Is there / Will there be any support for tags for files in DOpus?
I mean being able to give a file some tags and afterwards being able to display only the files with a given tag in the whole system or just within a chosen folder.
...Firefox' Awesomebar (the addressbar is called like that since 3.0) has "dirtified" me for a traditional directory structure...
You can use the description field for "tagging" files. That´s the closest at the moment. But tags have been requested a couple of times, so maybe there a chance something like that could be included in future versions.
thanks, i will try that to fill the gap in my soul 
is the description field in DOpus a conglomeration of the description fields found in the "details" tab of file's properties dialog?
i'm currently sitting on linux, i will experiment with that later.
No, you can view the descriptions either by right clicking the columns bar & choosing "more", then adding that column or via -> options -> foldert options. You can make an user command or button then:
SetAttr Description
You can display (and find/filter on) many of the fields in the Details tab, though.
wouldn't the "Keywords" column from "Documents" be more natural to use?
there are some of the fields also present in the category "Special" over here: "Author", "Comments", "Keywords", "Pagecount", "Subject" and "Title".
have you got those too? the contents from category "Documents" aren't displayed here, why do these exist?
BUG: when i activate one of the columns "Comments" or "Pagecount", DOpus crashes immediately without an error.
Does that happen even in an empty directory? If so it could indicate a bad shell extension (see here).
If it only happens in certain places, see if you can work out which file(s) in those place(s) trigger the crash and then please send a sample either as an attachment here or directly to GPSoftware (support link in my sig) so that we at the forum or GPSoft can try to reproduce the problem.
ok, i will try when i sit on windows again.
i tried in two different directories (non-empty), but the crashes didn't happen until i scrolled to the right until the according columns got visible.
you got the same columns in category "Special" too, right? 'cause i've also got some SVN and GIT entries there, so these might stem from an application i installed. shouldn't crash though.
If we're talking about the Special category then those are definitely shell extension columns (that's what the category is for).
It shouldn't crash but the bug could be in the shell extension rather than Opus. Working out which extension provides the column and which files trigger the crash is the first step.
If you look in the Documents category there are columns in there which show comments and page-counts for documents using code built into Opus rather than shell extensions.
in an empty folder dopus doesn't crash, but as soon as i create an empty folder it's gone.
so it's some shell extension i installed? how can i find out which program/library sits behind it?
Follow the steps in the FAQ I linked to.
sorry, i overlooked the link in your previous post.
Alright then, the bad guy was the "OpenOffice.org Column Handler 3.00".
ah i see now why the "Description" field and not the "Keywords" field: the desription field is naturally supported by DOpus.
is there a way to change the "Keywords" field with DOpus Raw Commands?
is there a reason why the Description field is preferred over the Keywords field?
one think that's not that nice with using the description dialog:
it's not possible to add one tag to several files in one go if i don't want to overwrite the files' previous tags (when they are not the same for all selected files).
Looks like it crashes more than just Opus:
I am just bumping for a tag plugin. I like DOPUS for browsing but I (shame on me) find the virtual folders system still a little too rigid for my needs--namely because I have files that need to be stored in multiple virtual folders (e.g. - an article on chinese history goes in the chinese folder and the history folder, which are both in the school folder). Multiple tags would be a lot easier.
I am using Taggedfrog right now and I find it incredibly awesome and easy to use--its only flaw is that it is not integrated into Dopus.
DO is a filemanager, not document manager. While both may seem identical at first sight, they are very different beings. Files are physical entities, documents are abstract. Files use simple hierarchical database (aka filesystem) for storage, documents usually use relational data store etc etc.
I think it would be more feasible to have direct support in DO for some document management system(s) (like we have for other external tools: GDS, Windows Messenger, or Flickr). Or just for Windows Search v4.
