I was working in a branch 'A' and created a folder 'MyFolder' in this branch. I committed my changes but didn't push the changes to master. Then, I did git checkout master and shifted to master branch. Now, the folder 'MyFolder' shouldn't be there but it's present with a hidden file .fuse_hidden0000adbd00000004. There is nothing else in the 'MyFolder' folder in master.
Can I delete the folder 'MyFolder' from master?
.fuse_hidden files are related to FUSE filesystems, and should generally get cleaned up automatically. There are lots of references for this scattered about the web.

You should be able to safely delete the file, and Git doesn't track directories. It is always "safe" to remove an empty directory in a Git repository.
