# Bug Report
Cannot read files under cordova.file.externalRootDirectory for Android 11
## Problem
Getting ready for move to Android 11 and new folder locations. I need to
move my app user files from old location into new location.
My old location for user files is
cordova.file.externalRootDirectory/crossstitch.
New location will be
cordova.file.externalRootDirectory/Android/data/com.crochetdesigns.crossstitch/.
However, when I set <preference name="AndroidPersistentFileLocation"
value="Compatibility" />and <preference name="AndroidPersistentFileLocation"
value="Compatibility" /> in config.xml, I can not read the files under old
folder to move them. I assume the change deadline is still Nov 1 2021. Then all
apps need to target 30.
If I do an update now and leave it targeted to 29 all is good. But that does
not leave users enough time to update the app, use the app to get files moved
before Nov 1 deadline. I have been trying to solve this problem for over a
month now. I have 11 apps in the playstore that I will need to do this for.
### What is expected to happen?
Allow apps targeted for 30 to read all files under
cordova.file.externalRootDirectory.
### What does actually happen?
can only read my .png files under
cordova.file.externalRootDirectory/crosssstitch folder

}
catch (error) {
alert(error);
}
},
feMovePattFiles: function (fileSystem) {
// folder already exists
try {
fileSystem.root.getDirectory("crossstitch", { create: true,
exclusive: false }, movePatFiles.feMovePatternFiles, movePatFiles.moveFail);
}
catch (error) {
alert(error);
}
},
feMovePatternFiles: function (directoryEntry) {
// read from cordova.file.externalRootDirectory + "crossstitch" + "/"
// read all the files in the folder
var reader = directoryEntry.createReader();
reader.readEntries(movePatFiles.getPatFileList,
movePatFiles.moveFail);
},
getPatFileList: function (entries) {
var patFiles = [];
for (var i = 0; i < entries.length; i++) {
// only finds my .png files
alert (entries[i].name);
}
return patFiles;
},
moveFail: function (error) {
alert("fail");
}
}
