当你在文件夹选项里打不开已隐藏的文件时可以用以下方法打开！
造成打不开的原因是：注册表给修改了
方法如下：
新建一个“文本文档”，然后把扩展名改成“reg”
在文本文档导入以下内容：
REGEDIT4
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\explorer\Advanced\Folder\Hidden]
"Text"="隐藏文件"
"Type"="group"
"Bitmap"="C:\\WINDOWS\\SYSTEM\\SHDOC401.DLL,4"
"HelpID"="update.hlp#51131"
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\explorer\Advanced\Folder\Hidden\SHOWALL]
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"Text"="显示所有文件"
"Type"="radio"
"CheckedValue"=dword:00000000
"ValueName"="Hidden"
"DefaultValue"=dword:00000000
"HKeyRoot"=dword:80000001
"HelpID"="update.hlp#51105"
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\explorer\Advanced\Folder\Hidden\NOHIDDEN]
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"Text"="不显示隐藏文件"
"Type"="radio"
"CheckedValue"=dword:00000000
"ValueName"="Hidden"
"DefaultValue"=dword:00000000
"HKeyRoot"=dword:80000001
"HelpID"="update.hlp#51104"
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\explorer\Advanced\Folder\Hidden\NOHIDORSYS]
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"Text"="不显示隐藏文件或系统文件"
"Type"="radio"
"CheckedValue"=dword:00000000
"ValueName"="Hidden"
"DefaultValue"=dword:00000000
"HKeyRoot"=dword:80000001
"HelpID"="update.hlp#51103"
