# Ubuntu – Can’t modify files in the shared folder (virtualbox, guest is Ubuntu, host is windows 7)

file-sharingvirtualboxwindows

I'm using virtual-box. The guest is Ubuntu. The host is Windows 7. I have a shared folder (shared by the host and the guest).

The problem is that in the guest (Ubuntu) I cannot rename/delete/edit the files in the shared folder. For instance, after I edit the file and try to save it I get the following error message:

Could not save the file fileName. Unexpected error: Error renaming temporary file: text file busy

In the host (Windows) I can rename/edit/delete without any problem. What can I do?

You may suffer from bug #34813, where access to shares on Windows systems is broken. Access to files on Ubuntu hosts is not affected.

## Troubleshoot Shared Folders in Virtual Box

To investigate if your shared folders are setup correctly you may go through the following steps:

• Install the latest release of Virtual Box.

• Guest users need to be in the group vboxsf for auto-mounted shares.
(e.g. sudo mount -t vboxsf -o uid=1000 sharename mountpoint)
