From the manual:-
Storage System
Press to enter the store and recall setting interface.
The internal memory (Local Disk) of this oscilloscope is 90.5 MByte. It provides a USB Host interface at the front panel to connect USB storage device for external storage. The USB storage device connected is marked as "Disk D".
Storage Type
Press ? Storage to select the desired storage type. The default is "Picture". The storage and recall descriptions of each type are as follows.
1. Picture
Save the screen image to external memory in ".png", ".bmp8", ".bmp24", ".jpeg" or ".tiff" format. You can specify the file name and saving directory and save the corresponding parameter file (*.txt) under the same directory using the same file name. This parameter file is the same as the "Parameters" function. The recall of image and parameter files is not supported.
After selecting this type:
Press to select the desired storage format.
Press to enable or disable the parameter save function.
Press to enable or disable the invert function.
Press to select the desired storage color. It can be set to "Gray" or "Color".
Tip
After a USB storage device (FAT32 format, flash memory) is connected, press
at the front panel to quickly save the current screen image under the root directory of the USB storage device.
2. Traces
Save the waveform data of all enabled channels (analog channel and digital channel) to the external memory in "*.trc" format. When loading the traces file, display the waveform data on the screen directly. After the file is loaded, the loaded waveform will not change when you adjust the settings (such as the horizontal scale and vertical scale) of the oscilloscope.
Note:
? The reading and saving operations of the file in ".trc" format can only be completed on the oscilloscope.

3. Waves
Save the main setting information (e.g. "On/Off" states of the channels, vertical scale and horizontal scale) and waveform data of all enabled channels (analog channel and digital channel) to the external memory in "*.wfm" format. When the waves file is loaded, the system will set the oscilloscope based on its existing saved setting information of the oscilloscope and recall all the waveform data. When the loading is complete, the oscilloscope will be in the "STOP" state. Under such situation, you can adjust the waveform display by changing the setting (such as the horizontal scale and vertical scale) of the oscilloscope; or you can adopt the one-key measurement or cursor measurement to measure the waveform parameters.
Note:
? The reading and saving operations of the file in ".wfm" format can only be completed on the oscilloscope.
? If you set the oscilloscope to be in the "RUN" state, the oscilloscope will start over the waveform sampling. (That means, the loaded waveform data will be cleared.)
4. Setups
Save the settings of the oscilloscope to internal or external memory in "*.stp" format. The stored settings can be recalled.
5. CSV
Save the screen waveform data of all enabled channels (analog channel and digital channel) or the memory data of the specified enabled channels to the external memory in "*.csv" format. You can specify the file name and the saving directory and save the corresponding parameter file (*.txt) under the same directory using the same file name. This parameter file is the same as the "Parameters" function. The recall of CSV and parameter files is not supported.
After selecting this type:
Press to select "Screen" or "Memory". After selecting "Memory", press
to select the desired channel (Note: Only channels currently enabled can be selected).
Press to enable or disable the parameter save function.
Press to choose whether to add sequence numbers for the waveform points in the CSV file. You can select "ON" or "OFF" and the default is "ON" (namely add the sequence number).
6. Parameters
Save the parameters of the screen waveform to the external memory in "*.txt" format. The parameter storage contains the system information (such as the
