Apologies for what seems an extremely basic question, but DOpus and Windows Explorer both seem to exhibit the following rather odd behaviours on my PC's ordinary NTFS D: drive (Windows 7 Pro).
If I add a new .txt file to a folder, the folder date is updated to the present.
If I use UltraEdit Studio to edit a .log file in a folder, the folder date is updated to the present.
If I use Notepad to edit a .log file in a folder, the folder date does not change.
I can't make any sense of these experiments. To make things more confusing, the "Date modified" of the folders upwards in the tree from the folders in question is behaving differently again in a way that I can't pin down.
Whatever is going on seems to be Windows behaviour, so my second question is:
Does DOpus have an alternative "Date modified" column for folders that will update the folder date to the present whenever either a file in the tree below it is edited, or a new file is added somewhere in the tree below?
All I was trying to do was perform a quick visual check to see which folders in one of my directories on D: drive had new or updated files in their trees. Hardly rocket science, but it looks as if one needs to use a properly constructed DOpus search for such things.
Think of a folder as a container. If its contents are changed, its modified date reflects this change. One could presume then that UltraEdit is creating (and perhaps deleting) a temporary file or changing some file (maybe a hidden one) in the folder.
UltraEdit is probably doing a safe save (i.e. creating a new file) which is triggering the folder date to be updated.
Windows does not "bubble" folder dates up the tree; only the immediate parent folder's date is modified.
Thanks for those explanations. That makes sense of why edits using UltraEdit, but not edits using Notepad, are changing the folder dates.
As to my second question --- I was hopefully looking for a DOpus-provided heading that would update the folder date when any file in the folder, or lower in the tree, is edited. (For example, DOpus has an alternative file size heading that gives the "Size on disk".) But given the fact that DOpus is only displaying data from Windows, I don't expect that such a heading could ever exist.
A quick note to say that Opus 10.2 + Video sorted out what I was trying to do --- a quick visual check of any updated or new files so that I could process them. "Label filters" in "Preferences - - > Favorites and Recent - - > File and Folder Labels" can now colour all files in past a specified date in a folder and its subfolders. Once all those files are processed, the specified date can be changed to the present. Thanks for the added flexibility, and thanks for the video explaining it.
