Using M-Files Importer to import files, but I would like to import the traditional folder

From what I recall the M-Files Importer uses a CSV file to import the files, and their metadata into M-Files. Assuming you already have a list of file paths for all the files in your source repository, If the source repo folders are well structured, for example: folder level 1 = property 1, folder level 2 property 2... then you could use some excel functionality, or possibly SQL, to extract the folder levels into their appropriate properties from the file paths. 

Feeding the resulting CSV file to the tool would import all the files and their metadata into M-Files. From there you should be able to make a view and group on the properties that you imported allowing you to mimic the same folder structure as the original repository. 

Thanks, that's what I figured too.
