Ps software will use hard disk to temporarily store files when processing files, which is equivalent to computer memory. The name is temporary storage disk. You can set it on drive C. You can set it to D or another disk from the settings. If the system disk of drive C has enough space, it won't get stuck.

Does your software sometimes show that the temporary disk is full or not enough, and there is no tool to respond?
