What is a zipped folder?

Today a young lady asked me what a zipped file is and for those that may not know here is my explanation – I believe you are referring to a zipped folder. It compresses or compacts multiple files into one so you can send those files more conveniently over the internet. Example, Instead of sending 10 photos as 10 attachments you could zip them in a folder and now you are only sending 1 file instead of 10 individual files or attachments. The recipient unzips the folder and has access to those 10 photos or documents inside.

zipped folder

Microsoft’s definition of a zipped folder is.

Folders that are compressed using the Compressed (zipped) Folders feature use less drive space and can be transferred to other computers more quickly. You can work with a compressed folder and the files or programs it contains just as you would an uncompressed folder.

Once you have created a compressed folder (identified by the zipper on the folder icon), you can compress files, programs, or other folders by dragging them to it. You can open files directly from compressed folders, or you can extract files before opening them.

You can run some programs directly from zipped compressed folders, without decompressing them. However, to run programs that are dependent on other files, you must first extract them.

Compressed folders can be moved to any drive or folder on your computer. You can also share zipped compressed folders with other users, even if they use a different file compression program.

You can protect zipped compressed folders with a password. This protects your data if you save it in a shared network folder, attach it to an e-mail message, or move it between work and home on floppy disks.

Windows also offers another way to compress folders if your drive is formatted as NTFS: NTFS file compression. However, NTFS file compression is significantly different from compressing files with Compressed (zipped) Folders.

No extents were found for the plex

No extents were found for the plex

Yesterday a friend asked me to help him troubleshoot a problem he was having when he was attempting to setup RAID 1 also known as mirroring.  He wanted to mirror the Operating System hard drive to a second hard drive and told me he cant get the System Reserved partition mirrored.

I asked him to show me exactly how he was attempting to perform this task and as I suspected he mirrored the (Boot, Page, Crash Dump) partition which is most commonly known as the C: drive first.

Next he would attempt to mirror the (system Reserved Partition) which by default is 100 MB in physical size.

I remember when I tried this several years ago myself  I encountered the same problem and with some experimenting I figured out how to do it and below are the steps.

First if you already created a mirror in windows vista or windows 7 go ahead and break it.

Now back to square one here are the steps to mirroring windows vista or windows 7.

Step 1
Assuming you already know how to mirror drives. (Software Mirroring or Software RAID 1)
IF YOU DON’T KNOW HOW TO MIRROR DRIVES it is in your best interest to ask somebody that knows how to mirror drives to walk you through the process or better yet do it with you so you learn without screwing up.

Step 2
Mirror the (System Reserved) partition first.

After this completes, reboot the computer then mirror the C: drive then after the Resynching completes reboot again.

Now both partitions will be mirrored.

Final thought on this.
What does the error No extents were found for the plex mean?
I still don’t know.

What is the difference between USB and Ethernet?

USB also called Universal Serial Bus presently comes in 2 versions.
USB 2.0 and USB 3.0

USB 2.0 transmits data at 60 megabytes per second.
USB 3.0 transmits data at 400 megabytes per second.

Physical distance is stated at 10ft maximum according to various text books however in the real world I have successfully used USB cables exceeding 25 ft without any problems.

USB can also be used to transmit power which is how a USB hub, USB mouse or other USB device lights up when it is plugged into a powered USB port. USB can transfer and transmit Data and Power.

USB works well with printers, keyboards, digital cameras, camcorders, external ROM – drives such as CD and DVD burners, external hard drives and other devices that support USB that are physically close to the USB port / HUB or computer.

Ethernet on the other hand does not transmit power and only transmits data.
Ethernet presently comes in 2 versions.
Category 5 and Category 6.

Category 5 transmits data at 100 megabytes per second.
Category 6 transmits data at 1000 megabytes per second.

Physical distance is usually around 100 yards / 300 ft however I have seen Ethernet cable runs that exceed this distance and perform well. Generally if your Ethernet run is more than 300 ft you may or may not need a (Ethernet repeater – switch) which will vary from physical situation to situation.

Ethernet is used for networking computers, routers, switches, networked printers and other networked devices.

What is the difference between USB 2.0 vs USB 3.0

QUESTION:
What is the difference between USB 2.0 and USB 3.0?

ANSWER:
USB 2.0 is capable of data transfer speeds of 480Mbps which is a little shy of 0.5 Gigabits per second.
USB 3.0 is capable of data transfer speeds of 5GBPS which is 10 times faster than USB 2.0.

Simply put without getting into a bunch of technical jargon. This means transferring data would be noticeably faster with USB 3.0 when compared to USB 2.0. When we say transferring data we mean between a computer to a USB hard drive or thumb drive. This has absolutely nothing to do with computer networking data transfer speeds. Keep in mind your computer will have to support USB 3.0 in order for you to benefit from a USB 3.0 devise such as a USB 3.0 hard drive or USB thumb drive.

What are the email attachment size limits for yahoo, hotmail, gmail and AOL ?

QUESTION:
Do you know what the email attachment size limit is for Hotmail, Yahoo, and Gmail, and AOL?

ANSWER:
Hotmail is 10MB
Yahoo is 20MB
Gmail is 20MB
AOL is 25MB

You can send and receive emails up top the above size limits which included the email message itself, header and email attachments. If the email exceed the thresholds above then you will need to compress the email or split the attachments into smaller emails. If you send a large email attachment that is under the threshold and you receive a bounce-back error message this most likely means that the recipient’s email provider or server has a smaller limit then you may want to consider transferring the attachments another way then email. Traditionally Email was not really designed to send and receive huge attachments. That’s what FTP also known as File Transfer Protocol is good for. If you do not know how to FTP files then you may want to ask your in house network administrator to help you should you have one. or another good alternative that is real easy to use is a file transfer service provider called You Send It. Whats nice is they offer free plans that are good for individuals and small businesses.

Memory limits for the different versions of the Microsoft Windows 7 Operating System

QUESTION:
How much memory can you use with Microsoft Windows 7 ?

ANSWER:
First without getting into a bunch of technical detail here is a straight to the point breakdown of how much memory is supported with the different flavors / versions of Microsoft 7.

Microsoft offers it’s Windows 7 operating system in six different versions.

First you need to know that the maximum RAM – memory limit for 32-bit Windows 7 operating system editions is 4GB.
Which is more then enough for the average user.

For power users, special application computers, etc 4 GB of memory may not be enough.

The 64 bit editions of Microsoft Windows 7 support the following amounts of memory.

Microsoft starter Edition: 8GB
Microsoft Home Basic Edition: 8GB
Microsoft Home Premium: 16GB
Microsoft Professional : 192GB
Microsoft Enterprise: 192GB
Microsoft Ultimate: 192GB

These memory limits are similar to those with Microsoft Vista flavors / editions.

Which version is right for you?
We will get to that in another article….:)
