Note: if you want to delete file only from git use below:
git rm --cached file1.txt
If you want to delete also from hard disk:
git rm file1.txt
If you want to remove a folder(the folder may contain few files) so, you should remove using recursive command, as below:
git rm -r foldername
If you want to remove a folder inside another folder
git rm -r parentFolder/childFolder
Then, you can commit
and push
as usual. However, if you want to recover deleted folder, you can follow this: recover deleted files from git is possible.
From doc:
git rm [-f | --force] [-n] [-r] [--cached] [--ignore-unmatch] [--quiet] [--] <file>…
OPTIONS
<file>…
Files to remove. Fileglobs (e.g. *.c) can be given to remove all matching files. If you want Git to expand file glob characters, you
may need to shell-escape them. A leading directory name (e.g. dir to
remove dir/file1 and dir/file2) can be given to remove all files in
the directory, and recursively all sub-directories, but this requires
the -r option to be explicitly given.
-f
--force
Override the up-to-date check.
-n
--dry-run
Don’t actually remove any file(s). Instead, just show if they exist in the index and would otherwise be removed by the command.
-r
Allow recursive removal when a leading directory name is given.
--
This option can be used to separate command-line options from the list of files, (useful when filenames might be mistaken for
command-line options).
--cached
Use this option to unstage and remove paths only from the index. Working tree files, whether modified or not, will be left alone.
--ignore-unmatch
Exit with a zero status even if no files matched.
-q
--quiet
git rm normally outputs one line (in the form of an rm command) for each file removed. This option suppresses that output.

git rm
is the right answer, but remember that the file will still be there in history. If you want to remove a file because it had sensitive information, you'll need to do something more drastic. (Changing history, especially for content you've already pushed, is a drastic action, and should be avoided if possible.) – Keith Thompson
