Daily refresh
 

I produce a daily inventory summary pivot table from the current day's
download. I have created a master file to contain all the data from the
newest download on Sheet1 and a pivot table on Sheet2. When this works
properly, the macro runs and a simple refresh of the pivot table will get
the job done.

I am thinking a macro in the master file could delete the old data on
Sheet1 then search for the most recent download file and copy it to Sheet1
prior to doing the pivot table refresh. This procedure would need to be
repeated each day. So, how to make a macro look for a file based on ()Today
in the creation date and a string of text that is part of the file name every
day (e.g. 'inv')?
