But you are not new to e-mails. So, please don't specify a stupid
subject line, but a sensible one. (OK, the rest of this message's body
is unspecific as well, hence the subject might be quite sensible in a
way, tough.)

The working directory is the one you are starting R in, or what you have
set with setwd(). It's not a good idea to create a working directory
within the library section. Specifying the full path should always work.

What you did wrong is:
- not reading the manual "An Introduction to R" carefully
- not reading the manual "R Data Import/Export"
- beeing to unspecific. After having read the manuals and help pages,
you may ask a specific question, but including error messages and code
you used (we cannot help if we cannot look at your mistakes).

Yes. Exporting Data (including ASCII formats) is also covered in the "R
Data Import/Export" manual.
