Random file creater, Batch-file - batch-file

Question

Im trying to make a batch-file that creates random directories and create files in the folders. But I am unable to make it work.
This is what I have tried:
#echo off
cd "%userprofile%\desktop\Safe_Space"
md "%random%"
md "%random%"
md "%random%"
cd "*"
copy /Y NUL %random%.txt >NUL

Answer 1

This will create 10 folders with random names and 1 file within each folder with random names.
This will create a completely empty file in the created directories:
#echo off
setlocal enabledelayedexpansion
for /l %%i in (1,1,10) do (
set tempf=!random!
mkdir !tempf!
copy /y NUL !tempf!\!random! >NUL
)
Increasing/Decreasing the 10 in for /l %%i in (1,1,10) do ( will increased the number of folders and files. To add more files to folders, repeat echo nul > %random.txt or simply create another loop to create multiple files in the folders.
fsutil is a another option, but requires admin privileges, it will create a nul variable in the file.
#echo off
setlocal enabledelayedexpansion
for /l %%i in (1,1,10) do (
set tempf=!random!
mkdir !tempf!
fsutil file createnew !tempf!\!random! 1
)
This creates a new file, with some text, in this case the word nul will be written to file, but you can change that:
#echo off
setlocal enabledelayedexpansion
for /l %%i in (1,1,10) do (
set tempf=!random!
mkdir !tempf!
echo nul > !tempf!\!random!
)

You can create directories and files by using FOR, RANDOM and basic instructions.
RANDOM create a random number between 0 and 32767. You can control the range of RANDOM using bottomlimit and upperlimit, e.g. 1-1000:
SET /a bottomlimit = 1
SET /a upperlimit = 1000
Don't forget to use SETLOCAL ENABLEDELAYEDEXPANSION (check How do SETLOCAL and ENABLEDELAYEDEXPANSION work?) and inside the loop the !VARIABLE! notation instead of %VARIABLE%. The following example creates 5 directories and 10 empty files. You can change these values as you like, using
FOR /l %%i in (1,1,10) instead of FOR /l %%i in (1,1,2) creates 2 directories.
FOR /l %%i in (1,1,10) means a loop starts at 1, steps by 1, and finishes at 10.
#echo off
SETLOCAL ENABLEDELAYEDEXPANSION
REM creating 5 directories...
FOR /l %%i in (1,1,5) DO (
SET dirName=!RANDOM!
REM create a directory with random name
MKDIR !dirName!
CD !dirName!
REM creating 10 files...
FOR /l %%i in (1,1,10) DO (
REM create an empty file with random name
COPY NUL !RANDOM!>NUL
)
CD ..
)
The instruction COPY NUL !RANDOM!>NUL doesn't require administation privileges
the >NUL eliminates unwanted output to console
