"Failed to copy the file filezilla.xml" message

[p3p]

I have just installed Filezilla Client 3.0.10.
My system is a Windows XP SP2.

Frequently appears this message:
"Failed to create backup of xml file"

Sometimes appears when connecting to ftp server or when you close the application.
When you try to save the preferences of the application the message always appears.

After that message apperas another information:

20:02:35: Failed to copy the file 'C:\Documents and Settings\Dani\Datos de programa\FileZilla\filezilla.xml' to 'C:\Documents and Settings\Dani\Datos de programa\FileZilla\filezilla.xml~' (error 1224: la operación solicitada no se puede realizar en un archivo con una sección asignada a usuario abierta.)

Is your disk full or nearly full? Or is your disk write-protected?

Is your disk full or nearly full? Or is your disk write-protected?

No. There is 20 GB of free space.
The disk is not write protected. I have tested that the directory "Application Data\FileZilla" has the correct owner and write permissions.
I made a fresh install of Windows and FileZilla, so I suppose that there is a little bug in file permissions.
But if there is a bug more people should be affected.

Are you using any virus scanners or "security solutions"? What happens if you uninstall (only safe way to fully disable) them for a test?

[p3p]

I am not using any antivirus. I am using a firewall (Outpost Firewall), but I have disabled it and stopped the service and the problem persists.

I have reinstalled the Filezilla client and the problem persists.

The message is:
3:09:28: Failed to copy the file 'C:\Documents and Settings\Dani\Datos de programa\FileZilla\filezilla.xml' to 'C:\Documents and Settings\Dani\Datos de programa\FileZilla\filezilla.xml~' (error 1224: la operación solicitada no se puede realizar en un archivo con una sección asignada a usuario abierta.)

Actually, the file "filezilla.xml~" is wrote correctly as a copy of "filezilla.xml" when the message appears. However, sometimes the file is removed after the message windows is closed by the user. When the file "filezilla.xml~" is not removed when the message appears, is removed on the next start of the application.

English translation of:
error 1224: la operación solicitada no se puede realizar en un archivo con una sección asignada a usuario abierta.

error 1224: the operation can not be done in a file with a opened user assigned section.

Is this error description useful?

Some other program still has FileZilla.xml opened. This can't be FileZilla itself, as all access to the settings files is protected by a mutex and the file is only opened inside the critical section and closed before leaving it.

You can use Process Monitor to find out which program has the file opened:  http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx

I have tried installing Filezilla client in another Windows XP SP2 installation (other partition) and the problem does not appear.
So I suppose that another program is causing the problem, maybe Outpost Firewall Pro 2008.

Close since error message indicates this isn't a problem with FileZilla but rather with the system.
