'I'm a site collection admin, with no access to Central Admin. I'm having to remove the 255 character limit from a multi-line text column, to accommodate some very long scientific article formal titles. So, I found I can do it (in my test library) this way, but don't understand the warning message:
In Library Settings/Change Column/Additional Column Settings/ Allow unlimited length in document libraries - change from default No, to Yes.
Gives this warning about uploading through website:
"Columns with long text are not supported by most applications for editing documents and could result in a loss of data. Only remove this limit if users will be uploading documents through the website, and not saving directly from the application."
I know this is probably very basic, but I thought all uploads were "through the website" because SharePoint is basically a website. I can't find any articles to explain this basic point. So, first half of question - what does that phrase mean? How do I tell my users to not to "save directly from the application"?
In production, we are anticipating several hundred to a few thousand scientific articles in this library. This column will only be used for a metadata export using "Export to Excel". There will be absolutely no editing of docs in this library, just upload, enter metadata, and export (to a non-ShPt site). So second half of question is - will this very long text field be a problem performance wise?
Thanks - keep it simple! Delighted to get this far - and thanks for previous help.
