# Why Windows Shows ERROR_FILE_NOT_FOUND—and What to Do Next? Windows errors can be confusing, especially when a simple message such as ERROR_FILE_NOT_FOUND appears without explaining what went wrong. One of the most common codes associated with this message is 0x80070002. The error essentially means that Windows or an application tried to access a file but could not find it at the expected location. The missing file may belong to Windows, an installed application, an update, a driver, or another system process. WHAT DOES ERROR_FILE_NOT_FOUND MEAN? ERROR_FILE_NOT_FOUND is a Windows error condition indicating that a requested file could not be found. A common associated error code is: Error Code Meaning What It Indicates 0x80070002 ERROR_FILE_NOT_FOUND Windows cannot find a required file 0x80070003 ERROR_PATH_NOT_FOUND Windows cannot find the specified path WHY DOES WINDOWS SHOW ERROR_FILE_NOT_FOUND? Several situations can cause the error. Possible Cause What Happens Missing file A required file was deleted or moved Corrupted system files Windows components are damaged Failed Windows Update Update files are incomplete or corrupted Incorrect file path Software points to a location that no longer exists Application corruption Program files are missing or damaged Driver problems A required driver component cannot be located Scheduled task A task references a deleted executable Storage changes Files were moved between drives or folders Identifying when the error occurs is one of the most useful ways to narrow down the cause. -------------------------------------------------------------------------------- When Does ERROR_FILE_NOT_FOUND Usually Appear? The error may appear in different circumstances. DURING WINDOWS UPDATE If the message appears while Windows is downloading or installing an update, the problem may involve damaged or incomplete update files. WHEN OPENING AN APPLICATION If only one application produces the error, its installation may contain missing or corrupted files. DURING STARTUP An application, service, or scheduled task may be trying to launch a file that has been removed. DURING FILE OPERATIONS Moving, opening, copying, or accessing files can trigger the error if Windows is given an invalid or unavailable path. -------------------------------------------------------------------------------- What to Do When ERROR_FILE_NOT_FOUND Appears 1. RESTART WINDOWS Start with the simplest troubleshooting step. Save your work, select Start → Power → Restart, and then try the operation again. If the error was caused by a temporary process or file-access problem, a restart may resolve it. -------------------------------------------------------------------------------- 2. IDENTIFY THE MISSING FILE If the error message provides a filename or path, examine it carefully. For example, an application might indicate that it cannot find a file inside: C:\Program Files\ExampleApp\ Open File Explorer and check whether the referenced file exists. If it does not, determine which application or Windows component owns the file before attempting to replace it. Avoid downloading individual DLL or EXE files from random websites. Replacing a system file with an untrusted copy can create additional security and compatibility problems. -------------------------------------------------------------------------------- 3. Run System File Checker If you suspect damaged Windows system files, Microsoft's built-in System File Checker can scan protected system files. Open Command Prompt as administrator and run: sfc /scannow Wait until the scan completes. If SFC reports that it repaired files, restart Windows and check whether the error has disappeared. -------------------------------------------------------------------------------- 4. Use DISM to Repair Windows Components If SFC cannot resolve the problem, the Windows component store itself may need repair. Open an administrator Command Prompt and run: DISM /Online /Cleanup-Image /RestoreHealth After DISM finishes, run: sfc /scannow Then restart the computer. This combination can help when Windows system components are damaged. -------------------------------------------------------------------------------- 5. Check Windows Update If ERROR_FILE_NOT_FOUND appears during an update, open: Settings → System → Troubleshoot → Other troubleshooters → Windows Update Run the Windows Update troubleshooter if it is available for your version of Windows. Also check that: * Windows has enough free storage. * Your internet connection is working. * The computer has been restarted. * The update is not being interrupted by another system process. -------------------------------------------------------------------------------- 6. Repair the Affected Application If the error occurs only with one program, Windows itself may not be the primary cause. Depending on the application, you may be able to repair it through: Settings → Apps → Installed apps → [Application] → Advanced options If a Repair option is available, try it first. If repairing does not work, reinstall the application using its official installer. -------------------------------------------------------------------------------- 7. Check Scheduled Tasks A deleted application can sometimes leave behind a scheduled task that still attempts to run its executable. Press Windows + R, enter: taskschd.msc and press Enter. Review Task Scheduler Library for tasks associated with the software that is generating the error. Look at the Actions section to see which executable or script the task is trying to launch. Do not remove system tasks unless you are certain they are unnecessary. -------------------------------------------------------------------------------- 8. Look at Event Viewer If the error does not clearly identify its source, Event Viewer can provide additional information. Open: Event Viewer → Windows Logs → Application and: Event Viewer → Windows Logs → System Look for errors recorded around the time the problem occurred. Pay particular attention to: * Application names * File paths * Service names * Error codes * Timestamps This information can help identify the component looking for the missing file. -------------------------------------------------------------------------------- 9. Consider Recent Changes Think about what changed immediately before the error appeared. Recent Change What to Investigate Installed an application Repair or reinstall it Uninstalled software Check for leftover scheduled tasks Installed a driver Check the driver installation Windows Update Troubleshoot Windows Update Moved files Verify the original path Changed drive letters Check application paths Used cleanup software Check whether required files were removed This can often point toward the underlying cause more quickly than trying random fixes. -------------------------------------------------------------------------------- ERROR_FILE_NOT_FOUND vs. PATH_NOT_FOUND The two messages are closely related but aren't identical. Error Code Meaning ERROR_FILE_NOT_FOUND 0x80070002 The requested file cannot be found ERROR_PATH_NOT_FOUND 0x80070003 The requested directory/path cannot be found For example, if Windows expects: C:\Apps\Example\program.exe but program.exe is missing, the situation can correspond to 0x80070002. If the Example directory itself cannot be found, the problem may correspond to 0x80070003. -------------------------------------------------------------------------------- Quick Fix Checklist Use this checklist when you encounter the error: Step Action 1 Restart Windows 2 Read the complete error message 3 Check the referenced file/path 4 Run sfc /scannow 5 Run DISM /Online /Cleanup-Image /RestoreHealth 6 Check Windows Update if the error occurs during updating 7 Repair or reinstall the affected application 8 Check Task Scheduler 9 Review Event Viewer 10 Investigate recent software, driver, or system changes FINAL THOUGHTS ERROR_FILE_NOT_FOUND doesn't necessarily mean that Windows itself is broken. It means that a process expected to find a particular file but couldn't locate it. The most important first step is therefore to determine which application or Windows component is requesting the missing file. Once you know that, the appropriate fix—repairing system files, troubleshooting Windows Update, repairing an application, or correcting a file path—becomes much clearer.
