Thread: files to Audio mp3's

If you do accidentally delete a file and its a permanent delete, even ones from the Trash/Rubbish-bin, you can still recover them, but you do need to spend a little time using an application for that...

There is no such as a file gone completely unless the space where the data was occupying has been written over, and even then you may be able to get it back...

I use a couple of app's for recovering SD cards/usb etc that wont mount when inserted and at the same time I am able to recover all files, including the ones deleted previously....

So dont stress too much...

Unless of course you thought you deleted something you dont want anyone to know about, then your in trouble...(even the US air force haven't discovered a fool proof method of deletion)

When a program is installed under windows it registers the file types that can be used to open the program and the program can open. Each file type is registered with the default program.

If you use Window's open with command part of what happens is the file type gets registered with that program. Open with shows the programs registered for that file type, the choose other program part of open with enables other programs to be associated with that file type (and appear in the open with list).

Thats correct, but the file type does not have to be in the file name... ie = "reg" can be a file name but the file type is part of the properties not the name,,, if the file name is = "reg.doc" then the human can see the name and associate it to a "document type" but the os has not used the file name it has associated it via the properties... If you put a usb into a stereo with the file name as reg but no file extension in the name (reg.mp3) then a lot of stereos cant associate that file as mp3 or link the audio codec to that file as the stereo or device has a limited operating system(mostly to make them cheaper)...

I have the same issue in my disco, if you dont apply the extension to the file name, then it rejects the file as not compatible...

What your talking about is application association to file types, not where the file type is found which is in the properties of the file, not the name extension... Programmes/Applications on a pc has a lot more power and access to the file details than a stereo...
