I am trying to copy files from one SharePoint folder to another, using REST API, but I see that although all the files are copied, only some get default value for a particular column, while others do not. I have no idea why.
EDIT: On a closer look, I found that the new office documents types (.docx, .xlsx, .pptx etc.) get the default values, while the old office document types (.doc, .xls, .ppt) do not get the values.
Also the old office documents get the values only when they are coming from a source folder which already contains the columns in the destination folder.
I am wondering why the old office documents do not get the values and if anything can be done.
Is it a bug in SharePoint Server or am I missing any configuration to make all files work?
