Undeletable artifacts

[David P]

Some of the times I run Hugin, it produces partial results in tif &
jpg format that I cannot delete.

If I rerun the stitcher, it produces an error.
here's the logfile.
Are the two issues related?

Are the files still undeletable after a reboot? If not, there might be an issue with the files never being closed by the application. I can't imagine why this would happen, but it is a possibility. A workaround might be to use unlocker [0], in this case.

If this is not the case, another possibility may be that somehow the files are saved such that you don't have rights to delete the file. Could you open a command prompt (cmd.exe), browse to the directory mentioned where the intermediate files are stored ("cd /d Z:\Artefacts\Imagery\Photo\Calendric\2011\02\24" if that's where the files are stored), and run xcacls on the temporary file (e.g. "xcacls 2011-02-240000.tif")? This shows the access control list (ACL) associated with the file. Could you post the results here?

By the way, I'm not sure but this last log line strikes me as abnormal? Maybe someone else can comment on this?

Bart,
thanks for the reply.

I have tried rebooting on one occasion - with no effect.
I still get the error message "Cannot delete file: Cannot read from
the source file or disk"

I have also tried using cmd.exe to delete, with no effect.
I will try unlocker.

my machine doesn't recognise the xcacls command.

Hmm you're on WinXP right? I may have posted a Vista/7-specific version of cacls. There have been a number of commands which provide ACL-related functionality. You need to replace 'xcacls' with just 'cacls' [0], my mistake. Alternatively, you can use the Windows Explorer GUI to check file rights, by right-clicking the affected files, choosing 'Properties', and browse the 'Security' tab. BTW: I don't have XP at hand anymore, so some names may be wrong.
