move files with mule

I want to use Mule for moving and processing files. I'm trying to move the same file to different folders with a flow and an "all router" but it fails.

This works:

    <flow name="testflow2Flow1" doc:name="testflow2Flow1">
    <file:inbound-endpoint path="C:\IN" fileAge="10000" responseTimeout="10000" doc:name="File"/>
    <set-variable variableName="tempfilename" value="#[header:originalFilename]" doc:name="Variable"/>
    <file:outbound-endpoint path="C:\OUT" responseTimeout="10000" doc:name="File"/>
</flow>

enter image description here

But this don't!

    <flow name="testflow2Flow1" doc:name="testflow2Flow1">
    <file:inbound-endpoint path="C:\IN" fileAge="10000" responseTimeout="10000" doc:name="File"/>
    <set-variable variableName="tempfilename" value="#[header:originalFilename]" doc:name="Variable"/>
    <all doc:name="All">
        <processor-chain>
            <file:outbound-endpoint path="C:\OUT" responseTimeout="10000" doc:name="File"/>
        </processor-chain>
    </all>
</flow>

enter image description here

I get this exception:

You need to transform InputFileStream to a byt array. Set a global transformer(Go to File connector properties-->Transformers-->Add). Select File to Byte Array option. Connector config will look like this.

file:inbound-endpoint path="C:\File Input" responseTimeout="10000" transformer-refs="File_to_Byte_Array" doc:name="File"/>

InputFileStream you can not copy as it is to a variable.

Adding this <object-to-byte-array-transformer/> transformer after your inbound endpoint will make it work.

<flow name="testflow2Flow1" doc:name="testflow2Flow1">
    <file:inbound-endpoint path="C:\IN" fileAge="10000" responseTimeout="10000" doc:name="File"/>
    <object-to-byte-array-transformer/>
    <set-variable variableName="tempfilename" value="#[header:originalFilename]" doc:name="Variable"/>
    <all doc:name="All">            
        <file:outbound-endpoint path="C:\OUT" responseTimeout="10000" doc:name="File"/>
        <file:outbound-endpoint path="C:\OUT1" responseTimeout="10000" doc:name="File"/>        
    </all>
</flow>

I think why it failed is because mule was trying to read file as stream and write as stream; which was fine in your 1st case.

But in second flow because you want to write to more than one place, thats not possible with streaming. With addition of this transformer, now you have complete payload in memory and that can be written to more than one.
