If you are the originator of the file and have the program installed on your computer then you should be able to modify it. .dat files come in various flavors. \nhttp://filext.com/detaillist.php?extdetail=.DAT

.dat files are data ASCII files.  Your photos should not have that file extension.  They should be .jpg.  You can try renaming them, but I'm not certain it will work.\n-MM

Use a program like WinRAR.  http://www.rarsoft.com/\n\nYou can also turn the usual .rar extension into an self-extracting .exe file so the receiver of the file just has to double click on the file to expand it back to the original 30 meg file.

You cannot modify any files that are on a CD, you need to save them to your Hard Drive and then you can save them after changing the original.

If you know that a file named *.dat is an *mpg file, just change the extension from .dat to .mpg.\n\nOtherwise, you need to find out the real format of the .dat file, change it to that extension, then use a conversion program.\n\nThere are many conversion programs at:\n\nhttp://www.imtoo.com

In windows, right click the file and go to properties.Alternatively select the file and press Alt+Enter.then at the bottom of that window  uncheck the 'Read Only' check-box.\n\nHowever note that the question is not clear.You said 'program' and I had to interpret it as a 'file' because there is no way that you can alter a program without having its source code or by using some what advanced tools like hex-editors,disassemblers,etc.However if you have the source code, you can open it with a suitable program and recompile it with the suitable compiler.You need to recognize the language in which it is written.

Hare you go:\nCreate a file named "make_d.bat" with the folowing content:\n-=-=-=-=-=-=from here=-=-=-=-=-=-=-\n@echo off\nset d=%date:~0,2%\nset d=%d%_%date:~3,2%\nset d=%d%_%date:~6,4%\nmd folder_%d%\n-=-=-=-=-=-=  to here  =-=-=-=-=-=-=-\n\nThe problem is that you cannot create a folder that contains the "/" character (used in dates like 30/11/2006) so we split the date into numbers and replace the "/" character with "_".\nIf you only want the numbers and not the "_" character in the folder's name then you should delete it form the commands (e.g.:  instead of "set d=%d%_%date:~3,2%" use "set d=%d%%date:~3,2%")\n\nCheers!

www.torrentspy.com may be able to help you out. \n\n\nI would also recommend www.zdnet.com. You should be able to find free programs there or at least demos that can help you out. Worst case scenario type this exact search criteria in the Yahoo! search bar. "DVD to .dat" "conversion" and that should lead you into the right direction as to what programs are available. =)\n\nHope this helped!

The .dat extension is a generic extension that indicates /some type/ of data file for a program.  There's no specific format for these types of files, so you'll have to examine it as a 1. a binary file with any hex editor (shareware: UltraEdit; freeware: PSPad) or 2. extract only the non-binary string data from the file.  You can use a free program like "strings" (Windows port of the Unix program of the same name): http://www.microsoft.com/technet/sysinternals/Utilities/Strings.mspx\n\nHope this helps.
