Change two files

Hello!

When i have my list of files, for example dsc_001, dsc_002, dcs_003, dsc_004, dsc_005, dsc_006 i would like to make it organize the files 2 and 2. So dsc_001 and dsc_002 become a copy of eachother. So new name on my files dsc_001, dsc_002, would be dsc_001 (1) and dsc_001 (2), and so on, so instead of renaming one i want to rename 2 to the same name, and the list of files is approximately 1500 files. Is this possible?

You don't mean a real file copy, to make the same file content, don't you?
You just want to rename the file names, right?

Yes exactly. Sorry if I made it complicated.

EDIT:
there is a bug if my 'idx' becomes '10' and then again at '20'...

I will try to find time to provide an update.

Are you sure you have no gaps in your current numbering?
Not smtg like: 1, 2, 5, 6, 7, 12, 13?
But straight 1,2,3,4,5,6,7,8,9..... with no missing numbers.


Then you can use this JavaScript.
Attention, there is no errorhandling, if your current names
are not in order this renaming will mess it up (have a backup!)

USE this Script for the first PREVIEW:
------------------------------------------
if(index==0){idx=index +1};
digits = parseInt(item.name.slice(-3));
if(digits %2 == 0){
ser = ' (' + 2 + ')'; num=idx; idx++;
}else{
ser = ' (' + 1 + ')'; num=idx;
}
num = ('0000'+num).slice(-3);
return item.newBasename+' to '+ 'dsc_'+ num + ser;
------------------------------------------


.
.

# # #

If the names looks good in the preview, remove the "item.newBasename+' to '+" part:

TO get:
dsc_001 (1).ext
dsc_001 (2).ext
dsc_002 (1).ext
dsc_002 (2).ext
dsc_003 (1).ext
dsc_003 (2).ext
dsc_004 (1).ext
dsc_004 (2).ext
dsc_005 (1).ext
dsc_005 (2).ext

------------------------------------------
if(index==0){idx=index +1};
digits = parseInt(item.name.slice(-3));
if(digits %2 == 0){
ser = ' (' + 2 + ')'; num=idx; idx++;
}else{
ser = ' (' + 1 + ')'; num=idx;
}
num = ('0000'+num).slice(-3);
return 'dsc_'+ num + ser;
------------------------------------------

HTH?


index = is the current file index, provide from ARen
digits = are the last three signs of the original name, the three digits
idx = is my own file index
num = is the new numbering for the file name, based on my idx
ser = is the serialization (1) / (2)


I' am sure a good scripter is able to clean and improve my code. But it should work as it is now too.

Perfect thank you very much! This will make my life so muck easier. But another question, If i want to change the files like this but i want the numbers to start on another number than DSC_001. For example:

Dsc_0413 >> 47987(1)
Dsc_0414 >> 47987(2)
Dsc_0415 >> 47988(1)
Dsc_0416 >> 47988(2)
Dsc_0417 >> 47989(1)
Dsc_0418 >> 47989(2)

How do i change this?
So grateful for your help.

Then we would initialize my 'idx' var with '47987'
if(index==0){idx=47987};


And remove the number formatting line:
num = ('0000'+num).slice(-3);

and that 'dsc' string from the new name:
'dsc_'+





Something like this:


------------------------------------------
// START NUMBER:
// if(index==0){idx=index +1};
if(index==0){idx=47987};

// GET LAST THREE SIGNS FROM NAME:
digits = parseInt(item.name.slice(-3));

//IF DIGITS ARE EVEN
if(digits %2 == 0){
ser = ' (' + 2 + ')'; num=idx; idx++;
}else{
//IF DIGITS ARE ODD
ser = ' (' + 1 + ')'; num=idx;
}

// NUMBER PADDING:
//num = ('0000'+num).slice(-3);

// COMPOSE THE NEW NAME:
return num + ser;
------------------------------------------






But first I have to find the bug in my algorithm.
