Import drive letters for use after reinstall?

Yes. It's a step on the way. I'd prefer this simpler check
:ProcessEachLine
If "%ThisLine:~0,13%"=="\DosDevices\%SystemDrive%" GoTo :EOF
to reduce by one the number of drive letters presented for user intervention.


Denis

that is easier, dont you want to get rid of the colon ?

set currentosletter=%systemdrive:~0,-1%

your original script
If "%ThisLine:~0,13%"=="\DosDevices\C" GoTo :EOF
If "%ThisLine:~0,13%"=="\DosDevices\D" GoTo :EOF
If "%ThisLine:~0,13%"=="\DosDevices\E" GoTo :EOF
If "%ThisLine:~0,13%"=="\DosDevices\F" GoTo :EOF
If "%ThisLine:~0,13%"=="\DosDevices\M" GoTo :EOF

could become

If "%ThisLine:~0,13%"=="\DosDevices\%currentosletter%" GoTo :EOF
If "%ThisLine:~0,13%"=="\DosDevices\D" GoTo :EOF
If "%ThisLine:~0,13%"=="\DosDevices\E" GoTo :EOF
If "%ThisLine:~0,13%"=="\DosDevices\F" GoTo :EOF
If "%ThisLine:~0,13%"=="\DosDevices\M" GoTo :EOF

"%ThisLine:~0,13%"
does not care about the colon. The variable ends one character before the colon.


All the best,

Oh, it's just occurred to me - when using that syntax to manipulate variables, the count starts at 0 not 1.
That's why "%ThisLine:~0,13%" does not include the colon.


All the best,
