Ever since Windows 95, Microsoft has only allowed file paths up to 260 characters (which, to be fair, was much nicer than the 8 character limit previously). Now, with a registry tweak, you can exceed that amount in Windows 10.
As pointed out by the How-To Geek, to enable long file paths, you’ll need to edit the registry. Start by following these steps:
Open the Start menu and type “regedit.” Launch the application.
Navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystemRight-click the value “LongPathsEnabled” and select Modify.
Change “Value data” from 0 to 1.
Click OK.
Now you’ll be able to use much, much longer file paths. The one caveat is this may cause some compatibility problems with older 32-bit applications. If you don’t use anymore 32-bit software or simply have a strong need for very long file paths, this tweak should help you.
