Checkout all files that are missing or placeholders:
git lfs checkout
Checkout a specific couple of files:
git lfs checkout path/to/file1.png path/to/file2.png
Checkout a path with a merge conflict into separate files:
# Attempt merge with a branch that has a merge conflict
$ git merge conflicting-branch
CONFLICT (content): Merge conflict in path/to/conflicting/file.dat
# Checkout versions of the conflicting file into temp files
$ git lfs checkout --to ours.dat --ours path/to/conflicting/file.dat
$ git lfs checkout --to theirs.dat --theirs path/to/conflicting/file.dat
# Compare conflicting versions in ours.dat and theirs.dat,
# then resolve conflict (e.g., by choosing one version over
# the other, or creating a new version)
# Cleanup and continue with merge
$ rm ours.dat theirs.dat
$ git add path/to/conflicting/file.dat
$ git merge --continue
