Unsetting Attribute "Protected Operating System File/Folder"

by Donotalo / August 11, 2009 4:45 PM PDT

My OS is Windows XP SP2. My sister bring home with a pen drive which contains many files and folders cannot be seen unless "Hide Protected Operating System Files" from Folder Options > View is unchecked. From the properties dialog box of those files/folders, it can be seen that "Hidden" is checked and grayed out, so it cannot be unchecked.

I'd like to unset this protected OS file attribute from those files/folders so that they can be seen without unchecking "Hide Protected Operating System Files." How can I do that?

Thanks for your time.

Why would anyone copy files to an external USB drive like a pen drive, then hide them?

If you can copy them across from the pen drive to your hard drive, perhaps you can then change their attributes?

In reply to: Strange.

Those files and folders were attributed as protected operating system file on the computer from which my sister copied them, those are just lecture notes. I guess it is done by a virus, cause that pen drive also contained viruses.

I searched net but couldn't find solution of how to unset the "protected operating system file" attribute.

Those viruses.
by MarkFlax Forum moderator / August 12, 2009 4:50 AM PDT

As well as the other advice given, I assume that you have scanned that pen drive with an anti-virus scanner, and then an anti-malware scanner like Malwarebyte's Anti-malware;

Otherwise, connecting that pen drive to your computer allows the viruses to propogate into your system.

Also, you will need to get your sister to scan her own computer for viruses and other malware if that is where these viruses came from.

It's all about File Attributes.

Why not explore File Attributes and how to change them? There is plenty written about this so I'll stop here.

Removing system hidden and protected attributes from windows
by CompNerd007 / April 23, 2013 7:32 AM PDT

open a command prompt window and type in "ATTRIB ['file path']\['file name'] -s -h"

For Example: "ATTRIB C:\USERS\ADMIN\DOWNLOADS\7z920-x64.msi -S -H" and press enter.

You can also use a wildcard (*)

For example: "ATTRIB C:\USERS\ADMIN\DOWNLOADS\FILE* -S -H" and this selects every file in that path that starts with "FILE".

replace "-" with a "+" to add the above attributes to a file.
