If you’re a core Windows user for long, you might as well be aware that any device driver that you install on your underlying Windows OS is stored in a system folder named “DriverStore”. It is a collection of trusted device drivers packages from third-party sources. This collection is used to validate which drivers can be installed on your computer. In this post, we are going to review a freebie – DriveStore Explorer, which helps you manage, list, add or remove the device drivers installed on your PC.
DriverStore Explorer is a free software that lets you manage, list add, or remove device driver packages in DriverStore folder of Windows.
Driver Package and INF File
If any device driver needs to be installed on a PC, it has to have its driver package files copied in DriverStore. When we add any driver package in DriverStore, all of its files are copied along with one INF File which actually references all the other files present in the package. As every single one of these files is crucial for driver installation, INF file must reference all the files that are present in the package, so that during installation these can be found easily in DriverStore. In the other way round, if INF file references a file that’s not available in the package, it is not copied to the DriverStore.
Copying the files related to a driver package to DriverStore is called Staging. In order to install a driver for any device on a PC, it must be staged in DriverStore i.e. all the corresponding package files, along with INF File must be copied to DriverStore. However, you can’t just pick any driver package and copy it to DriverStore. It needs to go through a couple of integrity and syntax checks before the files are copied. Below are the brief stages during staging:
- Verification: Before the driver package is copied to DriverStore, it is verified against several security checks which confirm whether or not the package files are corrupted or tampered with. The driver package should be digitally signed in order to pass through this check.
- Validation: This is the next part where the user permissions are validated and INF file is checked for all the referenced files in the package. In case any discrepancy is found, the package shall not be copied.
Using DriverStore Explorer
Once you have downloaded DriverStore Explorer, extract the files and run the executable (Rapr.exe) with administrator privileges.
The DriverStore Explorer window will open right away on your screen. Click Enumerate to list all the copied (and installed) driver packages in DriverStore location. Once all the Driver Package details are listed, you can choose to (force) delete any zombie driver that might potentially be creating a problem.
Also, if you have a package available, you can copy its files to DriverStore using Explorer window. Just click Add Package and select the package files to import. Apart from this, you can also export package files from DriverStore Explorer. Right-click any driver entry and select Export to save it to your local disk.
That’s pretty much about it. It is indeed a decent tool to add or remove any driver packages from your system. Old drivers keep sitting in the system consuming memory and resources so this can come quite in handy to get rid of them.
