I would like to know if file versioning when used, need more space.

Does file versioning keep multiple copies so multiple times the same file (modified version)

I mean if i modify file A 2.856 mb which becomes 4.258 mb, will the used space size be 7.114 mb for this file ?

Thanks

  • It depends on the versioning system used. Most (if not all) decent versioning systems will store only the "delta", i.e. the *differences* between versions. – Pekka Mar 19 '15 at 17:26
  • Thanks for your answer pekka ! here what is the delta ? 1.402 ? The used space size will be 4.258 ? – user3545361 Mar 19 '15 at 17:40
  • The delta will be whatever the differences in the files are, you won't be able to tell from the file size. Lots of differences, big delta. Just a byte of differences, small delta. http://en.wikipedia.org/wiki/Delta_encoding – Pekka Mar 19 '15 at 17:49
  • I ask the question because of cloud file versioning and the space they sell which can grow if file versioning is activated ! PS: I cannot put your comment as correct ! Click "answer your question" to answer ! Thanks again ! – user3545361 Mar 20 '15 at 08:59
