FTP List files in folder - putting filenames into array variable

(0) ShareShare
ReportReport
Posted on by RicFischer 13

I need to get a list of FTP files into an array of filenames only. I don't care about any other data in the array of BlobMetadata (https://docs.microsoft.com/en-us/connectors/ftp/#array-of-blobmetadata).

    He is one approach to store a list of all the files of an FTP folder into an array:

    Sample output: [ "100KB.zip", "1KB.zip", "1MB.zip", "512KB.zip" ]

    Thank you.

     

    However, I don't know how to filter the resulting array. What should I put in the "Choose a value" box? The Dynamic Content picker doesn't seem to let me pick an element of my FTP Files Array variable.

    There are several ways to achieve this. We'll can try the easier methods:

    item() needs to be entered as an expression in the expression editor.

    Or click Edit in advanced mode and enter the expression as you see below (this avoids using the expression editor):

    Or use a condition statement:

    Which will give you an array :

    I'm trying your first method because every day (this Flow will be execute once a day), this FTP file list is about 3800 files and I think that might be the quickest method.

     

    Thank you for your help!
