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:

files_api_get_files_count_4
