Could an applescript be causing this

Question

I've got a script which I have been using for three years to renumber raw and jpeg image files (using the Finder) and then using an image converter app I write archiving info to the exif data by creating a new exporter for each jpeg file and overwriting the old JPEG files.
I've been using it with Panther without any problems but recently machines running Tiger have been experiencing some problems.
One such problem is that the HD (start-up drive) begins to fill up only no visible files are being stored the on the HD (image files are burned onto DVD and then deleted from the drive) until finally the computer won't start for lack of drive space. Whatever files are taking up the drive space are invisible. In the last two years a hard drive had to be replaced and now after a year the new drive had to be reformatted (due to lack of space)and the OS reinstalled.
Could an applescript caused anything like this to occur? Has anyone had a similar experience? Apple says that is is due to the system shutting down incorrectly too many times but that doesn't sound right.
It only seems to occur with Tiger.

Answer 1

Anything's possible but without seeing the script its impossible to tell.
There are far more other options, though, when it comes to what's filling up your disk. The fact that you can't see the files hints that it isn't AppleScript.
The commonest cause for this is logging - some rampant process writing lots of log data that isn't getting cleaned up. Tracking down thoe files manualy can be a pain.
You might want to get a copy of Disk Inventory X or What size?, both of which will show you a graphical breakdown of your disk usage, making it easier to find the culprit.
