pdf怎么转换成word格式:我想重做系统，怎样保存我上网时收在收藏夹中的内容？

点击浏览器中的文件选项,选导入导出命令,然后点下一步选导出收藏夹,再在非系统盘新建个文件夹保存就行了.

把这个文件夹里的所有东西copy出来，重装以后在放回去就可以了。
***是你自己的用户名。

C:\Documents and Settings\***\Favorites

可以看看这两个注册表文件
Windows Registry Editor Version 5.00

[HKEY_USERS\S-1-5-21-1715567821-1177238915-725345543-1003\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]

"My Music"="C:\\Documents and Settings\\zzz\\My Documents\\My Music"
"CD Burning"="C:\\Documents and Settings\\zzz\\Local Settings\\Application Data\\Microsoft\\CD Burning"
"My Video"=""
上面的那个没改路径。

下面我改了路径
Windows Registry Editor Version 5.00

[HKEY_USERS\S-1-5-21-515967899-115176313-725345543-1003\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]
"AppData"="C:\\Documents and Settings\\zzz\\Application Data"
"Cookies"="D:\\SYSTEM\\Cookies"
"Desktop"="D:\\SYSTEM\\桌面"
"Favorites"="D:\\SYSTEM\\Favorites"
"NetHood"="C:\\Documents and Settings\\zzz\\NetHood"
"Personal"="E:\\"

"Recent"="C:\\Documents and Settings\\zzz\\Recent"
"SendTo"="D:\\SYSTEM\\SendTo"

"My Music"="E:\\My Music"
"CD Burning"="C:\\Documents and Settings\\zzz\\Local Settings\\Application Data\\Microsoft\\CD Burning"
"My Video"=""
好了这样重启以后，收藏夹会移动到
"Favorites"="D:\\SYSTEM\\Favorites"

不过里面的冬冬你要自己移动过来，以后你添加收藏夹文件的时候就直接添加到D:\\SYSTEM\\Favorites。

不过注意这里的
[HKEY_USERS\S-1-5-21-1715567821-1177238915-725345543-1003
在你机上可能不一样。
可能是这种样子的
[HKEY_USERS\S-1-5-21-××××-×××××-×××××-1003
也就是头尾一样，×的地方是数字，可以打开注册看一看。
