%n   : the selection number
   %np  : the selection number relative to the file path
          for example:
          File               %n        %np <----
          \Dir1\Img1.jpg     001       001 <--------
          \Dir1\Img2.jpg     002       002

          \Dir2\Img3.jpg     003       001 <--------
          \Dir2\Img4.jpg     004       002

So for example use

Expression: %b %np.%e

          \Dir1\Img001.jpg <--------
          \Dir1\Img002.jpg 

          \Dir2\Img001.jpg <--------
          \Dir2\Img002.jpg

Info from the help:

   %b   : the "base" name          (ie for "autoexec.bat" it is "autoexec")
   %np  : the selection number relative to the file path
   %e   : the name extension          (ie for "autoexec.bat" it is "bat")

                                             Siren is a freeware file renaming program
                                               - portable, highly flexible, powerfully -
                                          If it's looking tricky it's easy to rename with Siren.
                                          http://www.scarabee-software.net/en/siren.html

Use the expression :
Img_%N.%e or Img_%N{3}.%e

The following expression will work with any filename which has # at end of the name:
%b(s/(\d+$)//i)%N{3,,-1}.%e

Example:
anyfilename-2.jpg                =>  anyfilename-002.jpg
Any.filename34.jpg              =>  Any.filename034.jpg
Any17_filename_12.jpg       =>  Any17_filename_012.jpg

Obviously use any desired values in the %N expression.

To add a separator, put desired character between the RegEx  & the %N:
%b(s/(\d+$)//i)_%N{3,,-1}.%e
%b(s/(\d+$)//i)-%N{3,,-1}.%e

To remove a separator, put undesired separator before the \d:
%b(s/(_\d+$)//i)%N{3,,-1}.%e
%b(s/(-\d+$)//i)%N{3,,-1}.%e

To change the separator, do both (note: there is a space between _ and ~)
%b(s/([-_ ~.]\d+$)//i)_%N{4,,-1}.%e
ie:
Filename-1.jpg         =>   Filename_0001.jpg 
Filename_20.jpg       =>  Filename_0020.jpg
Filename 300.jpg      =>  Filename_0300.jpg
Filename~4000.jpg   =>  Filename_4000.jpg
Filename.050.jpg      =>  Filename_0050.jpg

%b(s/(.*?)_(.*)_12[23](.*$)/\2/i).%e

If the random # prefix has already been removed, the following will remove just the suffix:

%b(s/(.*)_12[23](.*$)/\1/i).%e

This works even when the filename includes _123 but breaks down if one of the 3 digit random #'s after the _123 is another _123. In that case just run the file again with the second expression.

Examples:
27053_1962_Calendar_12.Janet_Pilgrim_123_1175lo_460_345.jpg  =>  1962_Calendar_12.Janet_Pilgrim.jpg
0220965_1964-04_123_PMs_Revisited.1956_123_1041lo.jpg  =>  1964-04_123_PMs_Revisited.1956.jpg

But:
89930_cal._1960_05.Janet_Pilgrim_123_835lo_123_456.jpg  =>  cal._1960_05.Janet_Pilgrim_123_835lo.jpg
Run again with 2nd expression:
cal._1960_05.Janet_Pilgrim_123_835lo.jpg  =>  cal._1960_05.Janet_Pilgrim.jpg

Hope someone else finds this useful!

btw nice program

First of all thank you for the Siren Program.....
My question is about how to sort the File List.
Let's say I have three files in the file list named 1, 2 and 3.
The order in which I want to rename them is 3,1,2.
How do I manage this within Siren?
Thanks in advance.......

Is there a way to use mathematical operators like addition?

I want to rename

t00.tif --> t24.tif
t01.tif --> t25.tif
t02.tif --> t26.tif
t03.tif --> t27.tif
etc.

Is there a way to do that with Siren?

Thanks,
Tom

A: That is easy to do with Siren renamer:

Download and unpack the new beta of version 3 of Siren, now for both Windows Win32 and GNU/Linux,
from http://scarabee-software.net/forum/viewtopic.php?id=273  (or newer)

There you have the new expression elements:

Random number (%Rn),
alpha (%Ra)
and string (%Rs).

They all can be followed by "{<length>}"

(With Siren renamer v2 you have %R only (a four digits pseudo random number) )

So use as
EXPRESSION: %Rn

to get eight digits like
26910045
63646763
91475005

Or EXPRESSION: %Ra
to get eight upper or lower case chars like
ZwAPQRvL
wigrOvjc
DZXxpHqL

Or EXPRESSION: %Rs
to get eight upper or lower case chars or digits like
gcVQq7sZ
e2nsaw4E
e2fgWq21

Use EXPRESSION: %Rs.%Ra{3}
to get eight sign, an dot, followed by three chars like:
hxSPRW0M.ozI
8AWyfdiF.IHw
sAfmWR9Y.WCv

You can use the default parameters like u,U,l and L to change the case
to get always lower case "extensions": %Rs.%lRa{3}
RRxJ7Gc2.fkb
MY20H08X.mmk
at2jVEr6.qby

And then you can use this {...} length and the case modifier to the "name part" too: %uRs{12}.%lRa{3}
DYXSVVR0WSSM.jue
MHZ26YJKS8TA.aoj
GNAKYOO9TJXQ.jzu

Examples:

Maybe you want to add an randomized number in front of your MP3 files to make an random playlist?
%Rn{3} - %f

-

You can also combine this elements like e.g.: %Ra%Rn{2}
MxtYVOxh18
xopVYBjZ61
hzUbDntO60
to generate passwords ;-)

-

To add four random lower case  chars at  the end of the original file name, right before the dot of the
extension, (maybe before joining differend sub-folders to not overwrite same file names) use: %b %lRa{4}.*

Press the F1-key while you are in Siren to read more about.
Enjoy Siren,  No installation needed, unzip and run. Siren stores it settings into an ini file, not in the Registry.

Q: I want to replace an hyphen/dash/minus "-" by an plus sign "+". But only the second one!

  FROM:
     SpongeBob, Schwammkopf, S01E17 - Die Schatzsuche - Bus verpasst.ext
     SpongeBob, Schwammkopf, S01E18 - Texas - Energisch.ext
     SpongeBob, Schwammkopf, S01E19 - Aprilscherze - Ein göttlicher Burger.ext
  TO:

     SpongeBob, Schwammkopf, S01E18 - Texas + Energisch.ext
     SpongeBob, Schwammkopf, S01E19 - Aprilscherze + Ein göttlicher Burger.ext

A:  That's looking difficult but can be done easy with Siren

         To read what we do now press F1 in Siren
         and go to "Expression > Modifiers > String modification : "( )" "
         and there a little bit down to
           
           String replacement
                      The usage is near of the standard "replace" : ( "s1", "s2", s, n, c )
                      s1     string to replace
                      s2     replacement string (If it is not specified, the string to replace is deleted)
                      s       starting occurrence (If negative, it is relative to the end of the string)
                      n       number of replacements to do (If negative, all remaining occurrences are treated)
                      c       number indicating if the search is case sensitive : 0 (zero) for no, any other value for yes

To make it easy we use the Siren variable %f which will work on the whole file name incl. the extension.
(To work on the base name only use %b and %e for the extension. But you may need this only to replace all dots but the last.)

So use the
EXPRESSION: %f

and press the Enter-key so the NewName is computed.
You will see the same as in the CurrentName column because %f just is an placeholder for the filename incl. extension.
No modification is done right now.

--

Now we utilize  the "String replacement" modifier ( "s1", "s2", s, n, c )  to the %f parameter.
First we start simple and just do the basics: %f("find string", "replacement string")

Or in our case:
EXPRESSION: %f("-", "+")

and press the Enter-key so the NewName is computed.

You will see as NewName something like:
SpongeBob, Schwammkopf, S01E17 + Die Schatzsuche + Bus verpasst.ext

As you may have noticed this has replaced all both hyphens "-" in that name to an plus sign "+"

--

So let use use now one of the advanced parameters ",s ,n ,c" of this expression element :

EXPRESSION: %f("-", "+", 2)

and press the Enter-key so the NewName is computed.

You will see as NewName something like:
SpongeBob, Schwammkopf, S01E17 - Die Schatzsuche + Bus verpasst.ext
where only the second (, 2) hyphen "-" is replaced by an plus sign "+".

Done. Problem solved!

All till now was testing only.
If you are satisfied with this result press the Rename button to do the actual renaming itself.

- - -

More examples?
OK, here we go....

And how would you remove just the first coma?

To get:
SpongeBob Schwammkopf, S01E17 - Die Schatzsuche - Bus verpasst.ext

use EXPRESSION: %f(",","",1,1)
or just %f(",", ,1,1)

which means: find an coma and replace with nothing, or in other words: remove it.
Then the first "1" means start at FIRST occurrence of coma found,
and the second "1" means: work on ONE occurrence only, then stop the work.

You can make an another test run with %f(",", ,2,1)

- - -

And how do both replacements (hyphen and coma) at the same time?

Easy, just use the command separator ";" between both expressions:
%f("-","+",2);%f(",",,1,1)

Note that you can also use more then one "String replacement" modifier on one expression like:
%f("-","+",2)(",",,1,1)

                                          http://scarabee-software.net/forum/viewtopic.php?id=273

But he has something even better:
use your favorite text editor (or even Word with VBA)
where you are familiar with scripting for your advanced modification needs!

Here is an quick how to for you:

1.) launch Siren with the files you want to rename (Or open Siren and browse for an folder)

2a.) use "Edit > Copy the selection > Current names" to copy the whole file name to the clipboard
       or,
2b.) if you want to just edit the "base name" without the extension, do this simple steps:
       -- in the Expression field write  %b  *1
       -- now you get as Future name the file name without the extension
       -- click the column header with right mouse button and choose "Copy selected files data" to the clipboard

            *1 ( or "%p_%f"            for   ParentFolder_FileName,
                   or "%pa_%b_%e"  for   FullPath_FileName_Extension,
                   or..., or..., or....,      just  right click the expression field ;-)   )

3a.) use an text editor with scripting support (e.g. PSPad, Boxer, EmEditor, (HippoEDIT), UltraEdit)
       or Word and his VBA scripting, and use that scripting feature to modify your names,
       or use simple rectangular selecting, or zero-width selecting to change parts of your file.
       Or save the exported file names to an temp file and let an script (e.g. VBScript, JScript, AutoHotkey, AutoIt)
       or command line tool like SED (i),AWK (i) or SFK (i) run against it.
       Warning: don't add or remove lines, or your files get messed up if you confirm the preview!

4.) Once you are finished, copy the modified names to the clipboard again.

5.) back in Siren use the expression %C to insert the clipboard line-by-line
       Use %C.%e to add an dot and with %e the original extension of the file.

Now watch the preview in the Future name column, and if all went fine do the renaming.

Here is an picture how this could look:

placeholder, later more...

HTH? 

However, I'm wondering if you could give an example of how to renumber starting with a given number (such as renumbering from 6901 on).

Thanks!

DO Expression:
%b(s/([^_]+)_([^_]+)(.*)/\2_\1\3/).%e

Explanation:

%b(    s/    ([^_]+)_([^_]+)(.*)    /    \2_\1\3    /   )   .%e

%b  ====> work on the base name without the extension

( s/ / / ) => do an regular expression search and replace => ( s/match/replace/mod)

.%e ====> add the original extension

([^_]+)_  ==> find one-or-more sign which are not an underscore, till an underscore is found ===> "Renamer" + "_", store all match inside (..) in group 1

([^_]+) ====> again the same but till the end (or till an underscore is matched by next expression) ===> "Siren", store in group 2

(.*) =======> maybe match none-or-more of any sign ==> <none> or "_Utility" or "_Utility_2002-2010" , store in group 3

Replace with what is matched in group 2, add an underscore your own, then the content of group 1, then 3 if any ==> \2_\1\3

USE:
0000%b(s/.+\((\d+).+/\1/);%b(s/img_.+/0/)(-3)

EXPLANATION:
0000 -----------------------> Add a few padding zeros, no matter how much but as many as the shortest string needs.
%b(s/.+\((\d+).+/\1/)--> extract digits between (...)
; ---------------------------> separate different actions
%b(s/img_.+/0/) --------> rename file without (...) to 0
(-3) ------------------------> keep the last three signs from string only.

0000(-3) is used to pad numbers with different length (1 or 10 or 100) to the same end length (001 and 010 and 100)
First i add a many 0's so all strings have at least the length they should have, then i take the amount of signs i really want from the right.

Is there a way to extract the Date Time Sent from an Outlook email message (msg file) and rename the file similar to expression %dm.*

Example future name desired:

Thanks in advance.

although XYplorer have an good till advanced renamer tool, it lacks an more advanced one,
here comes Siren renamer to work

http://www.scarabee-software.net/en/siren.html
Just download and unpack the Siren_201.zip (400kB) into your XYplorer folder:
One EXE   1MB (350kB UPX)
One INI (after first launch)

Some examples how to use Siren from XYplorer:

      ::run """<xypath>\Siren.exe"" <curpath>";   //current folder name itself

      ::run """<xypath>\Siren.exe"" <curpath>\";   //show all files inside current folder

      ::run """<xypath>\Siren.exe"" <selitems>";  //rename the items currently selected

      ::run """<xypath>\Siren.exe"" /F *.<curext>"; //all files from same type as the currently selected file type

Execute Siren with an rename expression,.. rename and end:

      Siren command line usage: escape the quotes by an leading \
                                                             /E %b(\"_\",\" \").%e

      XYplorer usage: escape the quotes by doubling them
      ::run """<xypath>\Siren.exe"" <selitems> /E ""%b(\""_\"",\"" \"").%e"" /P";

Advice:  - For a complicated expression, use a favorite ("/A") rather than an expression ("/E") like above.

Some examples what can be done with Siren renamer by Scarabée Software:
    (Note:
              there are no check boxes or many input fields, just an field to enter an expression.
              Read the help and try an right click into this expression bar.)

      %f   : the file name
      %b   : the "base" name
      %e   : the name extension

Every variable can be postfixed by a "[]" modifier.  It will be split into an array of substrings.
  The usage is: "[ array-element no. n, "separator" ]"
  Example: for "Artist - Title.mp3" the expression "%b[2] - %b[1].%e" will exchange Artist and Title.

Every variable can be postfixed by a "()" modifier for - Substring extraction
  The usage is: "(start pos, amount of chars)"
  Example: for "The Artist - Title.mp3" the expression "%b(5).%e" will crop the first four signs.
  Example: for "random string, fixed string.ext" the expression "%b(-12).%e" will only keep the last 12 signs.
  Example: for "Sales, random string, 2010.ext" the expression "%b(1,5) %b(-4).%e" will crop the random string in the mid.

Every variable can be postfixed by a "()" modifier for - String replacement
  The usage is: "("find me", "replacement", starting occurrence, number of occurrences to proceed, case sensitive)"
  Example: for "The Artist feat singer - Title stinking feat.mp3" the expression "%b("feat", "feet", 2).%e" will replace the second 'feat' to 'feet' only.

Every variable can be postfixed by a "()" modifier for - Modification by regular expression
  The usage is: "(s/ match regexp / replacement fmt / modifier)"
  Example: for "Document 09-2010.ext" the expression "%b(s/(\d\d)-(\d\d\d\d)/\2-\1/).%e" will exchange '09-2010' to '2010-09'

Bon week-end

Is it possible to change the command so instead of 001 002 etc at the end of a filename, you get A B etc?  Thanks very much for any help.
