What bug are you suggesting? There's a directory named "1000" and it
contains a file called "1000.zip". That's all very clear by what's
shown here. Perhaps this situation arose earlier in your confusion
about shell glob characters, find and whatnot.

Thanks for the hint with -follow it worked, but the directory 1000 is
not a symbolic link as you can see
$ find . -name 1000\* -follow
$ ls -ld 1000
drwxr-xr-x 2 f.braunb unknown 0 Jan 31 08:33 1000
$ ls -l 1000*
-rw-r--r-- 1 f.braunb unknown 162114808 Jan 30 14:57 1000.zip
-rw-r--r-- 1 f.braunb unknown 162114808 Jan 31 08:33 1000.zip
Could this be a bug?
Sometimes in circumstances like this, confusion can be reduced by using
the "-i" option to ls. This will cause ls to include the "inode number"
in its output. (This is not quite the same thing in Cygwin as in real
Unix file systems, but it's there and serves the purpose of this hint.)
Distinct files that are otherwise identical and, beyond their full path
names, indistinguishable (same name, size, modes, owners, etc.) will
have different inode numbers. Likewise, hard links (possible with NTFS
but not FATn) will have identical inode numbers even if their names are
different. However, given that hard links are just multiple names for
the same file, it's impossible to have any other file attribute differ
between two hard links to the same file.
One last wrinkle to note is that if you attempt to create a hard link
on a FAT file system volume, Cygwin will copy the file for you. That's
its best-effort attempt to comply with a request that cannot literally
be fulfilled but which is nonetheless required by POSIX compliance.
(I'm presuming a bit here as to motivation for the fallback behavior
for hard linking on FAT file systems.)
