How to create a system folder in My Computer

System folder like My Document which appears in My computer are special folders which appear can not be deleted. Now if you want to create something like that, a folder which cannot be deleted!!!! . Here is how you do it to create a folder which cannot be deleted!!. It should work both in XP and VISTA.

However a word of caution, If you don’t know about registry, either back up or don’t try this. I am not sure how to create a direct script for this so be cautious.

Step 1: Create a Unique Key

---

• Open registry with “regedit” command on run window.
• Navigate to HKEY_CLASSES_ROOT\CLSID\. Then right click and create a new key with value as {FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}
• Now set the default value of this key to the folder name you want to use. Now your path will look like ( I will call this as parent key throughout the discussion) HKEY_CLASSES_ROOT\CLSID\{FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}

Step 2: Add Custom Icon to the folder

---

• Now create a sub key under parent key.
• Name it as “DefaultIcon”.
• Set the default value of this to the path of the icon image you want to use.
• If you dont specify your icon, system will take default icon.

Step 3: Adding attributes

---

• Under parent key create another key with name as “InprocServer32″
• Set the default value as “shell32.dll”
• Again at the same level create another folder as “ThreadingModel” and set its value as “Apartment”
• Same way create another key (under parent level) at the same level with structure as \Shell\My Folder\Command
• Set the default value here as “explorer /root,c:\Blog Data”
• This has to be same which you gave when you created the first key.

Step 4 Adding Handlers

---

• Under parent key, create another key as \ShellEx\PropertySheetHandlers\ {FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}
• Similar way another key is to added to parent key as “Shell Folder”
• In this right click and create new binary value called as “Attributes” with value as 00 00 00 00.

Step 5: Settings to place in My Computer

---

• Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
• Then to \CurrentVersion\Explorer\MyComputer\NameSpace\
• Add the parent key which in this case is {FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}

Thats it, You are done. Try this carefully and I am sure there wont be any problem. I missed the icon thing somehow, but will sure fix it. Till then if you find a fix do tell me.

How to fix the icon problem with system folder :

As per the icon issue, I had the same issue then realized it was just looking for the icon index at the end of the file path and is accomplished with a comma and your index number. If your using an .ico file the index will be 0 otherwise you’ll have to determine the index number if your using a dll or exe with multiple icons. i.e for an .ico file c:\path\Icon.ico
