It is important to know how you access the files and where they are located. Otherwise it is impossible to answer this question.

[darkmoon_uk]

If accessing as a resource it can be critical to prefix resource path with /

[kgurgul]

tbh it doesn't work no matter where I store them. I tested it on the app level or in the user home ('System.getProperty("user.home"))

[kgurgul]

I will check if prefix change anything

[darkmoon_uk]

By referencing DMG/MSI does this going that you're using Compose Multiplatform packaging?

[kgurgul]

yes

[darkmoon_uk]

If so, recommend using Compose Multiplatform Resources

[darkmoon_uk]

For which raw file resource handling is well documented and, I can attest, works

[darkmoon_uk]

Read up on CMP Resources

[kgurgul]

I'm not sure if it will be possible - I need to store file for DataStore

[darkmoon_uk]

Ok, let's take a step back. I don't feel you've really explained the use case clearly

[darkmoon_uk]

What is the file, where does it get created, how does it get used

[darkmoon_uk]

Then we can help

[kgurgul]

ok, I need a Path to a file which will be used to store data by androidx DataStore

[kgurgul]

so it looks like this

PreferenceDataStoreFactory.createWithPath(
            corruptionHandler = ReplaceFileCorruptionHandler(
                produceNewData = { emptyPreferences() },
            ),
            produceFile = {
                val configPath = getAppConfigPath("CPU-Info")
                "$configPath/$USER_PREFERENCES_NAME.preferences_pb".toPath()
            },
        )

fun getAppConfigPath(appName: String): String {
    val os = System.getProperty("os.name").lowercase()
    val appNamePath = appName.toPath()
    val configPath = when {
        os.startsWith("windows") -> {
            val dir = getLocalAppDataPath() ?: "/".toPath()
            dir / appNamePath
        }

        os.contains("os x") -> {
            getHomePath() / "Library/Preferences".toPath() / appNamePath
        }

        else -> {
            val dir = getXdgConfigPath() ?: (getHomePath() / ".config".toPath())
            dir / appNamePath
        }
    }
    return configPath.toString()
}

private fun getHomePath() = System.getProperty("user.home").toPath()

private fun getXdgConfigPath() = System.getenv("XDG_CONFIG_HOME")?.toPath()

private fun getLocalAppDataPath() = System.getenv("LOCALAPPDATA")?.toPath()

[kgurgul]

maybe it is an issue in DataStore itself because it can create a folder for file but not file itself. Strange part is that it works perfectly fine without packaging

[kgurgul]

and ofc it is datastore issue - https://stackoverflow.com/questions/79177464/kmp-compose-multiplatform-datastore-not-working-on-jvm-release-build

[kgurgul]

sorry for the confusion
