I have a user who puts the date he wants me to change the to reflect the update in the file name.

Example:  BMS Update 7.21.2017.xlsx

Is there a way to capture this Date in the file name so I can use it in my batch routine?  Maybe like store it in a set variable so I can use it in my batch file.       Set FileDate=FileDate

I cant use file modify date because the modify date and the date in the file name are different.

We are trying to take a regular path and convert it to "short name".  For example:

The normal path:    

C:\Program Files\AVAST Software\avast\

Convert  it to:


We understand fir /x returns the short name of a folder or file, but  we are  trying  to convert specific path.

How can we go about this?

I have a bunch of files on a windows 10 pc (all in the same folder), they are mostly pdf files, some have extension .pdf others have .PDF.

I recognize that Windows is not case sensitive to file names, but linux / unix / apache is. I want to rename all pfd's to .PDF.

Is there a way using file explore or do I have to revert to command prompt, ren *.pdf *.PDF. Or will that even work?

How can I run a batch file from within a Word macro?

How can I add a batch file to the contextual menu (the one I get when I right click on top of a folder in windows explorer)...

So I can click on my .bat file name in the list and it will get the name of the folder i am pointing at ...  as a parameter and proceed with the instuctions.. ?
The original filename is "test.txt".
The requirement is to append the date + Timestamp (format yyyymmdd_hhmmssmsi.txt) at the point the file "test.txt" is generated.

yyyy - year
mm - month
dd - day
ss - second
msi - milli-second

I don't have xcopy for Windows 2000.

I want to write a super simple DOS bat file to do this daily:
1) Copy all files in C:/SourceDirectory and in C:/SourceDirectory2 to D:/DestinationDirectory that are created or modified after and including June 1, 2017.
2) Create a copy of  D:/DestinationDirectory and rename it as DestinationDirectory_MMDDYY where MMDDYY is the current month, day and year.

How do I do this?

I use Ola Hallengren's maintenance for all of my customer's,
Have used it for years, never any real problems -- until now.  For some reason the @CleanupMode and @CleanupTime are not working. The backup step is configured to retain bak files for only 24hrs, and to cleanup the old bak before generating the new.  For some reason, it is not working, and the job keeps failing due to insufficient disk space.

My temporary workaround is below.  I am deleting the largest bak file from disk as a first step in the job, until I get Ola's logic corrected.  Well, it works great as-is, but I've found I need to run it for all subdirectories.

The way it works now is to del the bak file in this path explicitly:
SET @path = 'dir \\backups\servername\dbname\FULL\'

I need it to delete the bak files from all subdirectories within \\backups\servername\

Any help?


IF OBJECT_ID('tempdb..#files') IS NOT NULL
DROP TABLE #files;
CREATE TABLE #files (Line VARCHAR(512)) 
DECLARE @filename VARCHAR(255)
SET @path = 'dir \\backups\servername\dbname\FULL\'
SET @cmd1 =  @Path+' /A-D  /B' 
--PRINT @cmd1

INSERT #files
EXEC master..xp_cmdshell @cmd1
--SELECT * FROM #files

SET @filename = (SELECT Line FROM #files)
SET @cmd2 = 'del \\backups\servername\dbname\FULL\' + @FileName
--PRINT @cmd2

Hi Experts,

I am trying to figure out why when I create a new ADP and set the connections properties to my server (SQL 2008) then it goes fine, however if I take my old ADP and try to modify the connection to use the new server I get the attached error.

BTW, I had someone looking into this today and he was using netstat - na find "XXXX" to see where is that trying to connect to, wondering how do I use that command?

Thanks in advance.
is there a DOS command to run to get list of all NT group that contain a certain word like 'sql', 'Reporting' etc.
Amazon Music, for reasons only know to them, downloads the following file

          Mason Williams - Change the World.MP3

renaming the files during download as follows:

          01-02- Change the World.MP3

I know restoring the artist's name is going to be difficult, but how do I batch rename...

          01-02- Change the World.MP3     to     Change the World.MP3
          01-04- Hello, Goodbye.MP3          to     Hello, Goodbye.MP3
          02-02- Ticket to Ride.MP3             to      Ticket to Ride.MP3

In other words, stripping the 0?-0?-   from the front-end of the filename.

I have tried several iterations of REN such as REN  "0?-0?-*.MP3"  "*.MP3",  but nothing I do seems to work. Suggestions?
Thanks to the way Amazon Music downloads MP3s, I have 704 files in 592 directories. I want to copy all of the files into a single directory. I tried a utility called XXCOPY. All the files copied to one directory but in doing so all of the filenames were modified to contain the directory structure. Poor solution. Anyone have another idea?

Suppose  file a.bat is calling b.bat.  If there is any error in running any command line in b.bat, is it possible for this error be caught in bat.b

In file a.bat, the following lines have been added but it doesn't help.

I need to run a windows task scheduler job using a specific domain user account.  What user rights does it require ?


I need to run cmd as administrator so the command prompt states that it is in administrator mode.  What is dos command to enable this, rather than enabling it through the GUI ?

I know the DOS command to copy a file from one folder to another in the Windows file system.  But what I need to do is have that copy process executed automatically as soon as a file is dropped into the first folder.  How can that be done?
I need to set a variable based on two conditions.  If either of the conditions are true then set the variable one way, if neither are true then set the variable another way.

Basically I'm playing with changing the 'theday' and the 'DATE_dow' variables and running.  However it's not working.  The logic is:

If %theday% LEQ 12 OR %DATE_dow% then excludeDirsDistr=Distr,Distrstg,DistrDEC,
else if neither of those are true then excludeDirsDistr=

I'm obviously not nesting this correctly or the logic above I can't accomplish like this.  Played with all kinds of combinations and not working.  Trying to avoid many 'IF' lines in order if possible...

set theday=11
set DATE_dow=Thu
set excludeDirsDistr=Distr,Distrstg,DistrDEC,
if not %theday% LEQ 12 if not %DATE_dow%==Wed set excludeDirsDistr=

I have a script that I am using to delete old files off of the system by modified date.  Is there a wild card that can be used in the folder path?

for /d %%D in ("C:\test\test\*.*\files") do forfiles /p %%D -s -m *.txt -d -5 -c "cmd /C del @File"

Open in new window

If I run this on a specific directory it works fine.  I need it to run for all files directories under that path. I tried * and *.* but it did not work.

Thank you
