Type
FOR %A IN ("c:\Documents And Settings\David Candy\My Documents\My Pictures\*.jpg") DO ren "%A" "p%~nA%~xA"
Will change all jpg files in a folder to p<original name>.jpg
The case of the A (as in %A or %~<letter>A) is important. FOR/IN/DO is uppercase to highlight the actual command syntax.
Replace path with your particular one. If you drag the titlebar icon of an open folder into the cmd window it will type it for you.
I would, if doing this for me, export file names and use Word's Search & Replace (it's similar to regexp in wildcard mode) to make a batch file. I've done this for at least 20 years (although with XEdit rather than Word).
He is a script that does Regexp on the file contents. You should be able to modify it to names.

Applies To: RegExp Object
Requirements
Version 2
Sets or returns the regular expression pattern being searched for.
object.Pattern [= "searchstring"]Arguments
object
Required. Always a RegExp object variable.
searchstring
Optional. Regular string expression being searched for. May include any of the regular expression characters defined in the table in the Settings section.
Settings
Special characters and sequences are used in writing patterns for regular expressions. The following table describes and gives an example of the characters and sequences that can be used.
Character Description
\ Marks the next character as either a special character or a literal. For example, "n" matches the character "n". "\n" matches a newline character. The sequence "\\" matches "\" and "\(" matches "(".
^ Matches the beginning of input.
$ Matches the end of input.
* Matches the preceding character zero or more times. For example, "zo*" matches either "z" or "zoo".
+ Matches the preceding character one or more times. For example, "zo+" matches "zoo" but not "z".
? Matches the preceding character zero or one time. For example, "a?ve?" matches the "ve" in "never".
. Matches any single character except a newline character.
(pattern) Matches pattern and remembers the match. The matched substring can be retrieved from the resulting Matches collection, using Item [0]...[n]. To match parentheses characters ( ), use "\(" or "\)".
x|y Matches either x or y. For example, "z|wood" matches "z" or "wood". "(z|w)oo" matches "zoo" or "wood".
{n} n is a nonnegative integer. Matches exactly n times. For example, "o{2}" does not match the "o" in "Bob," but matches the first two o's in "foooood".
{n,} n is a nonnegative integer. Matches at least n times. For example, "o{2,}" does not match the "o" in "Bob" and matches all the o's in "foooood." "o{1,}" is equivalent to "o+". "o{0,}" is equivalent to "o*".
{n,m} m and n are nonnegative integers. Matches at least n and at most m times. For example, "o{1,3}" matches the first three o's in "fooooood." "o{0,1}" is equivalent to "o?".
[xyz] A character set. Matches any one of the enclosed characters. For example, "[abc]" matches the "a" in "plain".
[^xyz] A negative character set. Matches any character not enclosed. For example, "[^abc]" matches the "p" in "plain".
[a-z] A range of characters. Matches any character in the specified range. For example, "[a-z]" matches any lowercase alphabetic character in the range "a" through "z".
[^m-z] A negative range characters. Matches any character not in the specified range. For example, "[m-z]" matches any character not in the range "m" through "z".
\b Matches a word boundary, that is, the position between a word and a space. For example, "er\b" matches the "er" in "never" but not the "er" in "verb".
\B Matches a non-word boundary. "ea*r\B" matches the "ear" in "never early".
\d Matches a digit character. Equivalent to [0-9].
\D Matches a non-digit character. Equivalent to [^0-9].
\f Matches a form-feed character.
\n Matches a newline character.
\r Matches a carriage return character.
\s Matches any white space including space, tab, form-feed, etc. Equivalent to "[ \f\n\r\t\v]".
\S Matches any nonwhite space character. Equivalent to "[^ \f\n\r\t\v]".
\t Matches a tab character.
\v Matches a vertical tab character.
\w Matches any word character including underscore. Equivalent to "[A-Za-z0-9_]".
\W Matches any non-word character. Equivalent to "[^A-Za-z0-9_]".
\num Matches num, where num is a positive integer. A reference back to remembered matches. For example, "(.)\1" matches two consecutive identical characters.
\n Matches n, where n is an octal escape value. Octal escape values must be 1, 2, or 3 digits long. For example, "\11" and "\011" both match a tab character. "\0011" is the equivalent of "\001" & "1". Octal escape values must not exceed 256. If they do, only the first two digits comprise the expression. Allows ASCII codes to be used in regular expressions.
\xn Matches n, where n is a hexadecimal escape value. Hexadecimal escape values must be exactly two digits long. For example, "\x41" matches "A". "\x041" is equivalent to "\x04" & "1". Allows ASCII codes to be used in regular expressions.

Thanks for the info, I've been trying to find a definite resource for
Windows version of Sed and it's been slow going.
This is what I want to achieve, as part of the original script, to
append something infront of the line..
sed -e s/\^&/\x20and\x20/ -e s/^./Test_/>>tmp.txt
sorta got what I wanted, however, I realised I need to deal with the
quote marks that you would get if the file has spaces in it. Thus,
"A&B.dwg" is to be conversted to "Test_A and B.dwg"
Right now I have "A&B.dwg" changing to Test_A and B.dwg"
If you can point me to a good resource/man page just for windows would
be great as well. Thanks. Putting quote marks in gives me syntax errors.
Escaping it will not work since the quote marks don't go in. \x20 means
spaces right?
Ok, I got this...
sed -e s/\^&/\x20and\x20/ -e s/[a-z,A-Z,0-9]/AP3D_^&/
That seems to work, but seemed like a rather in-elegant way of doing it.
Just curious as to how to deal with quote marks.
Thanks again for all your help.
