How are you supposed to use the "Input Folder" node?

qruze

I'm trying to copy folders that are more recent than 7 days to another location; I've setup a flow with an input folder, which then goes to the File - Older than script, and that gets passed to a Copy File node.

The first two steps work ok, but the copy step fails with a

Execution error: Could not find file '[the dir name]'. at System.IO.FileInfo.get_Length() at FileFlows.Plugin.NodeParameters.CopyFile(String source, String destination, Boolean updateWorkingFile) in /src/Plugin/NodeParameters.cs:line 604 at FileFlows.BasicNodes.File.CopyFile.Execute(NodeParameters args) in /src/BasicNodes/File/CopyFile.cs:line 75 at FileFlows.FlowRunner.Runner.ExecuteFlow(Flow flow, IPluginService pluginLoader, List``1 runFlows, Boolean failure) in /src/FlowRunner/Runner.cs:line 416

I suppose this is because I'm passing a folder, and not a file, to the Copy File node, but I'm not sure how else I'm supposed to accomplish this...
Any help is appreciated 🙂

Created this to take care of it

In the meantime, I've added a script to the repository "Folder - Copy Folder" which will do what you need.

For "Source Directory" use "{folder.FullName}"
And for "Destination" wherever you want the directory to be copied to, eg "D:\temp{folder.Name}". {folder.Name} will copy the source folder name

Thanks for the quick reply!

I tried using the script, but run into a different error now:

The path it complains about looks ok, and is the correct path I'd expect the file to end up at.

Of note: I'm running this on Linux, and the folder path contains spaces. Don't know if that's relevant 🙂

/[the destination base path]/[the folder path]/[a file in the folder]

well yeah thats not a folder. that's a file

I've updated the script to the following:

function Script(SourceDirectory, DestinationDirectory)
 {
    let src = Flow.ReplaceVariables(SourceDirectory);
    let dest = Flow.ReplaceVariables(DestinationDirectory);
    let allDirectories = System.IO.Directory.GetDirectories(src, "*", System.IO.SearchOption.AllDirectories)

    System.IO.Directory.CreateDirectory(dest);

    for(let dir of allDirectories) 
    { 
        let dirToCreate = dir.replace(src, dest); 
        System.IO.Directory.CreateDirectory(dirToCreate); 
    }

    let allFiles = System.IO.Directory.GetFiles(src, "*.*", System.IO.SearchOption.AllDirectories);

    for (let newPath of allFiles) 
    {
    System.IO.File.Copy(newPath, newPath.replace(src, dest), true); 
    } 

    return 1;
 }

The first System.IO.Directory.CreateDirectory(dest); outside of the allDirectories loop was the key to solving my issue. As far as I can tell this method will do nothing if the directory it's trying to create already exists, so should be safe.

updated the script to run a check to see if the dir exists, and if not create it.
