"Resume if smaller, warn if larger, skip if same size"

[Chris]

When catching up, restaring a big tree of files. the most
obvious action for "default file exists action" in the settings
dialog would be,
"Resume if smaller, warn if larger, skip if same size".
That option doesn't exist, and it really should.
When set to "Resume", it Resumes ALL files that already exist,
even though 99 of them are complete and the same size.
Filezilla client says REST (restart) and then RETR (retrieve)
looking for the 350,000,000th byte of a file of
350,000,000 bytes long. The FTP server sends back "0 bytes"
(the rest of the file). Success. Next file. Oh, it exists
too... same. You could die of old age before it gets back
to work on transfering a 4GB tree of 50,000 small files.
So you are forced to choose "Skip" and then manually figure
out which 100 files came up short due to all those internet
interuptions.

Using latest Filezilla Client 3.1.5 and latest
Serv-U Server 7.2. Advocate for XCRC and XMD5 commands too.
