Component Version macOS Windows Linux Server iOS SDK

MBS( "Files.List"; Path { ; filter; ExtensionFilter } )   More


Parameter Description Example Flags
Path Native path to the directory. "C:\Test"
filter Optional, limits what is returned.
Default is 0 to report all files.
Pass a combination of 1 for showing only files, 2 for showing only directories and 4 for showing only visible items.
Add 8 if the path includes the file name specification with wildcards; a.k.a glob.
Combined pass 4+1 for visible files or 2+1 for visible directories.
5 Optional
ExtensionFilter Optional, a filter for getting only files with matching file extension. ".txt" Optional


Returns list of files separated by return.


Queries list of file names in folder.
The list of names is separated by new line character.
This function needs a native path. Please use Path.FileMakerPathToNativePath function in order to convert a FileMaker style path to a native path.
With filter parameter being 8 on Windows, you can pass a path with wildcards directly and ExtensionFilter parameter is ignored. This is not supported on macOS.

See also Files.ListRecursive. You can filter result with List.MatchesPostfix to get list with one file extension only.

Our plugin does not sort and return the files in the order the OS returned them. If you need sorting, please check List.Sort function. Also use List.RemovePrefix or List.RemovePostfix to filter list further.

On macOS, if you can't read a directory, please also check privacy system settings for whether FileMaker has permissions to look into desktop, documents or downloads folder or remote volumes.

    count = ValueCount(list);
    index = 1
] ;
    index ≤ count ;
    filename = GetValue(list; index);
    filepath = MBS("Path.AddPathComponent"; folder; filename);
    // query size for each file
    size = MBS( "Files.FileSize"; filepath);
    names = names & filename & " -> " & size & ¶;
    index = index + 1
] ;
// return all the names
names )
