The cause of this is almost always tag alongs. They register with the kernel and get notified when a file is about to be closed, so they promptly open it and then do whatever with it. Number one whatever is virus scanners, but the culprits can also include backup tools, source control tools and various Explorer extensions that like to display status/icons for files.

Re: [sqlite] DB file locked when no other process using it - Found word(s) list error in the Text body
I've seen this kind of issue before - after closing the sqlite3 database, I can't delete the file (I would want to do this if I opened an sqlite3 database and found it to be corrupt). As sqlite's connection handle has closed, I assume sqlite should no longer have any handles open to the database; however Windows (which I'm running under) may well still have open handles to the file waiting to flush cached changes to disk. The way I resolve this is to try deleting the file over and over until either it succeeds, or it has still failed to delete after a set time (say a few seconds). Under Windows, you can see if any processes have a handle open to the file through SysInternals' Process Explorer (go to Find->Find Handle or Dll... and enter the sqlite file name - it'll highlight the first process it finds with an open handle to that file). You can then force close the handle. I'm not sure how to do this programmatically though, or how to find/release locks on other operating systems.

I think it was probably caused by a process crashing part way through. Is there a way to force release the lock?
