File by file checksums

I don't suppose a file-by-file on the fly update mechanism is in the works?

Our situation involves a large EXE, a hand full of DLLs, and about 6000 smallish files.

Sometimes we will have a customer manually patch one or two of those 6000 files (they're scripts in a proprietary language). This causes wyUpdate to first download about a 12MB patch, then discard that and download about 64MB for the entire enchilada.

If wyUpdate could do a checksum per file, then it could download and apply just those files which are rogue or out of date.

Maybe worth considering?

I think what you are suggesting is kind of an automatic version of the manual work-around suggested here: https://wyday.com/forum/t/954/less-strict-file-overwrites/

I don't know if that approach would work in your case though. You'd need to download less than 64MB but more than 12MB. However, the drawback is you can only specify the option project-wide, not for specific versions or even files.
