Just open the Windows PowerShell, then navigate to your proxy folder,
and run those two lines.
Get-ChildItem -Filter “*LRV” | Rename-Item -NewName {$_.name -replace ‘LRV’,’MOV’ }
Get-ChildItem -Filter “GL*” | Rename-Item -NewName {$_.name -replace ‘GL’,’GX’ }
For DaVinci the HighRes file has the same name as the Proxy file. Once you have it renamed, you can link the proxy files within DaVinci Resolve to the HighRes ones.
