a big fat thank you to all who responded! (list of good samaritans follows)
the suggestions worked and now i know a little more about what is going on :)

*short version:

Q1) how can one erase a file with a name like: .\usr\spool\mail\username ??
A1)#rm .\\usr\\spool\\mail\\username

Q2) what causes these files to be generated in the first place and how can i
    avoid their generation in the future??
A1) several suggestions:
        -`pine mailer creates files of this name form as lock files.
          it may be dying...'
        -`maybe one of your Mailtools was compiled with a M$-DOS option,
          that uses `\` instead of `/` as directory separator.'
        -`it looks like someone has a .pinerc with MS-DOS style pathnames.
          Pull up that user's .pinerc (or ask them to) and look those
          filenames.'
        -`do you have SoftPC installed'
        -`I'd have a long chat with Mr. Username about how heshe created them.
          These look like [gag] Windoze file names. This looks like somebody has
          ported some [gag] windoze shareware, and compiled it incorrectly.
          Spank them.' <-----(my personal favorite)
        -`Well, username 'username' owns the file, ask him.'

*long version with original questions at the top and complete responses
following:

hello

2 main questions:

i have found two files that i cannot seem to erase, even as root. they are
located in /usr/var/tmp and their long listing looks something like this:

1 -rw-rw-rw- 1 username 4 Oct 16 11:18 .\usr\spool\mail\username
1 -rw-rw-rw- 1 username 4 Oct 16 20:12 .\usr\a\username\mail\sent-mail

where username is the same for both.

1)How can i erase these files? (when #rm .\usr\spool\mail\username, i get a
  message like:
  rm: .usrspoolmailusername nonexistent)

2)How might i go about finding out what caused them and how to avoid it in the
  future?


*responses:

   The \ is a special character to the shell. Use \\ to get a single effect \
   rm .\\usr\\spool\\mail\\username
   or put the whole thing in single quotes.
   The pine mailer creates files of this name form as lock files. If they
   are left lying around, pine must be dying for some reason.

2. nelson_at_bv.com (Steve Nelson)
   easy one - rm .\\usr\\spool\\mail\\username (hise the \ with another \)
   also easy - keep all the pc users away from your system

3. alan_at_nabeth.cxo.dec.com
   Your first problem is that UNIX files names are separated by
        the forward slash character (/) not the back-slash character
        (\) as used by MicroSoft. The two are quite different. In
        fact UNIX systems typically use \ as an escape character to
        coerce the shell not to interpret the next character in any
        particular way.

        Your next problem is that /usr/spool/mail/username is the
        file used to store a user's incoming mail. Depending on
        the particular mail reader they use, it may also be the
        place where all that user's mail is kept. Your users will
        not appreciate having their mail removed. You would be
        wise to find out what a file is, before you try to remove
        it.

        The hier manual page may be very informative for what files
        are in different directories across the system.

4. Sylvain Robitaille <syl_at_alcor.concordia.ca>
   You need to escape the backslashes, because a backslash is a special
   character which usually means (to the shell) "take the next character
   literally." This should work:
   # rm .\\usr\\spool\\mail\\username
   The only cause I can think of is that someone at some point in time
   tried to make files using MS-DOS path conventions. In MS-DOS the
   backslash is the path separator, while in Unix it's the forward slash.
   Many users new to Unix, but familiar to DOS don't know this and try to
   form paths the wrong way.

5. "D. J. Vanecek" <djv_at_bedford.net>
   try rm .\\usr\\a\\username\\mail\\sent-mail
   or try rm *username* but be careful with that. "ls something" will expand
   the same as "rm something" so look at "ls something" first.
   I'd have a long chat with Mr. Username about how heshe created them
   These look like [gag] Windoze file names. This looks like somebody
   has ported some [gag] windoze shareware, and compiled it incorrectly.
   Spank them.

6. Pirie Hart <pirie_at_u.washington.edu>
   Try typing two (2) backslashes (\\) where one appears. The backslash
   character is magically, in that it escapes the meaning of other
   characters (such as *). Using two backslashes is interpreted to mean one
   REAL backslash.
   rm .\\usr\\spool\\mail\\username .\\usr\\a\\username\\mail\\sent-mail
   should do the trick. If not, try
   rm -i *username*
   The -i flag means to ask you before deleting each file.

7. harald hl_at_tekla.fi
   rm \\usr\\spool\\ ....
   Can't say for sure, but I'd guess it's some pc-like software, where /
   has been replaced
   with \. Do you have SoftPC installed

8. Trevor Schroeder <tschroed_at_cheetah.wsc.edu>
   You want to do rm .\\usr\\spool\\mail\\username
   Remember, the \ is the escape character, so rm .\usr\spool\mail\username is
   telling it to treat the u in usr, the s in spool, m in mail, and u in
   username as literal characters. You need to use \\ to tell it to treat the \
   as a literal character.
   It looks like someone has a .pinerc with MS-DOS style pathnames. Pull up
   that user's .pinerc (or ask them to) and look those filenames.

9. "Dave FitzPatrick" <fitzpatrick_at_quantic.com>
   Since the backslash "\" is a special character used to tell the shell not
   to interpret the special character that follows, but take it literally, try
   doubling them up:
   #rm .\\usr\\spool\\mail\\username

10.Isaac Kohen <koheni_at_voyager.bxscience.edu>
   rm -rf ./.\\usr\\a\\username\\mail\\sent-mail
   if that doesnt work, fire up bash and use * or a tab.
   Well, username 'username' owns the file, ask him.

11."Andrew A. Paine" <Andy_Paine_at_Earthling.net>
   if you truly typed the "rm" command as:
   rm .\usr\spool\mail\username
   then just turn the "slashes" around ("\" is for the PC)
   rm ./usr/spool/mail/username
   hope this is the correct soultion.

12.Ruediger Peusquens <rp_at_ikp.Uni-Koeln.DE>
   your
   # rm .\usr\spool\mail\username
   command does not work because \ is interpreted by your shell as an escape
   character to alter the meaning of the following character. Since u, s and m
   have no special meaning, the \ is simply skipped. (\ is useful to escape
   things like '(){};' or newline.)
   If you really mean \ use \\ since this will be interpreted as the literal \.
   To remove these weird files, you could either use
   # rm .\\usr\\spool\\mail\\username
   or just quote the argument
   # rm "\usr\spool\mail\username"
   That should do it.
   The filenames look like a complete M$-DOS file path. Maybe one of your
   Mailtools was compiled with a M$-DOS option, that uses `\` instead of `/` as
   directory separator.

13.Steve Wright (Sys Adm) <wright_at_cs.sc.edu>
   The shell uses the "\" as an escape character. It "quotes" the
   following one character. Try:
   rm .\\usr\\spool\\mail\\username



thanks again
