Upi:Difference between FAT and NTFS

FAT (FAT16 and FAT32) and NTFS are two methods for storing data on a hard drive. The hard drive has to either be formatted using one or the other or can be converted from one to the other (usually FAT to NTFS) using a system tool

NTFS is a high-performance and self-healing file system proprietary to Windows XP 2000 NT which supports file-level security compression and auditing. It also supports large volumes and powerful storage solution such as RAID.

"Redundant Array of Independent Disks." RAID is a method of storing data on multiple hard disks. When disks are arranged in a RAID configuration, the computer sees them all as one large disk. However, they operate much more efficiently than a single hard drive. Since the data is spread out over multiple disks, the reading and writing operations can take place on multiple disks at once. The benefits of RAID come from a technique called "striping," which splits up the stored data among the available drives.
The most important new feature of NTFS is the ability to encrypt files and folders to protect your sensitive data

Differences of FAT and NTFS

NTFS stands for new technology file system or network technology file system. In NTSF partition size can be of 2 TB or more. and file size can be 16 TB. file/folder encryption is done. and it supports file name character upto 255.

FAT32 stands for File allocation table. in FAT32 partition size can be Upto 2 TB. and file size can be 4 GB. file/folder encryption is not possible in FAT32. and it supports file name character upto 8.3.

fat32 can be converted into ntfs without losing any data using command:
convert [drive letter]:/fs:ntfs

ntfs can not be converted into fat32 without losing data.

upi:No Folder Options in Tools Menu

Many people find that in their windows Tools -> Folder Options is not visible, they also can't access it from the Control Panel.

1.) You can enable Folder Options by simply editing the Windows Registry! Just type regedit in RUN dialog box and it'll open Registry Editor, now goto following keys:

Code:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

And in right-side pane, check whether a DWORD value named NoFolderOptions exists or not? If it exists then either change its value to 0 or delete it.

2.) But sometimes u can find that regedit is also disabled, when u'll try to open regedit or run the downloaded reg file, u'll get error:

Quote:
Registry Editor has been disabled by administrator.
Its a symptom of "RONTOKBRO" Trojan!

3.) If its not a virus problem and someone disabled Registry Editor in ur system, then u can enable it again by following any of following methods:


a.) Type gpedit.msc in RUN dialog box and goto:

User Configuration -> Administrative Templates -> System

in right-side pane, set "Prevent access to Registry editing tools" to either Not Configured or Disabled.

b.) Just type following in RUN dialog box and press :

Code:

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f


Now after enabling Registry Editor, u can enable Folder Options again by using 1st or 2nd step

4. Close all other browser windows.

Important: Temporarily disable your anti-virus, real-time protection before performing a scan. They can interfere with combofix or remove some of its embedded files which may cause “unpredictable results”.
