Twbx file size is unnaturally large when using wildcard union.

Issue

Packaged workbook (twbx) size is unnaturally large when wildcard union is used.

Environment

Tableau Desktop
Microsoft Excel

Resolution

Option 1:

Exclude all files not needed in the workbook out of the directory that is subject to wildcard union.

Option 2:

Input appropriately the file name you want to target for wildcard union. If necessary use the wildcard character, which is an asterisk (*), to match a sequence or pattern of characters in the Excel workbook

Cause

When using wildcard union, all of the files that match the specified pattern in the directory is included in the twbx file even though some of them may not be used in the workbook, which may impact the size of the twbx workbook.
