Preferences path doesn't exist.

[milanbx]

Hi, any extension command ends up with this message, even if it is not true, as I am sure, the path exists:

    "esp8266fs.preferencesPath": "d:/Portable/PortableApps/Arduino/portable/preferences.txt",

./data folders exists too, and arduino.json contains following:

{
    "output": "d:\\VSCodeBuildTemp",
    "board": "esp8266:esp8266:generic",
    "sketch": "ESPrestAPI.ino",
    "configuration": "xtal=80,vt=flash,exception=disabled,stacksmash=disabled,ssl=all,mmu=3232,non32xfer=fast,ResetMethod=ck,CrystalFreq=26,FlashFreq=40,FlashMode=qio,eesz=1M64,led=2,sdk=nonosdk_191122,ip=lm2f,dbg=Disabled,lvl=None____,wipe=none,baud=921600",
    "port": "COM3",
    "programmer": "AVR ISP"
}

And here is part of settings.json:

    "esp8266fs.dataFiles": "./data",
    "esp8266fs.preferencesPath": "d:/Portable/PortableApps/Arduino/portable/preferences.txt",
    "esp8266fs.spiffsImage": "./temp/spiffs.image.bin",
    "esp8266fs.logLevel": "normal",
    "esp8266fs.mkspiffs.executable": "d:/Portable/PortableApps/Arduino/portable/packages/esp8266/tools/mkspiffs/3.0.4-gcc10.3-1757bed/mkspiffs.exe",
    "esp8266fs.mkspiffs.debugLevel": 0,
    "esp8266fs.mkspiffs.allFiles": true,
    "esp8266fs.esptool.verbosity": "vvv",
    "esp8266fs.esptool.py.before": "default_reset",
    "esp8266fs.esptool.py.after": "soft_reset",
    "esp8266fs.esptool.py.trace": false,
    "esp8266fs.espota.esp.port": 9889,

An ideas, what could be wrong? Thnx.
