One common method is to change the file extension before downloading the file. For example, if you're trying to receive a ZIP or EXE file as an email attachment, have the sender rename the file from "something.EXE" to "something.TXT". Frequently, the blocking software will ignore files with safe extensions like TXT. If you're trying to download the EXE/ZIP file directly from a site, have someone on a non-restricted computer download the file for you, then rename the extension and then email it to you.

What is the file extension? plus, where you got it, might have it posted, what program you need to view it.

If you mean 'files' then the extensions on a PC are usually .EXE, .COM, .BAT, & .VBS

well...if you are under Windows-XP MS-DOS, then there is a feature that I think Microsoft got it's idea from Linux (as they were the first to use it), which is simply you type the first letter(s) and hit the tab button and let DOS complete the filename.extension for you...\n\nPS: If you have more than one file/folder starting with the letter, then type mor than 1 letter for filteration purposes to speed up the process of getting the desired file/folder name...\n\nPPS: You can hit the tab button to scroll through all the files/folders that have the same letter you typed...\n\n\nIf its not clear, run MS-Dos in Windows XP and try it our for yourself...\n\nHope that helps...

Open up a folder and go to the Tools bar, then select folder options.\nUnder the View Tab you will be able to check or uncheck an option with: "Hide extensions for known file types"  Uncheck this and then you will be able to change it all.

You can set the default program for any file type in the "Folder Options" menu you can access either from Windows Explorer or system control. Usually you get useful suggestions which programs can open a file type, but sometimes vastly different file formats share the same ending.\n\nYou should also disable the "hide file extensions for known file types" feature, while you're at it. Changing an extension sometimes is necessary, and can't be done with the default.
