before you perform an export to disk in premiere, you must have enough disk space for your exported project. if you have low disk space during an export, premiere can become unstable. to avoid this problem, you should specify a high low disk space warning level. this will enable you to delete files when you??re warned, and resume the export.

to set your low disk space warning level:
1 choose edit ] preferences ] general and still image.
2 in the low disk space warning level box, enter a high warning level, such as 100000 k.
3 click ok to return to your project.
