It depends on the filesystem, but modern filesystems will allow this.
Yes a valid file name can have spaces. There are only a few characters that can't be inside a file name.
/ \ : * ? "> < |
Yes you can.
Disk space
Underscore and a hyphen _ <<underscore - << hyphen you can also use '%20' that is hex code for a space
Use a = power_analyze('simulink file name','ss') you will get the state space model for the same
File compression is when you use tools to make a file take up less space on a storage device. File decompression is when you return the file to it's original size.
You simply put a_ in the spot where the space was orginally. For example: you_simply_put ......
No. File systems can become "fragmented", meaning that not all space is allocated contiguously. When a file is deleted, the space it occupied is marked as being available for future use. When a new file is created, the first available free space is used before free space elsewhere on the disk.

In a range name instead of using a space or hyphen, use a?
no a space is still 1 bite just like any character on standard binary. however if a file system eliminated all non alphanumeric characters it could use 6 instead of 7 bits per character. so the space doesn't take more it is not in the compressed format of binary.
File extension. Such as .docx, .wmv, .jpg
