Proto-Germanic: *fīlō, *feilō
Meaning: file
Old Norse: { ɵēl }
Old English: { fēol }, fīl
English: file
Old Saxon: fīla
Middle Dutch: vīle
Dutch: vijl
Middle Low German: vīle
Old High German: fīla (fīhala um 800 -- contamination with bīhal 'Beil', selon Fraenkel)
Middle High German: vīle st. f.
German: Feile f.
Comments: Another possible reconstruction (taking into account the OHG fīhala) is *finx(i)lō; in this case the Balto-Slavic forms should be regarded as borrowed from Germanic -- but the Baltic diphthong is unexplained.
