Camel file component picks up the file before permissions are set up

I have a camel file component which looks at a unix directory where files are
copied every 10 mins through an MFT process.
The MFT transfers around 80 files every 10 mins and then again modifies the
permissions on them.
But before the permissions are modified, the camel file component picks it
up for processing which results in Operation Not permitted error.
Is there an option in camel file component to check for permissions ?
