Hi,

I have Linux web hosting plan, and the space available to me is just 500 MB, I have 4 websites, well, I know, that 500 MB space is sufficient for these sites, but, can anybody, tell me how to save space, so that if in a future any addition to these websites is done, I may not be short of disk space.

Regards,

Well, I think you need to properly manage disk space by removing old content or unnecessary files & pages. Also it is good policy to use images/files modified for web, using compression tools and compressed formats.
