Remove all files from a Collection

Is it possible to quickly remove all files and folders from a collection (and from all Sub-Collections in that collection).
I have a collection that is changing contents all the time (it's files I want to copy to my phone). Once I copy the files, I'd like a quick way to remove all the files and folders from the Collection, but leave all the Sub-Collections.

This is one of my buttons. It deletes the existing collection and copies selected files/folders to a newly created Collection with the same collection name (as the deleted collection. So it deletes and recreates the same collection in one step and adds the selected files.

Unless the list of sub-collections is fixed, you'd probably need a script to clear everything from the collection and all sub-collections without also deleting the sub-collections themselves.

If the list of sub-collections is fixed then it's fairly easy.

Or you could have a button which deletes everything and then recreates new, empty (sub-)collections from a list of things you want created that would live in the button. That should also be quite simple.

How about deleting with a filter?


With a filter NoCollection like this:


(Quick shot with little testing)



Okay say the list of sub-collections is fixed. How could I do it?

lxp's suggestion looks better, if that works. I hadn't thought of that.

It works, but it isn't recursive -- you have to go into each sub-collection, select all, and run the button.

This script recursively removes all files and folders from a collection and its sub-collections:

function OnClick(clickData) {
    var cmd = clickData.func.command;
    var tab = clickData.func.sourcetab;
    cmd.RunCommand('Set UTILITY=otherlog');
    DOpus.Output('Items to be removed:\n');
    DOpus.Output('\n... done.');

function CleanCollection(coll) {
    var cmd = DOpus.Create.Command();
    var fsu = DOpus.FSUtil;
    var folderEnum = fsu.ReadDir(coll);
    while (!folderEnum.complete) {
        var fileItem = folderEnum.Next();
        if (String(fileItem.realpath).substr(0, 7) == 'coll:\/\/') {
        } else {
            var cmdLine = 'dopusrt \/col remove "' + coll + '" "' + + '"';
            // If you like the results, un-comment the following line
            // cmd.RunCommand(cmdLine);

Note that you have to edit the script to actually remove files and folders.


Hey thanks a lot, that's awesome!
Only problem is it doesn't work on files/folders with parentheses (maybe other wildcard characters too?).
I'm no Javascript expert, but my solution to escape all DOpus's wildcard characters was after this line:

var cmdLine = 'dopusrt \/col remove "' + coll + '" "' + + '"';

I added this line:

cmdLine = cmdLine.replace(/(\[|\]|\(|\)|\'|\~|\#)/g,'\'$1');

We'll add a scripting method to escape wildcard characters in the next update, to make things easier.
