怎么显示电脑里隐藏的文件夹？

要修改注册表的
方法一：新建文本改名*.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL] "CheckedValue"=dword:00000001

方法二：Show.reg
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden]
"Text"="@shell32.dll,-30499"
"Type"="group"
"Bitmap"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,\
00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,53,00,\
48,00,45,00,4c,00,4c,00,33,00,32,00,2e,00,64,00,6c,00,6c,00,2c,00,34,00,00,\
00
"HelpID"="shell.hlp#51131"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\NOHIDDEN]
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"Text"="@shell32.dll,-30501"
"Type"="radio"
"CheckedValue"=dword:00000002
"ValueName"="Hidden"
"DefaultValue"=dword:00000002
"HKeyRoot"=dword:80000001
"HelpID"="shell.hlp#51104"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL]
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"Text"="@shell32.dll,-30500"
"Type"="radio"
"CheckedValue"=dword:00000001
"ValueName"="Hidden"
"DefaultValue"=dword:00000002
"HKeyRoot"=dword:80000001
"HelpID"="shell.hlp#51105"

然后双击导入注册表，搞定！(xp下成功)
计算机重启后删除: 木马程序 Trojan.Win32.Agent.ut 文件: C:\windows\rsvpsp.dll

1.解决扩展名不能显示问题：
修改注册表中HKEY_LOCAL_MACHINE/SOFTWARE/MICORSOFT/WINDOWS/
CURRENTVERSION/EXPLORE/ADVANCED/FOLDER/HIDDEN/HIDDEN/
HIDEFILEEXT/UcheckedValue的值：0为显示，1位不显示。

还有一个‘隐藏受保护的文件’勾选一下。如果任然没有的话就可能视频不见了

不可能 要么就就是重装系统了的
你看别的盘里能不能显示 要是能那就是视频没了
