Hello Experts,

I need a help I've a batch script for folder locking, in this script I've set a password for folder access after that I convert this batch to exe & give it to users.
Now user wants to create own password & after creating the password once user put password for folder access it should not be appear it should be in form in dot or blank.
Most important thing i want set a default password in case users forget password in that case admin should open that folder from default password, also main folder, sub folder & files which is store in Vault folder should not be find if anyone try to find using windows search.

This is a follow-up to another thread located here:

Create an executable file to open a non-executable file

In that thread, expert Joe Winograd provided a solution which involves creating an AutoHotkey (ahk) "Run" command (which I know how to do) then compiling the resulting .ahk file to create an .exe file. That was a great solution and I'm glad to now know how to do that. However, since closing the previous thread, I've realized that that solution is not practical for the specific purpose* that prompted my question.

As a result, I'm back to my original question which is:

How do you directly create an executable file (.exe or .cmd) to open a non-executable file (.xlsm, .txt, .ahk, etc)?

In the previous thread, expert tuvi suggested putting the following in a .cmd file:

start C:\Users\UserName\FolderName\FileName.xlsm

Open in new window

Unfortunately, while I know how to place a command in the cmd/prompt/DOS window (not sure what it's called), I do not know how to create a .cmd or .exe file. I tried simply pasting the above line in a Notepad window then saving it, first with a .cmd extension and then with an .exe extension but neither of those worked.

It seems like something I should know how to do but that's why I'm happy all of you great experts are available to answer questions. :)

Chemo has taken a lot from me. I am having problem with a batch file and have gone back to square 1 to test simple things.


Why am I getting a syntax error?
Have a user that started saving long file names and folders creating problems on a 2012 Server. File path has exceeded 280+ in length luckily there are only 5 folders affected. Problem is I created a virtual directory to the folder using Subst command, however I get this error when I try to rename it.
subst error
I tried Subst in administrator mode but the drive doesn't show, a known issue.
I tried without administrator mode and the mapped drive shows however I get the above error.
Downloaded the gui interface get the same error above.
Hello Experts,

I am trying to run as administrator a .bat file on a Windows 10 virtual machine remotely via VirtualBox's command line interface. I am controlling the Windows 10 virtual machine via a Linux headless server.

Currently I am using the command:

vboxmanage guestcontrol "win10clean" exec --image "C:/Temp/run.bat" --username localadmin --password *** --verbose --wait-stdout


Opening guest session as user 'localadmin' ...
Waiting for guest session to start ...
Guest session (ID 13) has been started
Starting guest process ...
Process 'C:/Temp/run.bat' (PID 4592) started

C:\WINDOWS\system32>REG ADD HKLM\Software\Microsoft\Windows\currentversion\explorer\advanced /v Start_PowerButtonAction /t REG_DWORD /d 2 Process terminated
Exit code=1 (Status=500 [successfully terminated])
Closing guest session ...

The VM name is win10clean
The .bat file is called run.bat and is stored on the VM under the path C:/Temp/
The run.bat file is suppose to update a registry value which is why the command must be run as administrator. However the registry value says the same.

Please let me know how to add SharePoint login credentials in below code.

pushd "%SOURCE_DIR%"

for %%F in (%FILENAMES_TO_COPY%) do (

    for %%D in (%DEST_DIRS%) do (
        echo file "%%~F" to "%%~D"
        xcopy /Y "%%~F" "%%~D"



echo. Done.
exit /b

Really appreciate any suggestions on this.

I have some reports (MS excel Spreadsheets) on my folder on C drive. I have created a module in MS Access 2013 database. This module can be called using AutoExec macro. Basically I have created some scripts which will run a query and export the result into different excel files and then do the formatting. I need to transfer those excel files into SharePoint on daily basis. SharePoint is password protected. I am trying to automate the process. I use windows 7 OS, Office 2013. I am looking for a vba code/scrip or MS DOS/batch to do this work for me.

On SharePoint, there are some files already exist. I don't want to delete those files while I run script to transfer my reports into SharePoint.

Any support on this would be greatly appreciated.

g:\ace\<create current date folder>\

k:\rule\<create current date folder>\

Please suggest this process how to done from batch script, after complete this task log (.txt or .csv) should be generated ?

Good day gentlemen (and any ladies that may also be present among us).

I have a cracking challenge that will tease your expertise.

I have titled this challenge '31' because it is based on a simple game I played as a child.

The game starts with a running total of 0. Two players take turns choosing a number between '1' and '6' which is added to the total. The player who chooses the number which brings the total to '31' wins.

The numbers '1' to '6' are chosen from a pool of four '1's, four '2's, four '3's, four '4's, four '5's and four '6's. Once a number is chosen, it is removed from the pool of available numbers.


Total = 0

Let's say we have the following numbers available:


Player A chooses say, 5.

Total = 5 (because 0 + 5 = 5)

A '5' is removed from the pool of available numbers so we now have:


(Notice there are now only 3 '5's in the pool)

Let's say player B chooses '4'

Total = 9 (because 5 + 4 = 9)

And our number pool now looks like the following:


If any set of numbers '1' through '6' is exhausted then that number cannot be chosen in subsequent turns.

Programming Considerations

The program must be written using only DOS commands as a .BAT or .CMD
Need solution in UNIX for below scenario.

I have a folder like /desktop/user/folder with the below files in it. I want the count of the files after removing the timestamp from the files.
Need more of a generic solution which can handle any timestamp format and file format.


Expected Result:
test_file1    2
test_file2    3
Hi, I did some WMI troubleshooting on a Win10 Pro that was having trouble with the SCCM client installation.
After running the WMIDiag.vbs script from the WMI Diagnosis Utility 2.2 DL link (, I ran this on an elevated command prompt:

dir /b *.mof *.mfl | findstr /v /i uninstall > moflist.txt & for /F %s in (moflist.txt) do mofcomp %s

I didn't notice that I was currently in the C:\Windows\System32 directory instead of a level deeper, in wbem. My bad.
I got the following output:

C:\Windows\System32>dir /b *.mof *.mfl | findstr /v /i uninstall > moflist.txt & for /F %s in (moflist.txt) do mofcomp %s

I have a macro express pro app that I want to keep running in the background when my computer is on. For some reason, it stops functioning and terminates. But I don't know that until I go to call it up and I have to restart it. Also, it supposed to run at startup, but maybe windows doesn't like it, so it does not start with the other apps at startup. How do I use the task scheduler to make sure it starts at startup and also to check that it is running and if it is not running to relaunch it. the default path to the app is "C:\Program Files (x86)\Macro Express Pro\MacExp.exe" default directory is "C:\Program Files (x86)\Macro Express Pro"
Hi Experts,

We are changing our servers to virtual servers, and for protection sake our IT doesn't want map drives to our data server, therefore for getting access I would need to type \\MyServerName and this would always prompt me for a user name and password.

How do I program these settings in Access?

Also we currently have some data residing in SQL. and currently have DSN files storing all connection info, and in Access linked table manager we just point to that DSN.

How will all these get accomplish w/o saving a DSN locally?
 I try to use the command line with the pageant.exe tool.
 The goal is to bypass any question related to my password.
 I know the pageant.exe; it works very weel with the putty.exe and plink.exe.
 What is the exact syntax for the command line ?

 I try the 2 command without success :

 winscp.exe /ini=nul sftp://root@hostname /privatekey=path\file.ppk /script=path2\command_script.cmd /log=path3\log_file.log

 winscp.exe /ini=nul /script=path2\command_script.cmd

 ...considering that the "command_script.cmd" include the path for the SSH Key (ppk), starting by a "open" Again, the script ask me to provide the user Root password. It seems that it doesn't recognize the PAGENT process

Most of my work involves video editing.
The folders (Dir) where I keep originals, copies, pre/post-edit files and so forth are all set with the following "sort" attributes (columns):
Name - Length - Size - Frame Width - Frame Height - Data Rate

For each new folder I create or Copy/Move I have to redo all these attributes again, specially when I copy a folder since it always seems to default back to:
Name- Date Modified - Type - Size or similar values.

You can imagine the amount of time & effort required to do this for all new or copied folders..
I've tried every conceivable syntax with Robocopy and cant get it to work for these reasons:
1. When I open CMD it defaults to the current User, which does have Admin rights, but I can't get Robocopy to work with the "COPYALL" or any other syntax other than "\e" and that only gives me a copied Dir/sub-Dir again with default values..
2. When I open CMD and "Run as Admin" it goes to C:\ .. which is fine, except the DIR Im trying to copy shows as "Cannot find path specified" ..

The main Dir Im trying to work with is located:
C:\Users\AV Masters\Video\Edits
I created 2 test folders (DIRS) under \AV Masters\ .. called AVTEST1 and AVTEST2
AVTEST1 contains a sub-Dir named "AV" which contains some sample videos to test this copy process..

What I'm trying to accomplish:
Create one main folder (Dir) with a sub-Dir that contains the video files I want..
Whenever I need to create a new folder/Dir somewhere or copy an …
No comments, but we're still running WordStar v.7 as our main word processor. We operate the 32-bit version of Windows 10, and we physically print letters from WordStar via a PCL driver (mapped to shared Windows printers). This works fine with all of our printers except one - our Canon iR4570 copier.

Our main copier has just gone to the wall, so we're down to only one LaserJet that can carry out this function. Obviously I want a bit more redudency than this.

We run Wordstar as a legacy app through the ntvdm.exe process we've installed with Windows 10 32-bit. If I send a print job via PCL to the iR4570 it generally never prints anything, and the touch-screen concole becomes unusable. It is like it is running a corrupt process that is consuming all memory and/or CPU cycles . The only way to recover is to physically switch the iR4570 off.

On very rare occasions, it does start printing, but just junk text comes out - either filing the page, or just a couple of letters at the top of each page. It'll print until the trays are empty.

If I print to the iR4570 via PostScript from Wordstar, it is absolutely fine. HOWEVER, PostScript fonts are slightly bolder, and it doesn't look quite right for our requirements.

The iR4570 has a pretty much identical firmware to our other copier that went to wall, and which handled this all fine with PCL printing, day in day out, until it's demise. I'm hopeful there is something just not right in the settings I can flush out - but before…
Use the "Route ADD" cmd , tried to router from router's wan mac and IP , got ''Not recognized command ? ''

Computer client would be allowed  to router from wan ip by table added ?
I need to set permissions on multiple computers so that the permission will not affect the folder or subfolders but the inheritance will still apply to the files within those folders.

ex:  c:\temp\scratch\sub\ needs to have permissions applied so that users can't delete either the "scratch" or "sub" folders but can add and delete files within them.  

According to Microsoft you need to use the "OI" and "IO" commands together but they don't give examples, any examples I've found online don't appear to work.   It should read something like "cacls c:\temp\scratch /G everyone:(IO)(OI)(C).  I've also tried the icacls version with no success, I've also tried only using the "C" (change) permission without the IO & OI but the folder can still be deleted.

Has anyone gotten this to work?
Please see PDF attached for plugin requirement. I'd like to deploy this to remote machines using PSEXEC. Can an Expert
please provide me the commands I need to execute? I'd like to also configure the command to produce a file (txt or whatever) that will give me the results of the deployment whether it deployed successfully or failed.  Can you please provide me the commands using my scenario below:

1. Executing PSEXEC from Server1
2. Plugin install (.exe) located in root of C:\ on Server1. Plugin file name "Workfront.exe"
3. I've created a .txt file in the root of Server1 name "computers.txt", which contains the remote hosts for my deployment.

This install needs to be silent. I believe it is necessary for the machine to reboot in order for the plugin to install. I tried a manual install, and a reboot was required. Maybe you Experts can tell by viewing the PDF requirement.
