Let’s take a look at a typical scenario whereby you can encounter this issue. You have a large Microsoft Word .docx file that’s stored in a Network shared folder and Word is running in the background. You open a new File Explorer window and you set Windows to display recent folders in Quick access. In this scenario, File Explorer stops responding for some time and then recovers. The duration of inactivity depends on the size of the .docx file, the content of the “recent files” list, and network latency. According to Microsoft, this issue occurs because File Explorer invokes the Microsoft Office Shell Extension to query for detailed information about the files that are in the “recent files” list. However, depending on network latency, Windows may receive requests to renew the content in the Quick access area while the Office Shell Extension is still querying the file contents. This causes File Explorer to restart the query. This extended activity can cause the File Explorer window to appear to freeze. This is especially true if the operation is prolonged by repeated queries of large files that are posted on the network.
Fix unresponsive Explorer due to large .docx file on Network share
To work around this issue, use one of either of the following 2 methods.
1] Make File Explorer open to “This PC”
You can make File Explorer open to This PC. This setting can also be changed by creating and configuring the following Registry key:
Before you begin, since this is a registry operation, it is recommended that you back up the registry or create a system restore point in case the procedure goes wrong. Once you have taken the necessary precautionary measures, you can proceed as follows:
Navigate or jump to the registry key below:
Then right-click on an empty space on the right pane.Select New > DWORD (32-bit) Value.Name the key launchTo.Double-click the newly created key and set the Value data to 1.Click OK.
2] Hide recent files and folders in “Quick access”
You can disable Quick Access. This setting can also be changed by creating and configuring the following Registry key:
Be sure to back up the registry or create a system restore point as described above and then proceed as follows:
Navigate or jump to the registry key below:
Then right-click on an empty space on the right pane.Select New > DWORD (32-bit) Value.Name the key ShowRecent.Double-click the newly created key and set the Value data to 0.Click OK.
And that’s it! I hope this resolves the unresponsive File Explorer issue for you.
