If you mean in computers then Folders contain files and nothing else. There may be many files in tne folder. The files contain information. Generally you would put similar files in one folder so that you can find them easily according to the subject matter.
what is the differences between a file and a folder
A nested file means that the file is under a few different folders, for example if you have a file called readme.txt it could be under the text folder which is under the programs folder. It just means that the file is nested underneath a few different folder layers.
The sub folder is a folder inside the file folder. For example... The "Sample Pictures" folder is a sub folder to the "My Pictures" folder. It's pretty straight forward and simple...so hope that helps?
Imagine the workbook to be a physical file/folder and the worksheet is a single page within this file/folder.
On a Mac right click on the file/folder and select Compress file/folder name from the menu that appears. This will create a zip file called file/folder name.zip

You cannot convert a file into a folder!
You can't turn a folder into a file. You can, however, make a folder look like a file by changing its icon (for instance, to the icon for a text document or Excel spreadsheet). You could also delete or move a folder and make a file with the same name, which might make it look like it had been turned into a file.
