I wrote a very simple Batch file that directs output to a file. Here's the text body:

DATE /T > FileTreeList.txt
TIME /T >> FileTreeList.txt
cd >> FileTreeList.txt
tree /f /a >> FileTreeList.txt

When I run the Batch File in a directory that has a lot of folders and files, the output file (FileTreeList.txt) truncates at ~621KB. If I run the Batch File from command mode and direct output to a file, I get the same results. However, if I let the results display on screen, it shows all the results.

Why does it happen and how to fix it?

    Do you get the same results if you enclose all the commands in parentheses and only open FileTreeList.txt once for writing? `(date /t & time /t & cd & tree /f /a) >FileTreeList.txt` – rojo Aug 31 '15 at 21:05
  • Are you sure that the batch file with the 4 lines above runs with same privileges (= same user account) as when you run the last command manually from within a command prompt window with results output to window? This is important in case of traverse access permissions on all directories which could be an explanation for different tree lists. – Mofi Sep 01 '15 at 05:57
  • I tried your four lines in a batch file with switching current directory first to root of drive C: and writing the output of the four commands to `F:\Temp\FileTreeList.txt` on Windows 7 x64. The list file had 8.3 MB after batch file execution finished containing the entire tree. – Mofi Sep 01 '15 at 12:56

Probably your hard drive is full and only has a ~621KB of free space ;)

I guess that is the tree of the current folder. If you want a bigger file try going to %HOMEDRIVE% and list all the folders/files in the drive. Try this code:

@rem Turn the command line (C:>COMMAND before every command)
@echo off
rem Go to the homedrive (if not currently in)
if "%cd:~0,1%"=="%homedrive:~0,1%" call %homedrive:~0,1%:
rem go to the root of homedrive
cd %HOMEDRIVE%
rem execute your code
DATE /T > FileTreeList.txt
TIME /T >> FileTreeList.txt
cd >> FileTreeList.txt
tree /f /a >> FileTreeList.txt
