The Ultra provides the following console commands for managing files on the SD card from a PC:
sd_delete? ? ??usage: sd_delete {filename}
sd_list? ? ??? ? ? ? usage: sd_list
sd_read? ? ??usage: sd_read {filename}
An example of using "sd_list" from a serial terminal on my computer (The number after the file names is the file size in bytes):
Sd_list

Using the attached Python script for?the Ultra, provided by Erik as an elementary example class library, a plot can be transferred from the Ultra to a PC without removing the SD card. The following examples list all the bmp files on the Ultra SD card and save "1.bmp" to "C:\Temp" on my PC.? The script is a quick re-write of tinysa.py, and as such, is not well commented and does not provide error checking.? There are Python experts in the group who can probably answer any questions you might have about running the scripts.? Martin may have already added the SD management features to his GitHub utility application.?
[C:\tinySA4\Scripts]python tinysa4.py -l *.bmp
0.bmp 307322
1.bmp 307322

[C:\tinySA4\Scripts]python tinysa4.py -r 1.bmp C:\Temp\1.bmp
