Hi there,
I have 3 directories on c:drive: folde1, folde2 and folder, which each folder has different funktion.
a.exe will run succesfull if "folder" name exist.

If I want to test folde1
rename c:\folder folder3
clear
rename c:\folde1 folder
echo -- run a.exe --
a.exe

After test folde1, let say I want to test folde2
rename c:\folder (back to ORIGINAL name) folde1
clear
rename c:\folde2 folder
echo -- run a.exe --
a.exe

and so on
Every time I have to look C:drive where I am now:
folder from folde1 or
folder from folde2 or
folder from folde3

Is possible to make it automatic and create batch file "autoexec.bat"?

Any help?
thanks
If I understand correctly, you are typing those commands into command prompt and wish to create a batch file to automatically run (at what time?)

I don't recognize 'clear'
To check if a folder exists you want to use 'if exist FolderName Command'
To check if a folder does not exist you use 'if not exist FolderName Command'

so if you want to check if a folder named "Folde1" exists, and execute a.exe only if the folder is there, you would have something like:
'if exist Folde1 start a.exe'


If you want it to run on startup, place a shortcut into the startup folder
In Windows 7: (%appdata%\Microsoft\Windows\Start Menu\Programs\Startup)@Lemonilla
Thanks for the quick response.

It is only msdos that run in ram memory booted from FLASH drive.
All the files & directories are inside the flash drive (Nothing to do with internal HD or windows system).
I am trying to reduce the problems and just limit of 2 directories only:
folder and folde1
This is my logical thinking for autoexec.bat, it will work but I dont know how to write the script in msdos.

==>Boot dos to test folde1:
if c:\folde2 exist
do c:\a.exe
else
rename c:\folder folde2
clear
rename c:\folde1 folder
do c:\a.exe

==>boot dos to test folder:
if c:\folde1 exist
do c:\a.exe
else
rename c:\folder folde1
clear
rename c:\folde2 folder
do c:\a.exe

What do you think, is it possible to create autoexec.bat?
ThanksWhat version of MSDOS is it? In MSDOS you cannot rename directories.

Explain what you want to do (not what commands you think will work).@foxidrive
DOS version 4.10.2222
This is my autoexec.bat tested and worked ok, but I dont know how to make if condition(s) script work:

rename c:\folder folde2
clear
rename c:\folde1 folder
clear
c:\a.exe

ThxThis should let you rotate the folders - is that what you want to do?

I don't know what 'clear' does. The screen clear command is CLS

Code: [Select]@echo off
rename c:\folde abc
rename c:\folder1 folde
rename c:\folder2 folder1
rename c:\folder3 folder2
rename c:\abc folder3
c:\a.exe
Thank you very much for your help.
Without your idea may my batch file never work.

It works fine on my test.

DOS doesnt support a file BIGGER than 4 Gb.
NTFS4DOS can read/write on NTFS, but it can not be automatic, because every time I have to type "yes" to agree and punch enter. Is there a magic program to make it automatic? or MAYBE you know similar freeware tools like ntfs4dos?

Thank you very much!
This sort of thing works in some cases. Assuming you are typing the whole word 'yes'

echo yes|ntfsdos commands

or
echo yes>yes.txt
ntfsdos commands del yes.txt@foxidrive
Ntfs4dos can not be use for my build. There is c: drive, but no file found.
Thanks for your script, hope I can use it one day.
