These $NtUninstall folders are created when you install a Microsoft Service Pack, a hot fix, or certain security updates. These folders contain the undo/uninstall information for the update you install. That means, you will be unable to remove an update in future, if you delete these folders. You may leave them there unless you need hard drive space. Each QXXXXXX represents an update from Microsoft. Can they be deleted?* Yes, they can be deleted and Fred Langa agrees. 10/16/2004
AVI stands for Audio Video Interleave.
Email etiquette should still be alive and well. Let me share a few pointers that you might care to pass along, privately, to those who may not be aware of the unspoken rules. Unless everybody knows everybody else in an email thread, it’s always best to use the BCC option. Believe me, every single email utility on the planet has a BCC option. But wait, there’s more you need to remember!* 11/12/2006

Fragmentation of files, especially heavily used files are one of the things I consider to slow down a computer system. Consider how the system handles files. You create a file on the hard drive. You then create more files. In the meantime, you delete one or two of those files. What happens is the system will sort of delete it. What it does is make the space available again for writing. It actually leaves the file data alone. The next time a file is written, that available space is then written . If the file uses all of the space and needs some more, the system looks to where some more available space is then writes it there, doing this till the complete file is written.*
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. The most important new feature of NTFS is the ability to encrypt files and folders to protect your sensitive data.*
NTFS Permissions - What Do They All Mean? Part I - NTFS permissions are used to secure folders and files. You can use them to control what other users can and cannot do with the resources stored on your computer. Before you attempt to configure any NTFS permissions, you need to have a good understanding of what each one means. This way you don’t inadvertently give another user the wrong permissions. The basic NTFS permissions are: Read, Read + Execute, Write, Modify, List Folder Contents, and Full Control. Each of these is described in more detail below.
How can I get a DOS floppy to read NTFS HDDs? NTFS Reader for DOS provides read access to NTFS drives from the MS DOS environment. It supports long filenames as well as compressed and fragmented files. NTFS Reader for DOS allows you to preview the files on NTFS and copy them from NTFS to FAT volumes or network drives. In order to use the software you need to copy the readntfs.exe file to a bootable floppy disk and boot from it.* 07/12/2003
In a network, promiscuous mode allows a network device to intercept and read each network packet that arrives in its entirety.*
Safe Mode is a special way for Windows to load when there is a system-critical problem that interferes with the normal operation of Windows. The purpose of Safe Mode is to allow you to troubleshoot Windows and try to determine what is causing it to not function correctly. Once you have corrected the problem, then you can reboot and Windows will load normally.* 04/05/2003
BIOS from A to Z - The Basic Input Output System - aka BIOS - resides in a small Flash EEPROM memory module on the motherboard. It's a form of read-only memory, but may be rewritten or programmed when the right tools and techniques are applied. During PC startup, the processor on the motherboard always executes the program stored in the BIOS as its first major maneuver.* 01/15/2006

There actually are several interrelated variables at play here, such as MTBF ("mean time between failures"), "expected write cycles," "data retention," and so on. If you can find the actual manufacturer of a flash drive (not necessarily the seller --- many consumer electronic devices are made by one company, then branded and sold by another...), you can look up the original specs, which often include detailed information.

Trish at Hardware Hell has a great description of this problem. The file appearing on your desktop with the filename ~, commonly known as a tilde, is a backup of your Windows Address Book. It is appearing as a result of the April 2003 Cumulative Patch for Outlook Express (330994). The patch is installed for Outlook Express 5.5 or 6 in response to a vulnerability that could allow an attacker to run code of the attacker’s choice on a user’s machine. To exploit the vulnerability, an attacker would have to be able to cause Windows to open a specially constructed MHTML URL, either on a web site or included in an HTML email message.
Unfortunately, there is a bug in the patch. Whenever you make a change in your Windows Address Book file (*.wab file), Windows makes a backup of this file. Generally this backup is called username.wa~ , however after the patch is installed the backup gets renamed to just ~ instead and saved in the directory where you start your Outlook Express. Most of the time, people start Outlook Express from a shortcut on their desktop, so the backup file gets placed there. This is how the tilde (~) file arrives on your desktop.* 04/15/2004
