Description

I request a new feature of being able to calculate an
MD5 checksum, or some other adequate checksum, on both
local and remote files for file equality comparison.
Remote files would need to be downloaded to a temporary
location to compute the checksum. (or calculated 'on
the fly' without actual physical storage locally)
So you should be able to select one or more files and
choose "Compute Checksum", and the values would be
displayed as one of the optional columns for those files.
The values would need to be erased if the file is
re-uploaded or re-downloaded.
It would be nice if the values were remembered as long
as the directory wasn't changed, but they are really
only needed for a moment's comparison and can then be
forgotten.
Optionally, or additionally, it would be nice to be
able to select two files, one local and one remote, or
perhaps even two local, or two remote, and choose a
"Check Equality" button that computes the checksum of
each file and tells you if the files are equal, or not.
If you could select more than one file locally and
remotely and have all of the equally named files
compared, that would be nice, too.

Feature request, moving to appropriate tracker.

This MD5 checksum comparison request might be easy to do with a Content-MD5 header field on the server and checksumming on the client site.

Implementing XCRC is probably the right way to go.
