Hi everyone,

The web design company I have hired to build my website have mistakenly overwritten some of the pages and we would now like to go back to these pages with this particular earlier code and I just wondered if anyone knew the best way to recover overwritten files from your computer?

Any advice will be gratefully received.

there's some software that can, sometimes, if you're lucky, do that, by reading the disk as a physical block device rather than an operating system disk device.
No guarantees of course, if something else has been written since in the physical location of the original it's gone forever.

Your best bet is to hope there are backups...
