"File not found" in Dynamic Input. File path too long?

[Philippa]

Hello,

I am running a flow with Dynamic Input, and our files - stored on a central cloud server - have very long file path names.

We have control over some of the naming, and have been able to get the path lengths under 260, but this will be a recurring issue for us. I understand that Windows 10 removed the 260 character length limit, but it seems like it is still a part of Alteryx?

Has anyone found a longer term fix than manually shortening the file path names?

Thanks!

Philippa

@Philippa,

I created a filename = C:\Users\markf\Downloads\I am an unreasonably long filename given the challenge to be found via an Alteryx dynamic input but I do realize that I am not quite the 260 bytes asked in the question I should be long enough to test a theory.csv

Reading from a DIR tool, I see this file as one of the files that I need to read via the DYNAMIC INPUT tool.  No worries!  I inserted a formula and created an update to the FullPath field as:

[Directory]+[ShortFileName]

The result was = C:\Users\markf\Downloads\IAMANU~1.CSV

The data was read without error, warning or other maladies.

Cheers,

Mark

Thanks, Mark! I'll give this a try. Sounds very reasonable!

Great question I was wondering this too!

This solution works if it is the filename that is causing the path to be excessively long, but I would think the more common scenario is that the directory structure is very deep and the [Directory] portion by itself is over 260 characters.  Any suggestions on how to deal with this situation?

Yes this is the issue for me as well!

You need to first make sure that windows itself allows for Long Paths. You can do this by editing the Registry Setting: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem - LongPathsEnabled (Setting the value to 1). Or if you do not have access to edit your registry you will need to have your network admin adjust the group policy to allow the Long Paths.

(The registry change will not take effect until you restart your computer)
