[SOLVED] Problem with Git due to avmfritz binding

My master branch is up to date.
When I try to pull an old branch, I got these errors:
$ git checkout -b powermax lolodomo/powermax
error: The following untracked working tree files would be overwritten by checkout:
addons/binding/org.openhab.binding.avmfritz/src/main/java/org/openhab/binding/avmfritz/internal/config/AvmFritzConfiguration.java
addons/binding/org.openhab.binding.avmfritz/src/main/java/org/openhab/binding/avmfritz/internal/hardware/FritzahaContentExchange.java
addons/binding/org.openhab.binding.avmfritz/src/main/java/org/openhab/binding/avmfritz/internal/hardware/FritzahaWebInterface.java
Please move or remove them before you switch branches.
Aborting
How can I solve that ?

Hi Lolodomo,

I think you can safely remove them. Those files have been renamed.

Yes, case was changed for these 3 files.
I finally solved my problerm with this command: git config core.ignorecase true
