Get Files Count

This operation returns the number of files and optionally directories located in the specified path. Additional options include:

  • pattern filtering - counts files and directories which match the pattern.
  • recursive counting - when enabled, counts all matching files and directories while recursively traversing the directory structure.
// NON-BLOCKING METHODS
public void getFileCount(String path, AsyncCallback<Integer> responder);
public void getFileCount(String path, String pattern, AsyncCallback<Integer> responder);
public void getFileCount(String path, String pattern, boolean recursive, AsyncCallback<Integer> responder);
public void getFileCount(String path, String pattern, boolean recursive, boolean countDirectories, AsyncCallback<Integer> responder);

// BLOCKING METHODS
public int getFileCount(String path);
public int getFileCount(String path, String pattern);
public int getFileCount(String path, String pattern, boolean recursive);
public int getFileCount(String path, String pattern, boolean recursive, boolean countDirectories);

where:

Argument                Description
path Path of a directory in the Backendless files storage starting with /
pattern A pattern which the counted files and optionally directories (if the recursive parameter is set to true) must match. Backendless supports two formats for pattern: glob and regular expressions. You can specify the pattern matching format to use with a prefix as shown below:
glob:profilepic*.png or regex:pic[0-9]\.png. If the prefix format is not specified, Backendless treats the pattern as glob.
recursive If set to true, recursively count matching files in all subdirectories.
countDirectories If set to true, count directories in addition to files.

Example

String path = "web";
String pattern = "*.html";
boolean recursive = true;
boolean countDirectories = true;
Backendless.Files.getFileCount( path, pattern, recursive, countDirectories, new AsyncCallback<Integer>()
{
    @Override
    public void handleResponse( Integer response )
    {
        int fileCount = response;
    }

    @Override
    public void handleFault( BackendlessFault fault )
    {

    }
} );

Codeless Reference

files_api_get_files_count_1

where:

Argument                Description
path A path identifying a directory where files and folders must be counted. The path must start with the root directory of the remote file storage.
pattern A pattern which the counted files and optionally directories (if the recursive parameter is set to true) must match. Backendless supports two formats for pattern: glob and regular expressions. You can specify the pattern matching format to use with a prefix as shown below:
glob:profilepic*.png or regex:pic[0-9]\.png. If the prefix format is not specified, Backendless treats the pattern as glob.
recursive If set to true, recursively counts files in all subdirectories.
count directories If set to true, counts directories in addition to files.

Returns the number of files and/or directories in the specified path.

Consider the following files stored in the days directory:

files_api_get_files_count_2

The example below counts the number of files in the "days" directory.

files_api_get_files_count_3

The result of this operation will look as shown below after the Codeless logic runs:
