Cx File Explorer Troubleshooting

Cx File Explorer access denied! What do I do?

Don’t panic! First of all, check whether you have downloaded the latest apk version of the app. Next, check whether the app is installed and working properly. If both are true then follow this guide:

  • Configure UFW (Uncomplicated Firewall) so you can access your PC’s IP with the Android app – in our case this is Cx File Explorer.
  • Login into your PC account. Open the properties of the shared folder and check “Allow others to create and delete files“.
  • On the permissions tab set “Others” to Access Files.
  • You will know whether it works or not if you can see the shared folder with your app.
  • Start transferring files.

If this doesn’t work you always can use SSH (scp or rsync) to push or pull files.

Beware, that starting from Android 11 the Android\data folder on your device may not be accessible. It has been set to private and you can only get access to this folder via ADB (Android Debug Bridge) on your computer.

How to fix Cx File Explorer loading error?

Try reinstalling the app and see if the error persists.

Cx File Explorer SMB not working! How do I fix it?

Check whether you have granted access to the shared folder. If you can’t access the files with your SMB client, use this code:

guest ok = yes

So now guests can get access to the shared folder.

How to set up Samba username:

Then go to the /etc/samba/smb.conf add these lines of code:

path = /cloud
writeable = yes
browseable = yes
create mask = 0777
directory mask = 0777
public = no

And restart:

sudo systemctl restart smbd

Cx File Explorer external codec not working!

Does it work at all? Cx File Explorer doesn’t have its own codecs, it relied on 3rd party extensions. If they do not work you won’t be able to use them.
