生成的pdf文件可不可以存放在一个指定的文件夹内？

这里有一个答案： [https://tex.stackexchange.com/questions/7265/need-aux-file-in-separate-folder](https://tex.stackexchange.com/questions/7265/need-aux-file-in-separate-folder "https://tex.stackexchange.com/questions/7265/need-aux-file-in-separate-folder") > With MiKTeX and TeX Live you can use --output-directory=dir. This will put all output files including .log and .pdf/.dvi in this directory (and append it to the search path so that auxiliary files are found). > In MiKTeX you can additionally set --aux-directory=dir which will put only the auxiliary files in this directory. 经测试，TeXLive没有问题，MiKTeX我没有，没有进行测试。

好像是加 `-output-directory` 选项，例如 ``` pdflatex -output-directory=dirname filename.tex ```

可以设置输出目录，但是没必要，给自己带来麻烦。最后清除辅助文件也不是没有快捷的方式。
