With the Anniversary Update of Windows 10, you can finally abandon the 260 character maximum path limit in Windows. You just need to make a minor edit to the Windows Registry or Group Policy. Here’s how to make it happen.
Before Windows 95, Windows only allowed file names that were eight characters long, with a three character file extension–commonly known as an 8.3 filename. Windows 95 abandoned that to allow long file names, but still limited the maximum path length (which includes the full folder path and the file name) to 260 characters. That limit has been in place ever since. If you’ve ever run into this limit, most likely it was when you were trying to copy deep folder structures into other folders, such as when copying the contents of a hard drive to a folder on another drive. The Windows 10 Anniversary Update finally adds the option to abandon that maximum path length.
There is one caveat. This new setting won’t necessarily work with every application out there, but it will work with most. Specifically, any modern applications should be fine, as should all 64-bit applications. Older 32-bit applications need to be manifested in order to work, which really just means that the developer has indicated in the application’s manifest file that the application supports longer paths. Most popular 32-bit apps should experience no problem. Still, you don’t risk anything by trying the setting out. If an application doesn’t work, the only thing that will happen is that it won’t be able to open or save files that are saved in places where the full path exceeds 260 characters.
Home Users: Remove the 260 Character Path Limit by Editing the Registry
If you have a Windows Home edition, you will have to edit the Windows Registry to make these changes. You can also do it this way if you have Windows Pro or Enterprise, but feel more comfortable working in the Registry than Group Policy Editor. (If you have Pro or Enterprise, though, we recommend using the easier Group Policy Editor, as described in the next section.)
Standard warning: Registry Editor is a powerful tool and misusing it can render your system unstable or even inoperable. This is a pretty simple hack and as long as you stick to the instructions, you shouldn’t have any problems. That said, if you’ve never worked with it before, consider reading about how to use the Registry Editor before you get started. And definitely back up the Registry (and your computer!) before making changes.
To get started, open the Registry Editor by hitting Start and typing “regedit.” Press Enter to open Registry Editor and give it permission to make changes to your PC.
In the Registry Editor, use the left sidebar to navigate to the following key:
On the right, find a value named
LongPathsEnabled and double-click it. If you don’t see the value listed, you’ll need to create it by right-clicking the
FileSystem key, choosing New > DWORD (32-bit) Value, and then naming the new value
In the value’s properties window, change the value from 0 to 1 in the “Value data” box and then click OK.
You can now close Registry Editor and restart your computer (or sign out of your account and sign back on). If you ever want to reverse the changes, just head back to the
LongPathsEnabled value and set it from 1 back to 0.
Download Our One-Click Registry Hack
If you don’t feel like diving into the Registry yourself, we’ve created two downloadable registry hacks you can use. One hack removes the 260 character path limit and the other hack restores the default limit. Both are included in the following ZIP file. Double-click the one you want to use, click through the prompts, and then restart your computer.
These hacks are really just the
FileSystem key, stripped down to the
LongPathsEnabled value we described above, and then exported to a .REG file. Running the “Remove 260 Character Path Limit” hack sets the
LongPathsEnabled value to 1. Running the “Restore 260 Character Path Limit (Default)” hack sets the value back to 0. And if you enjoy fiddling with the Registry, it’s worth taking the time to learn how to make your own Registry hacks.
Pro and Enterprise Users: Remove the 260 Character Path Limit with the Local Group Policy Editor
If you’re using Windows 10 Pro or Enterprise, the easiest way to disable the new app install notifications is by using the Local Group Policy Editor. It’s a pretty powerful tool, so if you’ve never used it before, it’s worth taking some time to learn what it can do. Also, if you’re on a company network, do everyone a favor and check with your admin first. If your work computer is part of a domain, it’s also likely that it’s part of a domain group policy that will supersede the local group policy, anyway.
In Windows 10 Pro or Enterprise, hit Start, type gpedit.msc, and press Enter.
In the Local Group Policy Editor, in the left-hand pane, drill down to Computer Configuration > Administrative Templates > System > Filesystem. On the right, find the “Enable win32 long paths” item and double-click it.
In the properties window that opens, select the “Enabled” option and then click “OK.”
You can now exit the Local Group Policy Editor and restart your computer (or sign out and back in) to allow the changes to finish. If at any time you want to reverse the changes, just follow the same procedure and set that option back to “Disabled” or “Not Configured.”
The maximum path limit may not be something you’ve ever run into, but for some people it can certainly be the occasional frustration. Windows 10 has finally added the ability to remove that limit. You just have to make a quick change to the Registry or Group Policy to make it happen.
