Rename with random string or digit number, randomize name

Q: Before secure deleting my files and overwriting with zeros,... how can i randomize the file names first?

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}.*
