[Zope] delete 'Data.fs.lock'

[Justin Xi ZHU]

Hi all,

I tried to install two Zope products on the same computer. One of them 
didn't stop cleanly. From then on, when I try to run the other product. The 
error message appeared.

'
Could not lock the database file. There must be another process that has 
opened the file.
'

I made sure all other processes are closed. The message still appeared. 
With the assistance of a member of the list, we isolated the problem to the 
Zope product that didn't stop cleanly, locked the 'Data.fs.lock'  file and 
failed to delete it. We need to delete it manually. However, when I try to 
delete it. This error message appeared.

'
Cannot delete Data.fs: It is being used by another or program. Close any 
programs that might be using the file and try again.
'
Again, I closed all applications. The error persists.

Regards, Justin
