I have a folder set up on my SSD drive and when I open an album folder the files start to disappear like there being deleted then start to rebuild/appear again. This takes 30seconds or so, but very frustrating and slow. I have run virus software, optimised the drive, formatted the drive etc but still no different. I cant find anything on line to point what might be the issue. I have even transferred the files to a different drive and still it does the same. If anyone has a solution, or ideas why this is happening i would be most grateful

What kind of files are these?
Which OS is running?
What is your antivirus program?

Bit defender antivirus.
Run virus checks several times.
Formatted the drive
Optimised the drive
Updated drivers

Just wanted to make sure that you are not running a Mac.
There have been reports about the Windows defender to slow down the loading of files

> In the past I already noticed that the antivirus-software of windows-defender slows down the loading speed of files in MP3Tag dramatically: At this time my third-party antivirus-software (Avast) had been gotten accidently deactivated and windows-defender activated. This time I wanted to give windows-defender a second chance, deinstalled Avast and activated the defender. The same happened as before: Mp3Tag became very slow in loading files in spite of the activated library-function. I tes…
But if that does not play a role on your PC (please make sure that it really does not), then we have to look elsewhere:
