I have multiple text files that contains 3 lines of information that I want to output as one single line for each file

Example

**File1.txt** contains

```
User: "John"
Date: "13-March-2017"
Time: "10.30am"
Remarks: "xcvsfas"

```

**File2.txt** contains

```
User: "Mary"
Date: "13-March-2017"
Time: "11.30am"
Remarks: "xerteyas"

```

My expected output is as follows

```
c:\temp\file1.txt:User: "John"; Date: "13-March-2017"; Time: "10.30am"
c:\temp\file2.txt:User: "Mary"; Date: "13-March-2017"; Time: "11.30am"

```

I tried
`findstr /s /i "user date time:" %inputfolder%\*.* > %outputfolder%\final.txt`
