Question My files are growing!!!!


My files get larger everytime I copy them!? Why?
I got a zip file I copyed from one location to another. The file didnt work so I copyed it again. And then I noticed that the filesize was geting larger. How can this be?

You mean the actual file itself is growing in size or the filesystem usage?

Are you compressing the file every time you copy it? If you compress an already compressed file, it will often (usually) grow bigger instead of smaller. Or so I've heard....

If that's the worst you do, count yourself lucky! I do worse than that almost every time I sit myself down at my computer. Using Linux is a humbling experience for ME.

jonr,

Yes, it is true. a compressed compressed compressed file will definately grow bigger. Once it can only get so small, the file must also retain the info on how the compression algorithm is stored.

simply gzip a gzip file and then gzip the gzipped gzipped file again.

Sounds like "Alice in Wonderland," doesn't it?

Thanks for the confirmation. I was pretty sure that was what happened.

Maybe the inventor of compression was hitting on the
catapillar's pipe
