I'm totally oblivious to DOS batch programming so I hope somone can help me. What I have is an executable that can encrypt an individual file in a directory. What I pass to the executable is the folder\filename and output folder\filename. Ex: encrypt.exe c:\myfolder\myfile.ext | c:\myfolder\myfile.ext The encrypt executable takes the file "myfile.ext" and encrypts it to the same folder with the same name (myfile.ext). This works great if I only do it on an individual files basis. What I want to do is have a batch file that loops through the folder in these steps: 1. Indentifies the filename of each file in a folder (so I don't need to know what it is in advance) and sets that as a variable. 2. Loops through and executes the encrypt.exe on each file, while passing the filename variable as the output filename. In a perfect world, I'd be able to enter the folder name that contains the files I want to encrypt from the command line, and even possibly tell it the file type (extension) I want to encrypt: encrypt.bat c:\myfolder\ or encrypt.bat c:\myfolder\*.ext Thanks!

The following batch is what you want @Echo Off :: Encrp.bat Syntax Encrp Folder File_Extension :: Folder is the folder to be processed :: File_Ext the extension of fiules without the . (dot) :: Use * to encrypt all files stored in the folder :: Example: Encr C:\Myfolder\MySubFolder bat Echo. If %1.==. (Echo Folder missing & GoTo :EOF) If not exist %1.\Nul (Echo Folder "%~f1" not found & GoTo :EOF) If %2.==. (Echo Extension missing & GoTo :EOF) Echo Encrypting Files *.%2 in Folder %~f1 Echo. For /F "tokens=*" %%A in ('Dir /B /A:-D %1.\*.%2') Do ( Encrypt %~f1.\%%A %~f1.\%%A Echo Encrypt %~f1.\%%A %~f1.\%%A) Echo. Echo Processing completed How to use it is explained in the comment lines at the top of the code, anyway type Encrp C:\MyFoder\Sub1\Sub2 * to encrypt all files stored in C:\MyFolder\Sub1\Sub2 or use the extension you like. The folder name and files names must not contain blanks. Win NT/2K/XP required. I suggest you do NOT name the batch as your exe (Encrypt.exe). If you need more support, post again.

I do not fully understand the syntax of your Encrypt command. If it requires a pipe symbol between input and output operands replace my statement Encrypt %~f1.\%%A %~f1.\%%A with Encrypt %~f1.\%%A | %~f1.\%%A

Thanks IVO. This works great on files located in the root folder, which is good enough for now. Couple of other "nice to haves", however, would be: 1. A way to recurse through (and run my utilitiy) on files located in subdirectories under the root. 2. A way to read each ASCII file prior to running the encryption utility to see if they contain a text string in them. If they do have the text string - run the encryption, if they don't - bypass the file (take no action on that file) and move to the next. Anyway, thanks a bunch this works for now.

Check your InBox for the improved version of the script you are waiting.

The ultimate version with full sub folders processing is in your InBox.

can you send me the encryption program? Thx
