Claudia - I think you are using AOL. When you download a file with File Manager, it will ask you what kind of program you want to use to read the file.
At work, I have files by client name and download the files into their folders;
At home, I have files by topics.
On both computers, I created a file called Junk and the jokes and trash go there. I can save thinks I won't need for a while and then I discard them. It helps me keep my computer files cleaned out.
You need to know what kind of file extension it has - the file extension is the three letters after the dot. (Word.doc = doc is the file extension and xxx.doc means a WORD Document). photo.jpg is a photo. So is .GIF and .TIF
.xls is an Excel file;
.pdf means open it with Adobe Acrobat Reader.
.qbw would mean a QuickBooks file, but .qbb would be a backup of a Quickbooks file.
.wpd is a WordPerfect document, but you can open that in Word too.
Most of the time you can also close that window and then find where you download the file to - then double click on the file name and the right program will open the file with out you needing to know those extension letters.
