Compress and uncompress files (zip files)

[DonnaB]

Now that's a nice visual tutorial for those who don't know how to send large files via email. I've had many people try to send me manuals yet couldn't due to their size. Very nice abs!

No problem...zip files have been a mystery too many for a long time

They are not complex...when understood and are a great computer tool

Very nice little video, and simple to understand!

Some files cannot be read by windows tho, and this is where the likes of 7zip come in. (free)

However, you know how inquisitive i am. How, exactly, can you reduce the size of he file without losing quality in the origional document?

Can't be done? Thats what i thought too, till i saw this. (P.S i LOVE this website. This website saved me £200 in locksmith fees!)

MrDarn Just for the record, it is not possible to size a jpg file larger than its original size without losing sharpness

But you can email the original jpg file in larger or smaller "resolutions"
1024 × 768 ... 800x 600 are different sizes (resolutions) for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels....the pixels are square and good quality
(You need to be careful with images as some heights and widths are rectangular and thus distorted)

This example would normally be spoken as "ten twenty-four by seven sixty-eight" or "ten twenty-four by seven six eight".

Hope that helps a bit

Since WinXP zip files can be opened by Windows

You are correct 7Zip is often needed for other different file types...I use 7Zip too

There are whole books and thousands of pages and pages on the INTERNET full of opinions on what is the best way to sharpen images. Programs that sharpen quality are like Photo Shop ($$$ pay) and GIMP (free)....there are others too How you sharpen the image depends on what you want to do with it after it's been up sized and how much you enlarged it There are so many variables especially if you enlarge a jpg....quality will need to be sharpened, but to email a jpg ...simple pick a resolution size to send it....the quality will be the same as the originally jpg file to the users eye

You really can't enlarge a picture without it becoming pixelated. Its easy to make them smaller, but not bigger. Wish I had better news for you!....but, the good news is sending email or viewing jpg files on a computer, can be done via zip without noticeable differences (technically, there is some unnoticeable quality lose after zipping)
