Coldfusion locking files when I upload then I can't delete

[lonnborg]

I have been having a problem deleting images for a while now. Everytime I upload a file with cffile I am unable to delete it for an unknown amount of time. I cant delete it with cffile delete or even delete it on the server manually. Its not a permissions issue because I can delete other files in the folder. Just the ones that were uploaded recently cannot be deleted or renamed. I ran the process explorer and it was telling me that jrun.exe had a handle on the picture names that were not able to be deleted. Is there a way to tell jrun.exe to relese the photo before deletion?

Process Explorer Window

Process PID Type Handle or DLL
jrun.exe 111580 Handle C:\Inetpub\www\website\photo i can not delete.jpg

Since you mentioned JPEG, are you displaying the image just after the upload? In that case, it's the HTTP server (Apache, IIS, etc.) that's probably locking your file for a while. I don't know if there's really a way to overcome this.

What I would do (in a Content management system, for example), would be a specific file-task queue, which stores a record in the database if the file deletion didn't work (use try-catch), and then run a specific page once in a while (cfschedule) which tries to delete the files that are waiting for their doom.
