Default Batch file to uniquely nmame & random rename JPEG images [randomnames.bat]

I was re-populating a re-imaged system due to BSOD corrupting the boot
where I had a devil of a time _finding_ this old randomnames.bat file
which will randomly name any number of JPEG files to unique names each.

I use it when I take a bunch of screenshots over long periods of time, and
edit them one by one, as needed, where the names aren't in the order of the
screenshots anyway, and there are too many to rename manually, so I rename
them randomly - which makes each one distinct.

If you need it, it's useful.
o If you don't need it - it's just a sample of randomizing algorithms.

What I love about Usene is it's filled with useful hints & ideas.

Just because you use %random% 3 times doesn't make it impossible to get
the same name twice. Hopefully you never write SW where live depends on.

This is much easier done with the GUI using explorer. Select all files
you want to rename and click "rename". If you display the files ordered
by date, then also the filenames have this order.

Hi Herbert Kleebauer,

Thank you for assessing the script, where I fully agree that it's only
random as much as running pseudo @rand 3 times will make it so. Agreed.

you want to rename and click "rename". If you display the files ordered
by date, then also the filenames have this order.


I had forgotten about that feature of Windows, so again, I thank you for
remaining me, and the others on this newsgroup of the context sensitive
rename menu item.

I just tested it, by the following process, which worked just fine:
a. I selected 75 photos in the Windows explorer
b. I right clicked on one, and selected rename & typed "a"
c. It renamed them successively from "a(1).jpg" to "a(75).jpg"

In addition, while we're listing batch renaming capabilities, Irfanview
freeware has batch renaming capabilities based on regular expressions:
o Irfanview Batch Rename

While none are truly random neither Irfanview nor rename seem to be random.

Don't click on "one", but on the first one of the selected files,
because this one is renamed first and then all other files in the
displayed order.

and selected rename & typed "a"


Don't type "a" but "a(10001)" to get a proper sequence of file names.

Arlen's really not very bright.

That doesn't seem to work in Explorer for me. If I select a number of files
and click "rename" (right-click, rename), it only renames one file. Maybe
because I use StartIsBack?
