P4What s the reason why the file shown on it doesn t show up on the computer?

Maybe it's hidden You open my computer -- Tools -- Folder Options -- View -- show all files and folders.

Maybe it's hidden.

You open My Computer - Tools - Folder Options - View - Show all files and folders.

Your files are hidden, it is recommended to open the hidden files of the computer and look at the My Computer--Tools--Folders-Options-View-Find Show All Files and Folders and Hide Protected System Files option of I passed the picture.

Also, you can right-click on your P4 to see if it's occupied, it means that the contents are hidden.

If there is nothing to suggest formatting, there is something important that cannot be formatted, and once formatted there is nothing.

You can use card bar and nod32 for antivirus, domestic software and they are not a class.

"From p4, all the files are there, but all the files in the computer can't be displayed", this is likely to be the file attribute was changed to hide by the virus, although the virus was cleared, but the file attribute was not changed back.

Set the show hiding method:

Win7 system.

Open "Computer" and find "Organization" "Layout" "Menu Bar" (checked) in the upper left corner of the window. Then you will find an extra row of menus above the window, select "Tools" "Folder Options" "View" in it.

Also select "Show all files and folders" below, then "Apply" - "OK".

I suggest you go for the next mp4 kill tool! It seems that there is one on 360! However, those killing tools are aimed at certain viruses and Trojans! But I think this should work for p4 too!

The best way to do this is to not run the direct format.

Is your computer's P5 program installed, not every computer can use it automatically.

Hidden! All files are displayed.

If it's an ordinary way to bring up the hidden files**, it's very simple, I guess you're poisoned, you try this method first. Open my computer - Tools - Folder Options - View - Show all files and folders, and remove the Hide protected operating system files If you still can't monitor the things in the mp4 after doing this, then you have to go into the registry to change, the method is as follows, 1 Open Start Run the input finger wheel into regedit, open the registry.

hkey_local_machine | software |microsoft | windows | currentversion | explorer | advanced | folder | hidden |showall, change the checkedvalue key to 1

2 But it may still be useless, the hidden file is still not displayed, this is because the virus deleted the original valid dword value checkedvalue after modifying the registration expression to the purpose of the hidden file, created a new invalid string value checkedvalue, and changed the key value to 0!

Method: Delete this checkedvalue key, right-click to create a new DWORD value, name it checkedvalue, and then modify its key value to 1, so that you can choose "Show all hidden files" and "Show system files". If it is reg sz, delete the key value and create a new dword value with the name checkedvalue. The value is 1

If you are using Windows XP system, please copy the following ** to a text document and change the suffix to VBS, so that you know how to display hidden files like watching a movie! dim wsh,j

set wsh="Nayou")

d:"500"%t"

for j=1 to 14

500"Naqiao"

500"Hole in the acres key.

I'll give you an analysis:

One: Your memory is normal.

So why is there no change, first of all, it may be that the files inside you are not lost and are still inside, so why can't you see it? One possibility is that it is hidden.,Just look at the hidden folder.,There's also isolation.,The files inside are considered harmful files by antivirus software.,It will hide it.,And then it's actually still on the disk.,It's just been processed.,It's best to check the disk on OK.。

Second, there is a problem with your memory.

So, first of all, if your P4 disk is not damaged by Zheng Kai, then you right-click, attributes, tools, check errors, and it should be fixed. If it's the last one, then congratulations, your disk has caused an irreparable problem, that is, the memory is lost and shouted.

Of course, if it is returned to the factory for repair, it can be done, but it is not necessary. Of course, if you have someone who is a master to cultivate, you can.

Saying this for the time being, I hope it helps you.
