Same Filename handling

[mawosch]

After transfering some pictures I formated the Eye-Fi card. Then started again with shooting and transfering.
The camera gave pictures the same filename.
The problem was solved by the software to add a ".1" behind file extension. Thats a problem for normal file handling on computers.
Could you change the renaming behaviour to "DoubleFilename-A.jpg" or somthing like that?

Hm, yeah, that's true. I've set all my cameras to use sequential file names (ie. don't reset the counter when the card is emptied), so all my .1 files tend to be duplicates. I haven't really considered the use case where you want to keep both versions.

I'm a bit sceptical of messing about "inside" the file names; a trailing .1 is easy to identify and remove. foo123.jpg -> foo123-A.jpg / foo123-1.jpg / foo123+1.jpg can be much harder to identify unambigously (depending on the camera naming scheme, of course). But that may be too much paranoia. I'll have to think about it for a bit.

To solve your immediate problem, the sprintf() call in RIFEC::File::_link_file() would be the place to look. For your use case, I'm guessing you could change the single sprintf() to something like this (Note: this code is NOT TESTED):

my ($base, $ending) = split /\./, $destination_name, 2;
my $newbase = sprintf("%s+%d", $base, ++$tries);
$dst = join('.', $newbase, $ending);
