When the memory capacity of Iflytek recording pen is low, it means that the storage space of recording pen is almost full, and it is impossible to continue recording or save new recording files. This situation is usually caused by the following reasons:

1. Insufficient storage space: The recording file occupies most of the storage space, resulting in very limited remaining free space.

2. Failure to clean up the recorded files in time: the storage space is full due to the long-term failure to clean up the recorded files, and it is impossible to record new files.

In order to solve this problem, the following measures can be taken:

1. Delete unnecessary recording files: browse the file list in the recorder and delete those unnecessary recording files to free up storage space. You can choose to delete according to the time and name of the recorded file.

2. Export and backup recording files: export some important recording files to computers or other storage devices, and back them up in time. This will free up storage space while retaining important recordings.

3. Use external storage devices: Iflytek recording pens usually support external storage devices, such as TF cards or USB flash drives. Storing the recording file in an external device can expand the storage capacity of the stylus.

4. Regularly clean up the storage space: It is recommended to regularly clean up the storage space in the recording pen and delete the recording files that are no longer needed to keep enough available space.

At the same time, we can also consider upgrading the storage capacity of the recording pen and choosing a larger model to meet more recording needs.

In a word, when the memory capacity of Iflytek recording pen is too low, we can release the storage space by deleting unnecessary files, exporting backups, using external storage devices and so on, and clean it regularly to keep enough available space.
