Can't change shared file read-only attribute

Reported by: TwoBit Owned by:
Component: shared folders Version: VirtualBox 2.0.4
Keywords: Cc:
Guest type: Windows Host type: other


A Windows client using a shared folder from a Windows host is unable to change the read-only attribute of files on the host. Reproducibility is simple: Open Windows Explorer on the client, select a file on the host and right-click to bring up its properties. Change the read-only checkbox and click the OK button. This has no effect.

I'm having the same problem. I've reported it  here:

I'll paste the post for convenience:

VirtualBox 1.5.6_OSE Host: Ubuntu Heron Guest: Vista SP1 Guest Addns installed

In Ubuntu host I've created /my/share/ and done chmod a+rwx /my/share

In VirtualBox settings, I've set this to my shared folder & ensured 'Read Only' attribute is unset.

In Vista SP1 client, I have mapped this to my Y: drive

I point Windows Explorer to Y:, right click, Create New Folder (Minor)Problem: It's invisible. Needs a rightclick+refresh to see it.

Major Problem: Right click on it, Properties: its 'Read Only' attribute is set. I clear it, Apply, ok. Now I bring up the properties again. It has reverted!!!

Total mystery. I can write files into this folder. I can create an empty doc, type into it, save it.

This problem is affecting me because I need to set Visual Studio to build into the shared folder: Y:\ReleaseBuild\ and Visual Studio is not allowing it, presumably as it sees it as readonly.

Please someone fix!!!

I am experiencing the same problem with VirtualBox 2.2.0 on a Linux 32bit host and a Windows XP SP3 guest

I can confirm that problem.

File permissions won't be remembered and applications (except Explorer) can't write to the Shared Folder.

Linux host, XP SP3 guest.

This bug still present in new Virtual Box 3.0. In Virtual Box 2.2 I work with files normally, but after update I can`t save files from Lazarus to shared folder because any file on create (or write changes) from Lazarus has 400 permissions. Host: Ubuntu 8.04.2 Client: Windows XP SP3

Same behaviour on Ver 3.0 Host: Fedora 9 Guest: W2K (see ticket #3712).

copy with Explorer creates 664 copy with totalcommander creates 400 - delete of the files from totalcommander is possible copy with cmd creates 400 - delete of the files from cmd is possible

Seeing the read-only bug on VirtualBox 3.0.0, Ubuntu 9.04 host, Windows XP Pro SP3 guest.

This was working fine prior to VirtualBox 3.0 upgrade, now the main software I use cannot save updated versions of its existing project files to my shared folder, and I cannot change the read-only setting of the hosts's shared folders/files.

This bug is threatening to make VirtualBox useless to me, as this is pretty much the only software I run in VirtualBox. I may investigate reverting to an older version if this doesn't get addressed soon.

Also, I removed Guest Additions v3.x and installed Guest Additions v2.1.4 as suggested by others and in other discussions of related bugs, but this had no affect for me.
