Re: Export entire changed files for zip patch

Hi Nathan,

I take your point - it probably wouldn't be such a bad thing to package
up the entire revision. My thinking was that I didn't want to re-upload
things that really, really haven't changed - in particular the images
associated with the site. The site I'm currently working on is ~52Mb
with ~6,000 files so without an uber-uplink that's frustrating
(especially the ftp chatter for lots of small files). I could transfer
it to the site compressed (~13Mb) and decompress using a web file
manager but that'd just be another step with another login.

As it stands my recent changed files from the previous revision is ~2Mb
uncompressed and only 25 files. This makes it far more manageable to
distribute and upload.

Cheers,

Scott
