In Windows 11 File Explorer, we often use periods to prioritize the sort order of displayed folder names in the File Explorer window. For example, we often create a folder named "... Dump" (without the parentheses) for temporarily storing files to be deleted once it is shown they are no longer needed. The periods help always display the folder at the top of the File Explorer window listing.
Interestingly, we found an anomaly when using File Explorer to add this name to a folder on our Western Digital PR-4100 NAS drive. We added the folder (... Dump) to another subfolder on the NAS drive. Surprisingly, without any warning, it did NOT appear in the File Explorer window after being created. After some experimentation, we found it had been created but was created read-only and hidden. Any attempts to change the properties of the folder to unhide it were unsuccessful. Note that folders, without the preceding periods are created and display as would be expected.
Does anyone know if using the periods as a prefix to a folder name has any special significance for folders creating using File Explorer on a Western Digital NAS drive? Similarly, how can we change the properties of this folder so it will not be read-only or hidden? Thank you for any help.
