BibTeX, biblatex and biber ⇒ Blank Spaces in Path to BibTeX Database Files

[beethovengg]

hello LaTeX and BibTeX experts,

suppose i have two bibliography database files, E:/Folder1/database1.bib and E:/Folder2/database2.bib (there are no spaces between ``Folder" and ``1", there are no spaces between ``database" and ``1", there are no spaces between ``Folder" and ``2", there are no spaces between ``database" and ``2"). then, i find no problem calling the following:

\bibliography{E:/Folder1/database1,E:/Folder2/database2}

However, when there are ``spaces" in the folder name and/or in the database filename such as ``Folder 1" and ``database 1", then calling the following

\bibliography{E:/Folder 1/database 1,E:/Folder2/database2}

does not work for database 1 (citations within this database does not work).

If I try the following,

\bibliography{"E:/Folder 1/database 1",E:/Folder2/database2}

still this does not work for database 1.

May i seek help on calling Bibtex database files when there are spaces in the filenames? Or is it really a constraint that the bibtex database filename must have no spaces in it (i.e., contains only one word)? (i'm not inclined to think so)

thank you for your kind help
