Import Folder long path

Hi,

 

I am trying to use Import - Folder to pull a list of files in a folder/sub folders so I can do some analysis of the file types and where they are stored.  I'm running into an issue where there are stupid long file paths:

 

DataFormat.Error: The file name '\\server\share\folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\*' is longer than the system-defined maximum length.

 

I tried using "replace errors" in the query editor but that didn't work.

 

Anyone have any ideas?

 

Dan

Re: Import Folder long path

Hi @robofski ,

 

1. Create a parameter in Power query make the parameter is \\server\share\folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder.

 

2. Edit the M code in your Advanced editor to replace the file pate to parameter.

 

let
    Source = Folder.Files(""&Parameter1),
    #"Filtered Hidden Files1" = Table.SelectRows(Source, each [Attributes]?[Hidden]? <> true),
    #"Invoke Custom Function1" = Table.AddColumn(#"Filtered Hidden Files1", "Transform File from New folder", each #"Transform File from New folder"([Content])),
    #"Renamed Columns1" = Table.RenameColumns(#"Invoke Custom Function1", {"Name", "Source.Name"}),
    #"Removed Other Columns1" = Table.SelectColumns(#"Renamed Columns1", {"Source.Name", "Transform File from New folder"}),
    #"Expanded Table Column1" = Table.ExpandTableColumn(#"Removed Other Columns1", "Transform File from New folder", Table.ColumnNames(#"Transform File from New folder"(#"Sample File"))),
    #"Changed Type" = Table.TransformColumnTypes(#"Expanded Table Column1",{{"Source.Name", type text}, {"Date", type date}, {"cat", type text}, {"Sales", Int64.Type}})
in
    #"Changed Type"

Re: Import Folder long path

I have the same problem but sadly this solution does not work for me. 

it´s like the small link is always the same

 \\server\share\folder\another folder\another folder 

and than comes long link with different folders

\folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder.....

 

so even with Parameter its too long.

need Halp

 

I would like to combine Excel files from different folders as a one list.
