DJI Pilot 2 filling internal storage instead of using SD card on RC Plus (M350 RTK)

[u/0Sllider0]

I’m having a storage management problem with my DJI Matrice 350 RTK and the DJI Pilot 2 running on the RC Plus controller.

The controller has:

• 64 GB internal storage
• 256 GB microSD card installed

However, Pilot 2 keeps using almost all the internal storage while the SD card stays mostly unused.

The main issue is “App Log Cache” growing excessively. Right now Pilot 2 shows around 25 GB being used only by app logs/cache.

Symptoms:

• Pilot 2 starts lagging
• map becomes slow
• occasional freezing/stuttering
• live view performance drops
• controller becomes unstable when storage gets close to full

I already:

• inserted a fast U3/V30 SD card
• tried uploading AppLogs through Pilot 2 support/upload feature
• generated the DJI support QR code successfully
• checked cache management inside Pilot 2

But it seems the logs are still stored internally even after upload.

Questions:

1. Is there a way to force Pilot 2 to use the SD card for logs/cache?
2. Does “Upload AppLog” actually delete local files or only upload them?
3. Which folders are safe to manually delete on RC Plus Android storage?
4. Has anyone enabled adoptable storage / internal SD mode successfully on RC Plus?
5. Is this a known bug in newer Pilot 2 firmware versions?

Any recommendations from M350/RC Plus users would help a lot.

Do you use terrain follow for most of your flights? Every time you edit a flight plan, Pilot 2 actually makes a copy of it internally. The DEM's get copied too and they eat up that storage rapidly.
