I am looking to just rename *.jpg files to a fixed length. They all need to be 7 left of .jpg?
Can your example pad script be modified to do that easily?
Examples:
1234567.jpg ok already.
123456.jpg needs to be 0123456.jpg
And of course they could start with 26.jpg (one or more numbers left of jpg) for example 0000026.jpg

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= echo !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

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.

Since I am just learning how to write .bat files for my Windows2000 Computers,
