It is Amazing to say compress ur 1GB data/move into 10MB. Really it is possible with the KGB Freeware (Open source) software. U can Down load the software from http://kgbarchiver.net/?page=download and fallow the following the steps.
Its damn simple..Heres the procedure.. U can compress that data in two formats..1) KGB format 2) ZIP format ..Everyone knows the ZIP format..I tell u which is better & why..If u do it in KGB format it takes 5-6 hours on a 256 mb RAM, to compress 1 GB data/movie in less than 10 MB , but (this is not which i prefer) coz to decompress u take the same time.. So its useless..& u need KGB archiver only only for this format to decompress..But if u do it in ZIP format it takes 6-7 hours on a 256 MB ram, but i tell u its worth coz WINRAR & WINZIP both can decompress it in seconds.. OK now its clear that which format to use & which is better..Now we'll go how to use that software..Run the application>> It asks for which file u wanna compress>> select the file>> after u select>> U get two options in which format u want to compress it>> select ZIP format ( I prefer ) >> and then set compression level to maximum (maximum the compression level , small the size of it will be compressed)>> Just ignore the time given below it coz its just useless....... There is option that u can auto shutdown ur computer after the compression is over..SO u can got school/college/office & keep it to get compressed.. I do the same..
