Data files seem to upload but don't appear in the Directory list #21

On my ESP32-WROOM the LittleFS Filesystem Uploader completes and I can see in it's output that it see's the 2 files in /data but when I use listDir(LittleFS, "/", 1); the files are missing. Also readFile(LittleFS, "/test.txt"); returns '- failed to open file for reading'

Any ideas on what I am missing? My program failed to mount the LittleFS until I ran arduino-littlefs-upload and now returns 'LittleFS Mount succeeded' so all good there, plus I can now create a file and append to it and then successfully read from it so the file system seems ok. I have tried rerunning the LittleFS Upload again, also reporting success but still the same problem.

OUTPUT:

I seem to have fixed it but unclear how. I changed the Board type and then changed it back again and then also changed the Partition Scheme from Minimal (1.3MB APP / 700KB SPIFFS) to the Default 4Mb with spiffs (1.2MB APP / 1.5 MB SPIFFS)

Strangely without re-running LittleFS Upload I can now see the files.

SOLUTION: After switching the partition back I know realize that the problem is the smaller SPIFFS size although I didn't record any warnings from either LittleFS Upload or the compiler about lack of FS space.
