In Windows Command Prompt (CMD), you can use the dir command to search for files in a specific directory. Additionally, you can use various parameters and operators to refine your search. Here are some common examples:

1. Basic File Search: To search for files in the current directory, simply open the Command Prompt and use the dir command:

    dir
   

2. Search in a Specific Directory: To search in a specific directory, specify the path after the dir command:

    dir C:\Path\To\Directory
   

3. Search for a Specific File: To search for a file with a specific name, use the /b parameter along with the filename:

    dir /b filename.txt
   

   This will only display the filenames that match your search criteria.

4. Search for Files with a Specific Extension: To search for files with a specific file extension, use the *.extension wildcard:

    dir *.txt
   

   This will list all files with a .txt extension.

5. Search for Files in Subdirectories: To search for files in subdirectories as well, use the /s parameter:

    dir /s /b filename.txt
   

   This will search for filename.txt in the current directory and all of its subdirectories.

6. Search for Files by Date: You can search for files created or modified within a specific date range using the /tc (creation time) or /tw (last write time) parameters. For example, to find files modified within the last 7 days:

    dir /s /b /tw /a-d /od /t:c-7
   

   This command will search for files modified within the last 7 days, starting from the current directory and its subdirectories, and list them in order of creation time.

7. Search for Files by Size: To search for files of a specific size, you can use the /s and /b parameters along with the > or < operators. For example, to find files larger than 1 MB:

    dir /s /b /a-d C:\Path\To\Directory\*.* | findstr /r /c:"^[0-9][0-9]*.*[1-9]..*MB"
   

   This command searches for files larger than 1 MB in the specified directory and its subdirectories.

These are some common ways to search for files using the Windows Command Prompt (cmd.exe). Adjust the parameters and operators to suit your specific search criteria.
