It seems to stay in "." and already descending into it is not performed. Even 
if it would do this one step, it would include the directories in this 
directory. But as he shouldn't descend into them, they will be empty in the 
archive. E.g. something like:

 File1
 File2
 File3
 Subdir

and Subdir is a directory. I would assume that you want the plain files in the 
particular directory only. I don't know whether it's feasible for your case, 
but a `find` could help:

$ find "/tmp/fld 1/" -maxdepth 1 -type f \! -name "files.tar" -execdir tar cf 
"/tmp/fld 1/files.tar" {} +

Files will have the names:

./File1
./File2
./File3

though, but it shouldn't hurt.
