Able to find directory with 8dot3 naming convention but not files

Do you get any error message when you use Dir command with 7ZAEXE~1.BAT short name?

Are you running the batch script or Command Prompt as a administrator?

What happens when you execute below command?

Code:

Dir  C:\PROGRA~1

Lets also repair any NTFS file system errors.

Please open the Command Prompt by typing cmd.exe into Start Menu, right-click on Cmd.exe, and open it as an administrator.

Execute below command:

Code:

Chkdsk  C:  \f

I get the directory listing when I do dir c:\progra~1.

That means there is a problem with 7ZAEXE~1.BAT short name.

Also execute Chkdsk tool maybe its a file system error.

The file is there though:

C:\Users\xxx09c>dir /X C:\Users\xxx09c\AppData\Local\Temp\CCS_78~1\util\
Volume in drive C is Windows
Volume Serial Number is
Directory of C:\Users\xx09c\AppData\Local\Temp\CCS_78~1\util
02/02/2018 02:16 PM <DIR> .
02/02/2018 02:16 PM <DIR> ..
02/02/2018 11:01 AM 274 7ZAEXE~1.BAT 7zaexemy.bat

Does Dir command give you error message when you use the 7ZAEXE~1.BAT short name?

Also try Type command to see if it gives you error message.

Code:

Type  C:\Users\xxx09c\AppData\Local\Temp\CCS_78~1\util\7ZAEXE~1.BAT

Can you also make sure 7ZAEXE~1.BAT batch file is not been blocked by your antivirus program.

Yes, dir does not find the file with the short name. It's not being blocked by the antivirus program either.

There is no Windows 10 setting that is disabled blocking your access to that file using short name of the file. If there was such a Windows 10 setting that is disabled then you should also not able to use Dir PROGRA~1 command which you can without error.

Ok. I will let you know if the chkdsk helps. Thank you.

You are very welcome!
