关于

-------------------------------------------------- ------------------------------

此存储库包含PowerShell脚本和7-Zip的64位PE二进制文件

v18.05的CLI工具。

所述PowerShell脚本查找给定目录中的每个.7z和.zip文件，以及

使用强大的压缩算法重新打包它们。这可以节省几百

高级用户的“下载”文件夹中的兆字节数;但它确实闪耀的地方是

当你使用某种下载使用的包管理器或mod管理器时

低于恒星的压缩强度。

作为一个案例，我在每个文件夹上运行此脚本

`％应用程序数据\漫游\涡\ Downloads`。我的SkyrimSE文件夹（减去.rar文件）了

从26.6GiBs到25.1GiBs  - 节省1.5GiBs，或约6％！虽然6％可能

看起来并不多，有几个档案在之后减少了25％以上

再压缩。总数是6％而不是25％的原因是因为

大多数26.6GiBs [谢天谢地]已经被最大限度地压缩了。之间

Vortex的SkyrimSE和Skyrim下载文件夹，我的用户下载文件夹，

我大概节省了大约2GiB的空间而没有删除任何东西。

“为什么有人会使用弱压缩算法？”，你可能会想知道。

嗯，有时候一个较弱的压缩算法是有用的 - 

通常用于需要经常访问的数据（一个很好的例子）

一个用于轻压缩的用例，是透明的，分区级压缩。）。

但是当你有很多你不想删除的存档数据时就是这样

主要是收集灰尘，用更强大的压缩算法重新包装它

可以是一件好事。

用法

-------------------------------------------------- ------------------------------

`$ archive-repacker.ps1

[路径\到\目录\到\优化]

[留空，除非你想在提取后暂停]`

提取后暂停的选项非常有用 - 您可以使用它

例如，中断运行纹理优化器的时间段，并节省更多空间。

笔记

-------------------------------------------------- ------------------------------

如果您仍在使用32位操作系统，则需要下载32位版本的

7z.exe。最新版本可以在这里找到：www#7-zip#org/download.html。

当前配置此脚本的方式，每个存档的内容将

失去修改日期。这会获得略微更好的压缩比。

虽然这对最终用户来说可能没问题，但对于mod作者来说也不太可能。如果

您正在使用此脚本来优化您自己的存档，您可以保留它

通过删除`，' -  mtc-'`的所有实例来修改日期。

如果您想使用这些设置创建存档而无需使用

在此脚本中，您可以将7-Zip文件管理器配置为强制创建

压缩档案。为此，请创建一个新存档，然后使用以下命令

选项：

 - 存档格式：.7z

 - 压缩等级：超

 - 压缩方法：LZMA2

 - 字典大小：128 MB

  （如果没有太多RAM，你可能需要减少这个。使用128MB DS，我

  每个大型档案馆都使用大约4GiB的RAM。）

  （请注意，32位计算机的最大容量为128MB。）

 - 字号：273

  （Afaik，这里没有理由不使用最大值。）

 - 实心块尺寸：实心

  （这会产生巨大的差异。）

请求归档创建者

-------------------------------------------------- ------------------------------

如果您要创建要通过Internet发布的存档，请

使用强大的压缩形式。使用弱压缩算法（1）浪费

带宽（这会给主机和用户带来额外的费用。），（2）进行下载

较慢，（3）浪费了服务器主机和最终用户的磁盘空间。

创建档案时，请不要使用.rar等专有格式。这些

格式是（1）性能和压缩比通常较差

Free / Libre格式如.7z，以及（2）这些格式无法创建

免费/自由档案馆，如7z。将所有内容移动到.7z或.zip的标准

在Windows上将使每个人的生活更轻松。

未来的扩张

--------------------------------------------------------------------------------

因为我比Windows更常使用Linux（至少在家里），所以我很可能

最终制作这个脚本的bash版本。 如果我这样做，我甚至可能

试着把它放在AUR上 - 我们只需要看看。 bash版本会

因为我可能支持比PowerShell版本更多的压缩算法

不必使用脚本发送二进制文件。

我可能会添加选项，只查看在特定日期之后修改的文件。

这样，您可以在同一目录上重新运行脚本，而不会浪费时间

重新打包已经优化的档案。 这将需要删除`-stl`

选项，用于将存档的修改日期设置为其文件的修改日期。

此脚本不太可能获得对.rar文件的支持。 如果我确实添加支持，

由于它，我可能无法为rar归档器包含二进制文件

About

--------------------------------------------------------------------------------

This repository contains a PowerShell script and the 64-bit PE binary of 7-Zip

v18.05's CLI tool.

Said PowerShell script finds every .7z and .zip file in a given directory, and

repacks them with a strong compression algorithm.  This can save a few hundred

megabytes in a power user's Downloads folder;  but where it really shines, is

when you use some sort of package manager or mod manager whose downloads use

less-than-stellar compression strengths.

As a case-in-point, I ran this script on each folder in

`%appdata\Roaming\Vortex\Downloads`.  My SkyrimSE folder (minus .rar files) went

from 26.6GiBs, to 25.1GiBs -- a savings of 1.5GiBs, or about 6%!  While 6% may

not seem like much, there were several archives that were over 25% smaller after

recompression.  The reason the total number was 6% instead of 25%, is because

most of that 26.6GiBs was [thankfully] already maximally compressed.  Between

Vortex's SkyrimSE and Skyrim downloads folders, and my user downloads folder,

I saved probably about 2GiBs of without deleting anything.

"Why would anyone ever use a weak compression algorithm?", you might be wondering.

Well, there are actually times when a weaker compression algorithm is useful --

typically for data that needs to be accessed frequently (A really good example of

a use-case for light compression, is transparent, partition-level compression.).

But when you have a lot of archived data that you don't want to delete and that's

mostly just collecting dust, repackaging it with a stronger compression algorithm

can be a great thing to do.

Usage

--------------------------------------------------------------------------------

`$ archive-repacker.ps1

[path\to\directory\to\optimize]

[leave empty unless you want to pause after extractions]`

The option to pause after extractions can be very useful -- you can use this

break period to run texture optimizers, for example, and save even more .

Notes

--------------------------------------------------------------------------------

If you're still using a 32-bit OS, you'll need to download a 32-bit version of

7z.exe.  The latest can be found here: www#7-zip#org/download.html.

The way this script is currently configured, the contents of each archive will

lose their modification dates.  This gets a marginally better compression ratio.

While this may be okay for end-users, it is not likely so for mod authors.  If

you are using this script to optimize your own archive, you can make it preserve

modification dates by removing all instances of `,'-mtc-'`.

If you would like to create archives with these settings without having to use

this script, you can configure the 7-Zip File Manager to create just-as-strongly

compressed archives.  To do this, create a new archive, and use the following

options:

- Archive format: .7z

- Compression level: Ultra

- Compression method: LZMA2

- Dictionary size: 128 MB

  (You may need to reduce this if you don't have much RAM.  With a 128MB DS, I

  was using roughly 4GiBs of RAM for each large archive.)

  (Note that 128MB is the maximum for 32-bit computers.)

- Word size: 273

  (Afaik, there's no reason not to use the maximum, here.)

- Solid Block size: Solid

  (This makes a *huge* difference.)

Request to Archive Creators

--------------------------------------------------------------------------------

If you are creating an archive that you intend to ship over the Internet, please

use a strong form of compression.  Using weak compression algorithms (1) wastes

bandwidth (This costs hosts and users alike extra money.), (2) makes downloads

slower, and (3) wastes disk- for both server hosts and end-users.

When creating archives, please do not use proprietary formats like .rar.  These

formats are (1) usually inferior in performance and compression ratios to

Free/Libre formats like .7z, and (2) these formats cannot be created by

Free/Libre archivers, like 7z.  Moving everything to a standard of .7z or .zip

on Windows will make everyone's lives easier.

Future Expansion

--------------------------------------------------------------------------------

As I use Linux more often than Windows (at least at home), it's likely that I'll

eventually make a bash version of this script.  If and when I do, I might even

try to get it on the AUR -- we'll just have to see.  The bash version will

likely support more compression algorithms than the PowerShell version, since I

won't have to ship their binaries with the script.

I might add the option to only look at files modified after a certain date.

This way, you can re-run the script on the same directory, without wasting time

repacking already-optimized archives.  This will require the removal of the `-stl`

option, which sets the archive's modification date to that of its files.

This script is unlikely to gain support for .rar files.  If I do ever add support,

I will probably be unable to include the binary for the rar archiver, due to its

proprietary license.
