Grouping of File and Folder Names

If the names of files and folders can be alphabetically grouped according to whether they start with the letters A-H, I-P and Q-Z, they should also be able to be sorted numerically according to the same principle. That is: 0-9, 10-19 … 90-99 and 100-199, 900-999 and so on and so forth. Maybe instead of names, they should be called “sequences” within a folder??? In any case, this does not seem to be possible, neither in Windows Explorer, File Explorer nor in Directory Opus. Am I wrong? If so, how would I do this manually or programmatically?

That could be done using a script add-in column. They can group files any way you want.

I really do not know how to do a script add-in column. Is there any way that I can learn it?

Here's a script column that assigns files to groups of numbers.

function OnInit(initData) { = 'LogGroup';
    initData.version = '2023-07-06';
    initData.url = '';
    initData.desc = '';
    initData.default_enable = true;
    initData.min_version = '12.0';

function OnAddColumns(addColData) {
    var col = addColData.AddColumn(); = 'LogGroup';
    col.justify = 'right';
    col.method = 'OnColumn';

function OnColumn(scriptColData) {
    var item = scriptColData.item;
    if (item.is_dir) return;

    var itemNo = item.name_stem.replace(/0*(\d+).*/, '$1');

    if (itemNo == '') {
        scriptColData.value = 'none';

    var groupSize = Math.pow(10, itemNo.length - 1);
    if (groupSize < 10) groupSize = 10;

    var start = Math.floor(Number(itemNo) / groupSize) * groupSize;
    var end = start + groupSize - 1;
    scriptColData.value = start + '..' + end;

To install, save ColumnLogGroup.js.txt to

%appdata%\GPSoftware\Directory Opus\Script AddIns

The column can be toggled with

Set COLUMNSTOGGLE="scp:LogGroup/LogGroup(!,a,0)"

The files can be grouped with

Set GROUPBY=scp:LogGroup/LogGroup

This is good for numbered files only. Lettered files and folders at all are not grouped properly.

Yes. That was the idea. Feel free to enhance the script.
