Firstly, being a long term reader but new registered member so a big hello from me.
Secondly just to say I've attempted a search to find a solution to this issue but cant appear to find one... if I've missed one then my apologies and will gladly be directed there if highlighted.
Thirdly my apologies for the lengthy post but I thought it best to give as much info and background as possible.
Very recently I've purchased a pre-loved NS01 (2 x 400GB model) server for a very good price. It's use is to basically replace an aging classic ipod/docking station combo fed into my amp to play my ripped cd collection and for this purpose it suits my needs very well.
It all functions correctly and came with the previous owners music still installed but as this was not to my taste I deleted (correctly via the Naim app for iOS). This effectively cleared the internal hard drive(s) of all music... or so I thought.
Upon inspection of the internal drive structure (via a Windows Laptop) I discovered the following folders in the NS01's music directory :
EX, HQ, LQ, MQ and playlists
My cd collection rip correctly to the MQ directory.
MP3 copies of said rips are correctly placed to the LQ directory. Not a feature I will use but this tested correctly.
HQ directory is empty. I understand this isn't used by the end user but possibly by Naim engineers if ever needed... feel free to correct me if I am wrong or misunderstand.
However in the EX directory there are many sub directories of CD rips. These are in the file path EX/Artist/Album and then files are in the format of songname.wav.DEL and have a file type of DEL file. Along with these files in each album directory there is the usual XML, Text and folder documents for that album so these appear to be CD rips as opposed to downloads but I could be mistaken.
I understand, from a search on these forums, these are files marked for deletion but have not yet been deleted in the recycle bin in the DTC.
The problem is I cant delete these files. In fact they cant even be SEEN to be deleted in the Naim iOS app or the DTC on my Windows 10 laptop. I wouldn't even know these files existed via the iOS app and DTC. The recycle bin in the DTC is empty so if my theory in the paragraph above is correct something is amiss here. I know I shouldn't delete/alter the NS01 directory by deleting files directly from my laptop but it wont let me anyway as I am told I need permission from the NS01/Naim to delete these files.
I've tested deleting my own files and this works fine so the delete function is not an issue here.
These files are taking up approx. 60GB of space and clearly this is a significant proportion of my storage that could be used for my own collection.
I may be missing something obvious here but I cant seem the find a solution. How do I delete these files? Is this possible from a user perspective?
Thanks in advance for reading this and any advice and/or solutions greatly appreciated.
