This post has two batch scripts:
1. Batch script to rename files with zero padded number series-prefix
2. Batch script to remove prefix of perticular length
1. Batch script to rename files with zero padded number series-prefix
This script will accept file-type to be searched and lenght of zero-padded prefix to be attached.

Consider you have to rename / arrange a lot of mp3 files in a perticular sequence:
File names before execution:

Command on dos prompt: RenZeroPad.bat mp3 4
File names with attached prefix:
0001 fileX.mp3

0003 fileZ.mp3
The Batch Script to add zero pad digits prefix:
@echo off
setLocal EnableDelayedExpansion
set /a cnt=1
for %%i in (*.%1) do (
call :Set0Pad %2
set newName=!str! %%i
ren “%%i” “!newName!”
)
:Set0Pad
set padcntr=0000000000%cnt%
set str=%padcntr:~-%1%
set renstr=%str%
set /a cnt+=1

I need to create an batch file that will
rename a file on my F: drive
named MyBackup 00001.qic
to MyBackup nnnnn.qic (nnnnn = next available file number).
For example if files exist:
MyBackup 00002.qic
MyBackup 00003.qic
MyBackup 00004.qic
MyBackup 00005.qic
then rename MyBackup 00001.qic to MyBackup 00006.qic
Yes, the file names always have a space just before the 5 digit number.

You may read from and write to a file to remember last file name using batch script.
Create a counter.txt to store the last variable value
As per my script use following line to assign last counter value.
set /p cnt=
After you're done with renaming reset the value in counter.txt as follows:
echo !cnt!>counter.txt
Consider this:-
Step 1: Create counter.txt in same directory of script.
step 2: Use below script updated to read counter value from a text file and rename from that number.
@echo off
setLocal EnableDelayedExpansion
:: set /a cnt=1
set /p cnt=
for %%i in (*.%1) do (
call :Set0Pad %2
set newName=!str! %%i
ren "%%i" "!newName!"
echo !cnt!>counter.txt
)
:Set0Pad
set padcntr=0000000000%cnt%
set str=!padcntr:~-%1!
set renstr=%str%
set /a cnt+=1
