Problem - you're unable to delete .WAV files created by FL Studio. This generally includes Windows stalling or hanging when trying to select or access these files.
This is caused by a long-standing bug in Windows where the PropertyHandler is unable to extract the metadata from a file containing a large number of slice markers. Each slice marker is saved as 'meta data' along with the WAV data in the file.
When exporting .WAV files from FL Studio deselect the 'Save ACIDized' and 'Save slice markers' options (FL Studio 12 and earlier) on the export dialog, as this is normally the cause for .WAV files created with more slice markers than the PropertyHandler can extract.
To fix your existing files, there are a couple of workarounds that will allow you to delete or access the files:
Delete the Slice Markers in Edison
1. Reboot your PC (do not try to open the files)
2. Launch FL Studio.
3. Add an instance of Edison to the project.
4. Open the .WAV file/s in Edison, one at a time, via 'File > Load sample'. You should see a large number of slice markers.
5. Use the 'Shift + Ctrl + Del' key combination to delete all markers.
6. In Edison select 'File > Save sample as...' and overwrite the original file.
You can now delete or access the updated file without Windows stalling and hanging.
Disable PropertyHandler for .WAV files (Be cautious when doing any of the following steps, follow the instructions precisely.)
1. Select 'Win + R' to open the Run dialog.
2. Type 'regedit' and select 'OK' to launch the Registry Editor.
3. From the Registry Editor navigate to:
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PropertySystem\SystemPropertyHandlers\.wav"
and..
"HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\PropertySystem\PropertyHandlers\.wav"
4. Double-click the .WAV String to edit the value data, which should be {e46787a1-4629-4423-a693-be1f003b2742}.
5. Add a '#' to the beginning of the value as follows {#e46787a1-4629-4423-a693-be1f003b2742}. This disables the PropertyHandler for .WAV files.
6. Press 'OK' to accept the changes.
Once you've made the changes to both Strings as noted above, you will be able to delete or access the .WAV files without Windows stalling or hanging. To undo the changes you simply follow the same steps and remove the '#' added to the value of the .WAV Strings in step 5.
Force Delete file using the Command Prompt
1. Select 'Win+R' keys to open the Run dialog.
2. Type cmd and press Enter to open the Command Prompt.
3. In the command prompt type del /f "File_path_here". (For example, del /f "C:\Users\Your_Username\Desktop\audio files\test file.wav")
4. Press Enter to delete the file.
