A. 1. Manage save files: Regularly delete old or unnecessary save files from within PPSSPP to free up space. Go to the save file directory and remove files you no longer need. 2. Use external storage: If your device supports it, move save files to an external SD card to free up internal storage.

B. 3. Compress save files: If possible, use a file compression tool to reduce the size of save files before storing them.
