SHRINK C VOLUME TO SMALLER CAPACITY

Hi,

Thanks for replying to us with the status of your issue.

While shrinking the volume, you cannot use the upper arrow because, while shrinking the system will take the max amount of space that can be shrink. However, you can use the down arrow button to reduce the amount of space, which you want to shrink.

Since, both up and down buttons are not working, it might be an issue with system file corruption.

I suggest you to try running System File Checker (SFC)
and check if it helps.

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

To perform SFC Scan, refer to the below link:

Note: Steps mentioned for Windows 8/8.1, will work fine with Windows 10.

Hope it helps, reply to us with the status of your issue. We will be happy to assist you.

 

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.

If the issue persists, follow method 2.

Method 3: Perform SFC scan

I would suggest you to perform SFC scan and check if that helps. The
sfc/scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. It is a utility in Windows that allows users to scan for corruptions in Windows system files and restore
corrupted files.

Refer the link: Use the System File Checker tool to repair missing or corrupted
system files
