Can I safely delete files with .pdl extensions? They seem to be taking up a lot of space.

What other file extensions can I safely delete?

Thanks

Deleting files by their extensions is not a very good idea.
Try to remove the application program that uses them instead, and then clean up its folder(s).
See:
http://filext.com/detaillist.php?extdetail=pdl&goButton=Go
To see if any of the programs that are listed there are installed, but not used by you. If so, then start by removing that or those program (do not simply delete it, use the "uninstall" function of it).

Hi,
Yes, if you don't use C++ language in programming. If you don't know what C++ is, then yes, delete the .pdl files.
Also, there are simply too many file extension names to list here that are completely worthless. Many programs, like Word, save extensions after closing that mean nothing, just taking up space on the hard drive.
Here is a link for a great, free program, that will clean up those extensions (listing everything), cookies, history, etc.. With just 2 mouse clicks.

It's called EmptyTemp; and works well with all windows; like Win98SE, XP, etc.

.pdl files are not only used by C++, but also by:

Paint shop project
Programmable Driver Language
SymbianOS Printer Driver
WITE32

Take care.

Meaning you don't think it should be deleted?

Hi, again,
Delete them.
They will then be in your Recycle Bin.
Don't delete them out of the Recycle Bin until you see that all works well with your computer.
You can always go to the Recycle Bin, and click on the blue link "Restore files to their original place".
Whatever you ask at any question/answer site, you will always get different opinions.

Right, Fred, but he should also uninstall the programs that use these files.
Me too, I believe that he has Borland C++ installed, but I'm not in front of his computer, so I don't know for sure.

How can I find out what programs use these files?

Thanks again to everyone helping out.

Anyone have any ideas on this?

Normally, if the program is still installed, double clicking on the .PDL file will lauch that program. If this would not clearly show what program it is, then that information usually can be found in the 'help' function: 'about... '.
