# Link to file in the parent folder

I have a folder, say `C:\example\paper` with a bib-file `C:\example\1.bib`.

I also have a tex file `C:\example\paper\main.tex` where I would like to put a link to `1.bib`. I can put the whole path, of course, but I wonder if there is a method to put link for a parent folder `C:\example` from its subfolder `C:\example\paper`?

On a Unix system `\bibliography{../1}` works; it should also on Windows. – egreg Sep 22 '11 at 9:39
Which Windows version and which filesystem (NTFS or FAT) are you using? – Martin Scharrer Sep 22 '11 at 9:40
I use Windows 7 with NTFS. @egreg, your example works, thanks. Will you write it as an answer? – Ilya Sep 22 '11 at 11:29

One can refer to the parent folder by `../` both on Unix systems and in Windows; therefore

``````\bibliography{../1}
``````

will work for the bibliography file `1.bib` that resides in the parent folder.

Note that paths on Windows are expressed with `\`, but for TeX related programs the slash `/` works in its place and is of course preferable.
