While documenting our software we realized nobody here knows how the separator inside a path is called.
/some/linux/path/

C:\some\windows\path\

C:¥some¥windows¥path¥injapan¥

Our initial intuition told us, that we could use either "Pfadtrennzeichen" or "Verzeichnistrennzeichen", but thinking and talking about it we came to the conclusion if interpreted rigorously those mean "the character separating whole paths from each other". (e.g. ;
in /path/one/;/path/two/
)
Looking into the Wikipedia page about paths, the authors sidestepped this problem elegantly by not mentioning the differences between Linux and Windows paths. Looking into this Wikipedia page about slashes the used term is "Trennzeichen" but without specifying what exactly is separated, since the context is given by the article.
To be honest I'm not convinced the English term "path separator" we are using in our english documentations is 100% correct either, since there seems to be some confusion about it too: Question about Java pathSeparator vs separator but that is a question for another time.

of the separator are "Schrägstrich" and "Umgekehrter Schrägstrich" according to the Wikipedia page and my personal experience (also native speaker). Depending on what industry you work in, you will have to use the good old German terms.
