QCAT ISF to PCAP

I heard there was a way to convert an ISF file to PCAP using QCAT by command line but I've not found a way to do so with anything I've read or searched for on the internet.
Anyone know of how to perform this action?
Thanks
From a short Qualcomm slide show:
QCAT runs cmd line to generate the PCAP/TXT. Customer can run cmd line option to generate PCAP/TXT
Executable: C:\Program Files (x86)\Qualcomm\QCAT 6.x\Bin\PCAP Generator.exe Usage: PCAP Generator.exe [input_file] [output_path] [-option]
This command converts a file or directory of .qmdl files into a single .hdf file. The .hdf file will be named the same as the original log file or the directory of the input but with a .hdf extension.
QCAT –hdf file
or
QCAT –hdf directory

Using command line to compress a .bak file and moving the zip file

I am trying to use command line to zip a .bak file then cut the zip file to another location or copy/paste and delete the original once the copy is complete.
Right now my script is
copy "\\a\*.bak" "\\b"
I would like to compress the .bak file (in folder a) as it is a huge file, and then CUT the zip file into folder b.
Windows has a built-in functionality for this.
tar.exe -a -c -f file_Output.zip your_file.bak
file_Output.zip will be the file you will get as your zipped file, your_file.bak will be the file you are trying to compress.

How to copy files throuth a windows command line?

I want to copy many text files from one folder to another. The file names are contained in another text file. So the commands should be able to read in the file names and do the copy things. I can do this with R but it's very slow. I wonder if it's possible to do this with the command line? (I can copy single file with the command line, but don't know how to copy many with for or while loop or something.) Thanks in advance.
I found this question helpful: How do you loop through each line in a text file using a windows batch file?
This is what you need to just paste into the command line. If you want to save it in a bash file you need to use %% instead of % for variables.
for /F "tokens=*" %a in (myfile.txt) do copy "%a" "new folder\%a"
This simply loops through the file, and for each line does a copy of it to the new folder. The quotes are important in case of spaces in the filenames.

Create a batch file to copy and rename file

I need to write a batch file that copies a file to a new folder and renames it.
At the moment, my batch file consists of only this command:
COPY ABC.PDF \\Documents
As you can see, it only copies the file ABC.pdf to the network folder Documents.
However I need to change this so it renames the file ABCxxx.pdf, where xxx is a text variable that I would like to set somewhere in the batch file.
For example, if xxx = _Draft, then file would be renamed ABC_Draft.pdf after it is copied.
Make a bat file with the following in it:
copy /y C:\temp\log1k.txt C:\temp\log1k_copied.txt
However, I think there are issues if there are spaces in your directory names. Notice this was copied to the same directory, but that doesn't matter. If you want to see how it runs, make another bat file that calls the first and outputs to a log:
C:\temp\test.bat > C:\temp\test.log
(assuming the first bat file was called test.bat and was located in that directory)
type C:\temp\test.bat>C:\temp\test.log
