⑴ 怎样制作解压缩文件夹

首先把这些照片放在一个文件夹里面，然后用鼠标右键单击文件夹-〉添加到压缩文件夹-〉在窗口最左下选择分段压缩大小（1,457,664 - 3.5"）这个是3寸盘的，然后压缩就可以了，把每一个都放入3寸盘，然后考入同一目录，单击一个解压缩就可以了。

PS 需要你有Winrar
不会再问我QQ86881052

⑵ 关于Y560AT-ISE解压文件的问题

更新一下主板驱动试试
驱动下载：
看一下主机后面的主机编号，然后到下列网址，在页面中间第一个对话框把编号输入查找

⑶ 谁能告诉我解压缩文件的WINZIP怎么使用

对于可解压的文件只要选中点鼠标右键就有解压菜单了！
建议你还是使用 winrar 吧，支持的格式比较多，虽然有时候压缩 rar 格式比 zip 格式慢些，但如果设置好了好多时候会压缩比率更大一些！
最主要的是 winzip 解不了 rar ，而 winrar 可以解 zip ！

⑷ 怎样解压ZIP文件

呵呵，zip都不会用，winrar都没有装，就想当黑客了？？？

先要学会走路才好，

建议先安装winrar，然后点击那个zip，解压，选择路径（就先选桌面，找一下感觉），确定。

⑹ 如何打开RAR压缩文件包

可以使用winrar进行解压打开，具体的操作方法为：

1、打开网络，搜索winrar，并点击打开一个下载网站。

⑺ 最大解压文件

上传了500M的zip后发现竟然没有解压，文件的这个选项文件类型显示的是“file
style：data”那该怎么办？是用winrar压缩成的zip的没有exta的选择该怎么办？可是传了好久的······························解压这么大的文件CPU占有率一定很高，会不会被停空间？[]

⑻ 如何解包/编辑/打包android系统的boot.img文件

1
boot映像并不是一个完整的文件系统，它是一种android自定义的文件格式，该格式包括了2K的文件头，后面紧跟着是用gzip压缩过的内核，再后面是一个ramdisk内存盘，然后紧跟着第二阶段的载入器程序（这个载入器程序是可选的，在某些映像中或许没有这部分）。此类文件的定义可以从源代码android-src/system/core/mkbootimg找到一个叫做bootimg.h的文件。

/*
** +-----------------+
** | boot header | 1 page ** +-----------------+
** | kernel | n pages ** +-----------------+
** | ramdisk | m pages ** +-----------------+
** | second stage | o pages ** +-----------------+ **
** n = (kernel_size + page_size - 1) / page_size ** m = (ramdisk_size + page_size - 1) / page_size ** o = (second_size + page_size - 1) / page_size **
** 0. all entities are page_size aligned in flash ** 1. kernel and ramdisk are required (size != 0)
** 2. second is optional (second_size == 0 -> no second) ** 3. load each element (kernel, ramdisk, second) at ** the specified physical address (kernel_addr, etc) ** 4. prepare tags at tag_addr. kernel_args[] is ** appended to the kernel commandline in the tags. ** 5. r0 = 0, r1 = MACHINE_TYPE, r2 = tags_addr ** 6. if second_size != 0: jump to second_addr ** else: jump to kernel_addr */

ramdisk映像是一个最基础的小型文件系统，它包括了初始化系统所需要的全部核心文件，例如:初始化init进程以及init.rc（可以用于设置很多系统的参数）等文件
看这里是不是显得头大呢，，，今天哥们分享的教程是比较简单的，不需要认识这些东西是做什么的，有什么用，。只需要要一个简单的工具就能实现你想要解包boot.img的问题。。。
3
下载一个ROM助手，网络搜索下就行，最好是官网下载，蘑菇论坛。
安装并打开它，在主界面上你会找到“解包IMG”功能的按钮，

4
点击后把你的boot镜像文件加载进去，等待几分钟，就能把boot的镜像解开了 ，，上面提示打开文件夹，点击之后，就能找到boot解开后的全部内容，在这里你想怎么编辑就怎么编辑。

看到木有boot解包就是这么简单，其实ROM助手还可以解包recovery 、userdara等镜像文件。只要用了就看到，步骤和上面的操作时一样的 。

5
K！好了，修改大家就自己去奋斗吧，其实说实话，安卓本来基于LINUX就是在那系统下玩的，用WINDOWS的就比较吃亏了。。截止目前ROM助手还没有打包功能，相信他们开发团队很快就能完善这项功能的说。我这里根据我的经验来分享下如何打包boot镜像文件，这里需要用命令符
开始-运行-cmdd:回车cd boot回车bootimg --repack-bootimg 0x200000 "mem=211M console=null androidboot.hardware=qcom" 2048 4096
出现“output boot.img”的字样就显示打包成功
6
到这里就完全打包解包无压力了，额，recovery userdara 解包打包，就直接按照这个操作步骤即可完成。

⑼ 如何解压文件名是UTF8编码的压缩包

UTF8其实和Unicode是同类，就是在编码方式上不同！
首先UTF8编码后的大小是不一定，不像Unicode编码后的大小是一样的！

我们先来看Unicode的编码：一个英文字母 “a” 和 一个汉字 “好”，编码后都是占用的空间大小是一样的，都是两个字节！

而UTF8编码：一个英文字母“a” 和 一个汉字 “好”，编码后占用的空间大小就不样了，前者是一个字节，后者是三个字节！

现在就让我们来看看UTF8编码的原理吧：
因为一个字母还有一些键盘上的符号加起来只用二进制七位就可以表示出来，而一个字节就是八位，所以UTF8就用一个字节来表式字母和一些键盘上的符号。然而当我们拿到被编码后的一个字节后怎么知道它的组成？它有可能是英文字母的一个字节，也有可能是汉字的三个字节中的一个字节！所以，UTF8是有标志位的！

当要表示的内容是 7位 的时候就用一个字节：0******* 第一个0为标志位，剩下的空间正好可以表示ASCII 0－127 的内容。

当要表示的内容在 8 到 11 位的时候就用两个字节：110***** 10****** 第一个字节的110和第二个字节的10为标志位。

当要表示的内容在 12 到 16 位的时候就用三个字节：1110***** 10****** 10****** 和上面一样，第一个字节的1110和第二、三个字节的10都是标志位，剩下的占湔�每梢员硎竞鹤帧?BR>
以此类推：
四个字节：11110**** 10****** 10****** 10******
五个字节：111110*** 10****** 10****** 10****** 10******
六个字节：1111110** 10****** 10****** 10****** 10****** 10******

UTF-7：A Mail-Safe Transformation Format of Unicode(RFC1642)。这是一种使用 7 位 ASCII 码对 Unicode 码进行转换的编码。它的设计目的仍然是为了在只能传递 7 为编码的邮件网关中传递信息。 UTF-7 对英语字母、数字和常见符号直接显示，而对其他符号用修正的 Base64 编码。符号 + 和 - 号控制编码过程的开始和暂停。所以乱码中如果夹有英文单词，并且相伴有 + 号和 - 号，这就有可能是 UTF-7 编码。

关于UTF7的更多资料如下（都是英语的，如果想具体了解再看）：

A Mail-Safe Transformation Format of Unicode

Status of this Memo

This memo provides information for the Internet community. This memo
does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.

Abstract

The Unicode Standard, version 2.0, and ISO/IEC 10646-1:1993(E) (as
amended) jointly define a character set (hereafter referred to as
Unicode) which encompasses most of the world's writing systems.
However, Internet mail (STD 11, RFC 822) currently supports only 7-
bit US ASCII as a character set. MIME (RFC 2045 through 2049) extends
Internet mail to support different media types and character sets,
and thus could support Unicode in mail messages. MIME neither defines
Unicode as a permitted character set nor specifies how it would be
encoded, although it does provide for the registration of additional
character sets over time.

This document describes a transformation format of Unicode that
contains only 7-bit ASCII octets and is intended to be readable by
humans in the limiting case that the document consists of characters
from the US-ASCII repertoire. It also specifies how this
transformation format is used in the context of MIME and RFC 1641,
"Using Unicode with MIME".

Motivation

Although other transformation formats of Unicode exist and could
conceivably be used in this context (most notably UTF-8, also known
as UTF-2 or UTF-FSS), they suffer the disadvantage that they use
octets in the range decimal 128 through 255 to encode Unicode
characters outside the US-ASCII range. Thus, in the context of mail,
those octets must themselves be encoded. This requires putting text
through two successive encoding processes, and leads to a significant
expansion of characters outside the US-ASCII range, putting non-
English speakers at a disadvantage. For example, using UTF-8 together

with the Quoted-Printable content transfer encoding of MIME
represents US-ASCII characters in one octet, but other characters may
require up to nine octets.

Overview

UTF-7 encodes Unicode characters as US-ASCII octets, together with
shift sequences to encode characters outside that range. For this
purpose, one of the characters in the US-ASCII repertoire is reserved
for use as a shift character.

Many mail gateways and systems cannot handle the entire US-ASCII
character set (those based on EBCDIC, for example), and so UTF-7
contains provisions for encoding characters within US-ASCII in a way
that all mail systems can accomodate.

UTF-7 should normally be used only in the context of 7 bit
transports, such as mail. In other contexts, straight Unicode or
UTF-8 is preferred.

See RFC 1641, "Using Unicode with MIME" for the overall specification
on usage of Unicode transformation formats with MIME.

Definitions

First, the definition of Unicode:

The 16 bit character set Unicode is defined by "The Unicode
Standard, Version 2.0". This character set is identical with the
character repertoire and coding of the international standard
ISO/IEC 10646-1:1993(E); Coded Representation Form=UCS-2;
Subset=300; Implementation Level=3, including the first 7
amendments to 10646 plus editorial corrections.

Note. Unicode 2.0 further specifies the use and interaction of
these character codes beyond the ISO standard. However, any valid
10646 sequence is a valid Unicode sequence, and vice versa;
Unicode supplies interpretations of sequences on which the ISO
standard is silent as to interpretation.

Next, some handy definitions of US-ASCII character subsets:

Set D (directly encoded characters) consists of the following
characters (derived from RFC 1521, Appendix B, which no longer
appears in RFC 2045): the upper and lower case letters A through Z
and a through z, the 10 digits 0-9, and the following nine special
characters (note that "+" and "=" are omitted):

Character ASCII & Unicode Value (decimal)
' 39
( 40
) 41
, 44
- 45
. 46
/ 47
: 58
? 63

Set O (optional direct characters) consists of the following
characters (note that "\" and "~" are omitted):

Character ASCII & Unicode Value (decimal)
! 33
" 34
# 35
$ 36
% 37
& 38
* 42
; 59
< 60
= 61
> 62
@ 64
[ 91
] 93
^ 94
_ 95
' 96
{ 123
| 124
} 125

Rationale. The characters "\" and "~" are omitted because they are
often redefined in variants of ASCII.

Set B (Modified Base 64) is the set of characters in the Base64
alphabet defined in RFC 2045, excluding the pad character "="
(decimal value 61).

Rationale. The pad character = is excluded because UTF-7 is designed
for use within header fields as set forth in RFC 2047. Since the only
readable encoding in RFC 2047 is "Q" (based on RFC 2045's Quoted-
Printable), the "=" character is not available for use (without a lot
of escape sequences). This was very unfortunate but unavoidable. The
"=" character could otherwise have been used as the UTF-7 escape
character as well (rather than using "+").

Note that all characters in US-ASCII have the same value in Unicode
when zero-extended to 16 bits.

UTF-7 Definition

A UTF-7 stream represents 16-bit Unicode characters using 7-bit US-
ASCII octets as follows:

Rule 1: (direct encoding) Unicode characters in set D above may be
encoded directly as their ASCII equivalents. Unicode characters in
Set O may optionally be encoded directly as their ASCII
equivalents, bearing in mind that many of these characters are
illegal in header fields, or may not pass correctly through some
mail gateways.

Rule 2: (Unicode shifted encoding) Any Unicode character sequence
may be encoded using a sequence of characters in set B, when
preceded by the shift character "+" (US-ASCII character value
decimal 43). The "+" signals that subsequent octets are to be
interpreted as elements of the Modified Base64 alphabet until a
character not in that alphabet is encountered. Such characters
include control characters such as carriage returns and line
feeds; thus, a Unicode shifted sequence always terminates at the
of a line. As a special case, if the sequence terminates with the
character "-" (US-ASCII decimal 45) then that character is
absorbed; other terminating characters are not absorbed and are
processed normally.

Note that if the first character after the shifted sequence is "-"
then an extra "-" must be present to terminate the shifted
sequence so that the actual "-" is not itself absorbed.

Rationale. A terminating character is necessary for cases where
the next character after the Modified Base64 sequence is part of
character set B or is itself the terminating character. It can
also enhance readability by delimiting encoded sequences.

Also as a special case, the sequence "+-" may be used to encode
the character "+". A "+" character followed immediately by any
character other than members of set B or "-" is an ill-formed
sequence.

Unicode is encoded using Modified Base64 by first converting
Unicode 16-bit quantities to an octet stream (with the most
significant octet first). Surrogate pairs (UTF-16) are converted
by treating each half of the pair as a separate 16 bit quantity
(i.e., no special treatment). Text with an odd number of octets is
ill-formed. ISO 10646 characters outside the range addressable via
surrogate pairs cannot be encoded.

Rationale. ISO/IEC 10646-1:1993(E) specifies that when characters
the UCS-2 form are serialized as octets, that the most significant
octet appear first. This is also in keeping with common network
practice of choosing a canonical format for transmission.

Rationale. The policy for code point allocation within ISO 10646
and Unicode is that the repertoires be kept synchronized. No code
points will be allocated in ISO 10646 outside the range
addressable by surrogate pairs.

Next, the octet stream is encoded by applying the Base64 content
transfer encoding algorithm as defined in RFC 2045, modified to
omit the "=" pad character. Instead, when encoding, zero bits are
added to pad to a Base64 character boundary. When decoding, any
bits at the end of the Modified Base64 sequence that do not
constitute a complete 16-bit Unicode character are discarded. If
such discarded bits are non-zero the sequence is ill-formed.

Rationale. The pad character "=" is not used when encoding
Modified Base64 because of the conflict with its use as an escape
character for the Q content transfer encoding in RFC 2047 header
fields, as mentioned above.

Rule 3: The space (decimal 32), tab (decimal 9), carriage return
(decimal 13), and line feed (decimal 10) characters may be
directly represented by their ASCII equivalents. However, note
that MIME content transfer encodings have rules concerning the use
of such characters. Usage that does not conform to the
restrictions of RFC 822, for example, would have to be encoded
using MIME content transfer encodings other than 7bit or 8bit,
such as quoted-printable, binary, or base64.

Given this set of rules, Unicode characters which may be encoded via
rules 1 or 3 take one octet per character, and other Unicode
characters are encoded on average with 2 2/3 octets per character

plus one octet to switch into Modified Base64 and an optional octet
to switch out.

Example. The Unicode sequence "A<NOT IDENTICAL TO><ALPHA>."
(hexadecimal 0041,2262,0391,002E) may be encoded as follows:

A+ImIDkQ.

Example. The Unicode sequence "Hi Mom -<WHITE SMILING FACE>-!"
(hexadecimal 0048, 0069, 0020, 004D, 006F, 006D, 0020, 002D, 263A,
002D, 0021) may be encoded as follows:

Hi Mom -+Jjo--!

Example. The Unicode sequence representing the Han characters for
the Japanese word "nihongo" (hexadecimal 65E5,672C,8A9E) may be
encoded as follows:

+ZeVnLIqe-
