I have multiple files in a DIR with one common extension .f. I have to do 3 things. 1) I have to partly rename the file EX: If the file name is 0104_184934604_C529400896.f then i have to change it to C529400896.f. 2) The i have to erase a content inside the file: EX: If i have 1 2 3 4 BEGIN Then i have to search for the begin word and erase everything above it, 3) I have a common text in all the files and i have to replace with a New text EX: I have to find this common text {{Findme}} and replace with {{Replace Me}} Im a novice when it comes to scripting. I would prefer to do this using a batchfile and any help would be greatly appreciated. Please............... Thanks GT

Hi Gurushab Do all the files have BEGIN in them, and only one BEGIN not more.

Hello Dtech10, Yes, all the files have {{BEGIN}} in them.

and only one BEGIN in each file

Hi Guru I forgot to ask if the filename(s) are the same format ie. If the file name is 0104_184934604_C529400896.f then i have to change it to C529400896.f. Is there always underlines in the filenames or to make it easier to write is the C529400896 always the same length. Both are OK.

Hi Dtech10, Yes, The file names are in the same format and and same length with Underscores. The only Constant value would be C5. And Yes, The length of values on the renamed files are always the same: For example: Original File Name: 0104_184934604_C529400896.f Renamed File should look like this: C529400896.f Here is what i have so far: @echo off Title Que To Toll-Free cd C:\testing\Q2F echo Re-sending files to QueToTollFree echo. echo Listing all *.nt2 files DIR echo. echo Copying files to Archive copy /Y *.nt2 C:\testing\Q2F\Archive echo. echo Renaming files to *.F ren *.nt2 *.F echo. echo. echo Renaming files to C5 call renamer.bat echo. echo. echo Changing file content (Yet to be implemented) Pause As you can see above i'm calling another batchfile called renamer.bat which looks like this: @echo off :main for %%F in (*.f) do call :renamer %%F goto :eof :renamer set old=%1 ren %1 %old:~-12% :: end Let me know if you have any questions. and thank you for looking into this.

Hi Guru Try this. @echo off SetLocal EnableDelayedExpansion dir /b *.f | find "_" > Files.txt for /f "tokens=1-3 delims=_" %%a in (Files.txt) do ( set OrgName=%%a_%%b_%%c set NewName=%%c ren !OrgName! !NewName! ) set Flag=0 dir /b *.f > Files.txt for /f "tokens=* delims=" %%a in (Files.txt) do ( set Flag=0 for /f "tokens=* delims=" %%b in (%%a) do ( set Line=%%b if "!Line!" EQU "BEGIN" (set Flag=1) if !Flag! EQU 1 (echo %%b >> Tmp.txt) ) del %%a ren Tmp.txt %%a ) del Files.txt exit /b
