Does Peopletools 8.59 have a Filename Size Limit for GetFile ?

Hello - I'm writing out a file from an App Engine and the filename is coming from an external source - and I want to truncate the filename if it is too long.

I see online that the Unix/Linux filename limit is 255 char.

What is Peopletools 8.59 filename length limit? Is it the same as linux?

Code snippet:

 &out_document_file = GetFile(&out_path | &out_doc_name, "W", %FilePath_Absolute);
 &out_document_file.WriteBase64StringToBinary(MAM05704_AET.M_AM_STRING.Value); /* write the base64 string out as binary (image) to file */
 &out_document_file.Close();

Thanks!!
