Compression Test

COMPRESSION TECHNIQUE TEST

Recently did a compressing test, had a folder with lot of text file.

The size of the folder was 10.0 MB

I made a TAR of it, it was 8.8MB and then i compressed it using GZip and it was compressed to 4.5MB, pretty impressive.

Then next i used bz2 and results were better 4.3 MB cool.

But then i tried compressing into 7z Format and can't resist myself writing this post here.

It was merely 2.3 MB wow! i mean too good. But directly converting the folder to 7z was making it around 4.6 MB but after TAR, 7Z won the race.

Short summary:

Real Folder Size 10.0MB

TAR 8.80MB

TAR.GZ 4.50MB

TAR.BZ2 4.30MB

7Z 2.30MB

(though it was done after TAR, extension was still 7z but it extracts to TAR).

Test done using 7Z open source software, on windows 7 ultimate 32BIT.

Setting of compression were ULTRA

( PS: zip stands no where)
