Limitation in filter on FS LIST and FS-OPS-DIR

I have the same problem in both named nodes and wondering if anyone as a solution or documentation that explains the problem.

I have files which have parenthesis in their filename but those are never found when I search for them.
If I try to list the whole content of a folder they are found in the file list array but when I use parenthesis in the filter, they aren't found.

Without looking at how the filtering is done (e.g. regex / glob etc) your options are limited to:

  1. Do it yourself using fs
  2. Do a secondary filter yourself (e.g. msg.payload = msg.files.filter(e => /[()]/.test(e)) )
  3. raise an issue on the nodes asking for clarification and / or support finding special characters.

Can you show us what you are entering please and the names of files that it is not finding, so that we can test it.

I have two files in the folder:
test_new_PressTalk_jch - Copy (7).OL-package
test_new_PressTalk_jch - Copy (7)

The filter is
test_new_PressTalk_jch - Copy (7)

It is necessary to escape the the parenthesis. Try this
test_new_PressTalk_jch - Copy \(7\)

Edit, also you will need a * on the end, otherwise it will find only exact matching files, not the ones with extra text on the end.
test_new_PressTalk_jch - Copy \(7\)*

That seems to work when I use the mask directly in the field but I am having problem setting the mask insisde a msg.payload.filenamemask variable. Any tips?

I am trying to do it via JSONATA like this:


Sorry, I don't do jsonata

The regex would be


Or to only test for (number)


Thank you so much works! :wink:
