Windows 10: Broken/corrupted file?

I have a file I've been working on in MS Paint for a good few weeks. On the 23rd, I saved it before shutting my computer down, and once I came back on, I noticed I couldn't open the file on MS Paint. It said "Paint cannot read this file. This is not a valid bitmap file, or its format is currently not supported." It's a PNG. I tried opening it in photos, and I got a similar message, "It looks like we don't support this file format." I tried opening it on onedrive, and it was the same. I can't seem to open it anywhere. The file in question is 1,998 KB in size. I didn't have file restoration on, unfortunately, so I don't quite know what to do.

Corrupted file RAR

If the archive has been created using WinRAR, why don't you try WinRAR itself? It has a built-in repair feature for repairing corrupted archive (ZIP as well as RAR). Follow the steps given below:

• Open WinRAR application in your system.
• Now click on File tab > Open or simply press Ctrl+O.
• A small window "Find Archive" will pop up. Locate the corrupt RAR archive from your system directory and select it.
• Now click Open button.
• Click Tools tab > Repair archive or simply press Alt+R.
• Again a small window "Repairing File name.rar" will pop up.
• Now click Browse to select a location to save the repaired archive.
• Check the box "Treat the corrupt archive as RAR" and click OK.
• WinRAR will start repairing of corrupt RAR archive. Once it gets completed click Close.

I hope the above steps will help you repair the corrupted RAR archive.

Thanks.

Please perform the below steps and see if it helps to resolve the issue.

This issue may happen due to system file corruption. I suggest you to run System file checker. System File checker (SFC) scan is done to check if there are any corrupted system files that could be causing this issue. Kindly follow
the below given steps:

• Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt.
• In Command prompt type sfc/scannow and press enter.
• Restart the computer.

If no corrupted system files were found in the previous state, then I suggest you to try the following steps:

• Open command prompt by pressing Windows key + X and selecting “Command prompt admin”.
• In command prompt, type the following commands and press Enter after each command:

DISM.exe /Online /Cleanup-image /Scanhealth

DISM.exe /Online /Cleanup-image /Restorehealth

• Close the command prompt and restart the PC and check if it works.

Hope this information helps. Please post us if you need any further assistance with Windows.
