one set of excel files on shared folder opens slower (very) than others

[psunith]

we have a set of excel files and the biggest one is only 1.35Mb. When we open these files they take longer than usual and longer than our liking to open. the files are stored in a QNAP NAS shared folder. The shared folder is mapped to several users.

We have tried opening these files with 4 users and its the same, it takes a while for the excel app to open, then shows the percentage of the file opening and then opens.

we are on M365 with Excel 2016 fully updated. These files are in the same folder and have been using the same template from 2014 and files are saved year wise, the opening very slow issue is with all these files. We have much larger excel files on different folders and we have no such issues, its just these set of files.

Any advise on what we can do to make it work normally?
