How do you prevent ASP.NET from creating too many temporary files? My website creates gigabytes of temporary files, and that overflows the main partition on the server. How do I prevent this from happening?
Setup a task in the task scheduler to clean up temporary files. I have no idea why this is not done by the OS (or by the creator of those files).
Where are these temp files beeing generated?
If it's in the "Temporary ASP.NET Files" folder, it's a result of your application beeing recompiled. Checkout MSDN for more information on dynamic compilation. One possible solution could be to relocate the temp directory.
You could try pre-compiling your site to avoid the generation of temp-files.
