b2sdk._internal.scan.folder

class b2sdk._internal.scan.folder.AbstractFolder[source]

Bases: object

Interface to a folder full of files, which might be a B2 bucket, a virtual folder in a B2 bucket, or a directory on a local file system.

Files in B2 may have multiple versions, while files in local folders have just one.

abstract all_files(reporter, policies_manager=<b2sdk._internal.scan.policies.ScanPoliciesManager object>)[source]

Return an iterator over all of the files in the folder, in the order that B2 uses.

It also performs filtering using policies manager.

No matter what the folder separator on the local file system is, “/” is used in the returned file names.

If a file is found, but does not exist (for example due to a broken symlink or a race), reporter will be informed about each such problem.

Parameters:

  • reporter (Optional[ProgressReport]) – a place to report errors

  • policies_manager – a policies manager object

Return type:

Iterator[AbstractPath]

abstract folder_type()[source]

Return one of: ‘b2’, ‘local’.

Return type:

str

abstract make_full_path(file_name)[source]

Return the full path to the file.

Parameters:

file_name (str) – a file name

Return type:

str

b2sdk._internal.scan.folder.join_b2_path(relative_dir_path, file_name)[source]

Like os.path.join, but for B2 file names where the root directory is called ‘’.

Parameters:

  • relative_dir_path (str | Path) –

  • file_name (str) –

Yield all files.

Parameters:
