Long Directory/File Names In Windows (Media File Scanner)

dt logo 1.5inchWhen using Media File Scanner, many sources will have directories and file names that exceed Windows' 260 character default limit.  If you are targetting an NTFS, or other Windows drive, you will need to enable long directory and file name paths in the Windows permissions.  This limit is to preserve compatibility with older, and MS-DOS, programs.  If you need that compatibility, you may want to target a NAS as the Media File Scanner output, which will support long directory/file names natively.

Enabling Long File/Dir Names In Windows

Please note: Windows 10 - 1803 build or greater is required for long file/dir name support

To enable it:

  1. Click the Windows key and type gpedit.msc, then press the Enter key. This launches the Local Group Policy Editor.
  2. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > System > Filesystem. FileSystemEnableWin32LongPaths
  3. Double click "Enable Win32 long paths" and change it from "Not configured" to "Enabled"
  4. Reboot the machine for the change to take effect

Now your Windows drivers should support directories of up to 65535 characters in length, which is far more than the internet/nas/smb/nfs standard of 4096.
