10. If you're familiar with the command line and batch files, maybe you'd prefer that. Weirdo. 136 | * [CompactGUI] is a popular Visual Basic program that shells out to `compact.exe` to do its work, instead of using the Windows API directly as Compactor does. It has some... performance issues, particularly with larger folders. 137 | * NTFS has supported [LZNT1 compression][lznt1] since 1995, hidden behind a checkbox under `Properties` → `Advanced Attributes`. It's less flexible and has a reputation for poor performance and issues with fragmentation, but is more set-it-and-forget-it. 138 | 139 | Are you aware of any others? Do let me know. 140 | 141 | ## Nerdy Technical Stuff 142 | 143 | Compactor is primarily written in [Rust]. The front-end is basically an embedded website driven by the [web-view] crate. It does *not* depend on any remote resources or open any ports. 144 | 145 | Under the hood it uses [`DeviceIoControl`] with [`FSCTL_SET_EXTERNAL_BACKING`] and [`FSCTL_DELETE_EXTERNAL_BACKING`], and a few functions from [WofApi] (Windows Overlay Filesystem). This is, of course, in part thanks to the [winapi] crate. Eventually I hope to get around to finishing off some of my bindings and contributing them back. 146 | 147 | Compresstimation uses a simple linear sampling algorithm, passing blocks through LZ4 level 1 as a compressibility check and averaging across the entire file. The code is [available on Github][compresstimator]. 148 | 149 | The incompressible-files database is simply an append-only list of SipHash128 path hashes. It should be safe to share between multiple instances if you want to compress different drives at the same time. It lives in `%APPDATA%\Local\Freaky\Compactor`. 150 | 151 | ## Author 152 | 153 | Compactor is written by [Thomas Hurst], a nerdy, aloof weirdo from the north-east of England, and a programmer for about 25 years. 154 | 155 | He mostly works with FreeBSD and focuses on Unix platforms, but uses Windows because he plays games instead of having a social life. 156 | 157 | You can find him on Mastodon at [@Freaky@hachyderm.io], or bug him on IRC as `Freaky` on [libera.chat]. 158 | 159 | [`compact.exe`]: https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/compact
