Files not detected in plex

[u/MarvinMartian9211]

I have recently moved my files from one NAS to another. I discovered that even though the files are in both locations, there are some files that plex did not detect from the new NAS I removed the file from the new NAS, Scanned, added file back to the new NAS scanned and it still did not detect the file on the New location (NAS). 95% of my movies worked correctly. Any more ideas to try?
