Your 1 Gig file is probably already compressed.. If it's a Video file, that is probably true. If it's the swap file, it's uncompressable because it could not efficiently store high-priority data without a large time overhead. You can buy a DVD ROM for next to nithing these days... perhaps to transfer the file to a DVD?

just use winzip zip it up then upload the files in winzip format

try zipping it. If it hangs and then fails, its because the file is too big to send.\n\nYou need to get a software that will compress the file like http://www.winzip.com

I would assume you got that on ebay from hong kong...they compress the drive to make it hold more and when you format it you take it back to its orriginal/correct size....you got screwed! I have not figuered out how to make it take 2 gigs again....I run a computer shop and I just had a customer with the same problem.\n\n-Doc-

wooooooooooow!!! u have created a compression s/w that reduces even 1 GB to 10 KB (u mentioned any file of any size) .. hehe are u sure that is a compression s/w or a s/w that creates a shortcut to the original file?? lolz... jus kiddin.. \n\nwell.. all i can say is.. start a company. \n\nCos what u have jus done is simply huge (that is.. if u have actually done it!!) \n\nGet some people (friends or family members would do good) along with u in that company. \n\nGive a press release, saying u have created so and so.. \n\nGet that thing Beta- tested by some popular people ..like editors of computer magazines , scholars etc. etc.\n\nStart a mssive ad campaign once u receive sufficient funds.\nand..\n\nVoila .. i have jus replied to the next bill gate's  \n\nquestion!! \n\n(the above statements hold true, if u have actually created one!!)\n\n; )

You can try Irfanview, it's free (ACDSee and Photoshop are fine too but they're not free) from http://www.irfanview.com/ \nIt also has a nice batch edit function so you can resize a whole folder at one go.\n\nBasically if you resize to 1024 on the longest side and save as JPG with 80% compression, it should give you a file in the one to two hundred kilobyte range.

You don't, you Un-Rar it first.\n\nuse WinRar - http://rarlabs.com/ to uncompress the file

there are a lot of compressing tools available in the internet. winzip, winrar, winace, etc all can compress files effectively.

try "www.filelodge.com"\n\nfree 500M space, i've been using it for awhile, works pretty darn good!\n\ngood luck!!!

If it isn't letting you it is because the file it too large.

Try Beamfile, send files up to 5GB in size for free, http://www.beamfile.com/  Note that beamfile must be installed on both computers, the one you send from and the one you are sending to.

Install WINRAR, then right click on the file you want to compress and there you will find compress with WINRAR, select that option. WINRAR will automatically compress the file in smaller bytes.

You need to load your file into your documents or where ever you load a file, then Zip the file.  The person you are sending the file to will not get the file that size without it being Ziped.  You might have to zip it twice.

Yes u are right. The only way to achieve that would be to use compression. However the amount by which data can be compressed is limited by the type of data and its characteristics. For example...\n\n1. A very large text document containing a novel can be compressed to around 20~30% of its original size. This compression however has to be lossless, i.e. the file recovered after decompression should have the same size, since u dont want ur text to have unwanted errors in it.\n\n2. Audio, specifically that within the human audible limits. Depending on the algorithm (eg. MPEG layer-3 or mp3, ogg-vorbis, WMA) used audio can be compressed to almost 10% of its original size (1CD 700mb to ~60MB). But these are lossy compression techniques, as in some audio data is lost but the differences is not perceptable to humans.\n\n3. Application - Typically installation files for programs. Pure binaries(eg. EXE files) can generally be compressed to about ~40% of their size and this compression needs to be lossless otherwise ur executable could get damaged. Most compression algorithms use various kinds of techniques to detect any errors introduced into the file using techniques like CRC.\n\n4. AV - audio+video, This is probably the case ur talking about in ur question. By use of appropriate software it is possible to compress an entire DVD movie (4.7GB) to a file of 700MB size which can fit on a single CD. This again uses lossy algorithms (DivX, xvid, WMV, MPEG4 etc.) using motion estimation (seeing which parts of a movie frame change) etc. techniques. (search google for auto-Gordian-Knot if you are interested in doing this)\n\nSo if u have seen someone compress 4.7GB onto a CD he was prolly doing it with a movie file. Movies downloaded from the internet are generally available in 700MB sized file so that they can conveniently fit on a CD.\n\nHope that helped.
