I use this py script to delete unnecessary files on SD card

'''
written by kuowei.liao@schot.com

Note: the player must running with LFN

1. install python on your laptop
https://www.python.org/downloads/

2. open command prompt and enter the command below to install the "requests" module 
pip install requests

3. run the "deleteSdFiles.py" py script from your file location to delete SD unnecessary files
python d:\deleteSdFiles.py <BS player ip> <DWS password (option)>
e.g.:
with DWS password enabled:
python d:\deleteSdFiles.py 192.168.0.43 password

with DWS password disabled:
python d:\deleteSdFiles.py 192.168.0.43

Note that BrightAuthor and BrightAuthor:connected publishes manage storage on their own and files are deleted only as space is necessary to avoid unnecessary card wear.

Unfortunately, unless something has changed, the "Limit storage space by function" option is disabled by default when installing BrightAuthor and BA:Con (it should be enabled by default).

People need to go in and enable it themselves, or SD cards will fill to capacity and the player will stop loading updated content, especially if you are using HTML and/or MRSS content that is updating all the time (like weather images).

For BrightAuthor:

Go to Edit->Preferences and then click on the Storage tab.

Make sure "Limit storage space by function" is checked, and "Specify percentages" selected, with values based on your content usage.

For BA:Con:

Click on the Down Arrow next to ADMIN on the top menu, and select Application Preferences. At the bottom of the list click the Right Arrow next to Storage to expand the options, and make sure "Enable Limit Storage" is checked, and "Percent" is selected, with values based on your content usage.

After these changes are made, re-publish your presentation to your player(s), in which they will now delete older accumulated content on the storage card.

Depending on player model and firmware, your player may (or may not) reboot several times in the process of catching up over the next approximately 20-60 minutes depending on size of SD card. After the player has caught up, then typically it will continue the process automatically without rebooting, deleting older files as needed so the SD Card does not fill up completely again.
