I can kinda repro running RC2 (5744)... It's easier to explain if the list is in Details view:

1. Click on a folder in the Folders list.

2. Click and hold the mouse button down on the white space next to a folder/file name in the details pane (be sure to keep the mouse cursor inside the Name column), and then drag it out to select the other folders/files.

3. Note that the folders/files just selected don't gain focus (they get highlighted grey). The folder name in the Folder list is still selected, so when I press the Delete key on my keyboard it asks to delete that folder.

This behaviour is inconsistent, because if I click and hold down on the white space on the far right (i.e. in the empty column area that doesn't get highlighted when you hover over it) and then drag to select the folders/files, the details pane gets focus, and those files/folders are selected and highlighted blue. I also think in XP doing the three steps above would normally put the focus into the details pane and delete the selected files/folders, not the folder in the folder tree.

Also, it's not actually important which column I start dragging from or which view I am are in, as long as it's within the area that gets highlighted when I hover over the item, and that the part I click on is whitespace (otherwise it will drag the file/folder instead of doing a selection.)

I was able to reproduce it on RC2 as well. From what I gather he is saying that the right pane is not taking focus correctly when drag selecting files. So his scenario is correct that you are drilling down with the folder tree on the left, get to the one you are looking for and drag select the files. At that point you expect the right pane to have focus when you hit delete but it doesn't actually get focus until you left click (and thereby unselecting the folders you just selected).

Snip grabs focus so you can't get a true pic of it. It is simply though that the left keeps focus even after group selecting on the right. I doubt this behavior is planned as it only does it when drag selecting starting from the top or left, and never from the bottom or right.

Actually it looks like there is a bug here. I'm repro'ing it on a newer build - will have to try on the current RTM build tomorrow and find out if this is known.

My repro steps are:

1) Select a folder in the tree view.

2) Click-and-drag to multiselect in the listview (must be in list or details mode) STARTING on top of an item (not in the empty space below the items).

3) Press the delete key.

Thanks for posting this.

And what build might that be? ;)

Thanks for explaining it correctly. Now I can reproduce the bug (Build 5840). Windows simply fails to switch focus in this scenario.

The wording in the "delete" dialog is also quite bad.

If you are deleting a folder with files - e.g. "c:\windows\bunch-of-files\", the dialog will say "Deleting from c:\windows\..." (without mentioning the name of the folder). That sure have scared me many times, because it makes me think that it's actually emptying the root folder.

I filed this "bug" a while ago (RC1) - hope they fixed it.

(Note: I'm talking about the dialog shown while deleting files, usually this will only be visible if you are deleting a bunch of files/folders)

Yep. Haha, I hope an executive at Citrix accidentally wipes his Documents folder because of this on November 30th. Maybe that would get MS's attention.

... and that the fix is sitting on MS's servers by Jan 30 ready and waiting to be downloaded...

I don't know how you could know that since none of you have the RTM build yet... right? :crazy:

The issue with the listview not taking focus during this specific kind of selection was identified too late to be fixed for the RTM build and there are several mitigating factors that prevented it from being considered recall-class. However the post-RTM fix for this issue has been prioritized appropriately.

Any update on this __critical__ bug? I was made aware of this bug before I used Vista RTM and it has still caught me out twice. The first time I didn't lose anything important but the second time I almost deleted my profile!! (luckily all I seemed to lose was my Outlook e-mail - which wasn't bad because it was mainly empty).

But this bug could have some very serious consequences. This topic should be pinned, or perhaps re written in a "Known RTM bugs" pinned thread. Will an update be made over windows update or would it be a seperate downloadable hotfix?

Read the thread!!

The bug basically is to do with highlighting files for deletion in Windows Explorer. If you select files from inside a folder it is a possibility that it could delete the entire folder.

The bug is with Windows Explorer, in list or detail mode. I will try to explain how to reproduce the bug but a picture or video would be much better:

In the left tree view - select your folder. The folder will now have a blue outline.

In the right pane hold the left mouse button down and highlight the files you wish to delete. They should be highlighted in blue.

Now this is where the bug occurs - if the files are still highlighted in blue then thats fine. But if the parent folder is now highlighted in blue and the files highlighted in grey, you would delete the parent folder if you pressed delete.

The bug is in the standard listview control and actually existed in XP as well (not a regression). Although the bug wasn't exposed in Explorer in XP because XP doesn't use full-row select. It was apparently in Vista for a long long time and never reported by any beta testers (and it was definitely an oversight by internal testing but they can't find them all - that's why we have betas!) until I saw this thead here.

It's ugly, I won't deny that. But very, very few people will ever hit it in normal use. I also don't really see it causing anyone to actually lose anything since the dialog that comes up accurately tells you what you're trying to delete - plus the recycle bin and volume shadow copy are pretty good safety nets for just this sort of thing. We're all on vacation this week but I'll follow up soon and figure out if/when a fix might be pushed to WU.

This topic is now closed to further replies.

    • Claude on Windows is eating up massive amounts of RAM, with no way to stop it

      By TheGhostPhantom · Posted

      This article does not make sense and it’s very evident, the bug wasn’t confirmed to exist, because the application itself runs on editions of Windows which make it impossible to run Hyper-V VMs on, “Basically, Claude Desktop on Windows spins up a 1.8GB Hyper-V virtual machine if you use Claude Cowork or agent mode even once.”, suggests the bug is caused by something else otherwise it would only happen to users with the capability of running Hyper-V VMs and that’s only if Hyper-V was enabled which is by default not enabled. The true issue is that the author who reported the bug used the incorrect terminology.
    • Stack Overflow is launching a version of itself for AI agents

      By TheGhostPhantom · Posted

      “To prevent hallucination issues and keep the database clean, the platform uses a multi-agent verification loop to check code quality.” - This absolutely isn’t happening. ”Before the massive rise of LLMs, which tanked its traffic by about 50% over the last couple of years, Stack Overflow was the go-to website for millions of programmers seeking coding solutions.” - It still is trusted, because the community of users, blocked other users from submitting false and misleading answers generated by AI agents that can be convinced something it generated is actually incorrect even if it’s actually correct. The company itself doesn’t know what it wants to be so it keeps trying and failing to introduce AI features to the platform. This effort will also fail, already submitted one successful poison pill, look forward to generating more.

    • Proton releases Proton Drive CLI for Windows, Mac, and Linux

      By noobient · Posted

      Completely irrelevant as long as pricing is garbage. With OneDrive I get storage for about $18 / TB for a year. With Proton it's $96. For the record, Google One is around $48, Dropbox $69, iCloud $60. In other words, Proton is the worst value BY FAR. Not to mention with OneDrive I get full desktop and web office suites for 6 people.
