I have not investigated any great detail yet, but when I was backing up Documents and Settings from Drive C:, I found that Photoshop Elements had created a directory C:\Documents and Settings\henry\local settings\application data\adobe\camera raw\cache containing about 250 files named in the format "Cache0000000250.dat". At 4MB ish a go, this is a nice little Gigabyte, and if you are not aware of it ... If it had been in the middle of summer when I may take 200 or more in a day.
A file is created when you edit a raw format photo, and I have not found an option in Photoshop Elements which will allow me to get rid of it automatically. Mine were created between 21/11/07, which was when I installed Version 6.0 of Elements, and the day before yesterday when I found them. The My quick and dirty solution is a ".bat" file, but imagine if you have many users on a server!
I would like to suggest that this could be included in the application clean up part of CCleaner as part of a future release.
I have not yet done any further research to answer questions like:
- Is there a control I have not found to delete them?
- If so, when, and what controls the deletion?
- Etc ...
If anybody has further ideas about what research is needed, let me know.
