# Tagging questions about .aux, .log, .bbl, & similar files

Two tags, and talk about the non-input/output files used by *TeX*. I propose that we have one, , with two synonyms, because:

• The Texbook talks, I think, only of input, log, auxiliary, and dvi files. Thus talk of temporary files is not classical.
• Besides also not being classical, "aux-files" suggests that we are talking only of files with a .aux extension, while the Texbook uses auxiliary files generally for files output to for later input from by the Tex engine, including with the .tex extension.

A minor issue: things like log files and .bbl files may commonly be referred to as auxiliary files, but they are, respectively, not input to and not output from the Tex engine, so they don't fit the above definition.

I've tagged the following , which did not have related tags beforehand:

I don't have enough upvotes in any of these tags to propose or vote on these tag synonyms, and I think few enough people have that it would need moderator action to realise my suggestion. So, should we merge the tags?

• I agree that these tags should be merged. Questions about bbl files should imo be tagged {bibliographies}. – Caramdir Jan 31 '11 at 22:53
• +1 for merge to {auxiliary-files}. – Martin Scharrer Feb 1 '11 at 8:38
