Size of files on dropbox harddrive and dropbox.com not corresponding
Why is the size of a folder on my dropbox drive different to the size it is on dropbox website?
Thanks I will send some screenshots. I am working on a mac. I dont know if this is the issue with size calculation?
This is the file size as shown on my Mac.
When I go on dropbox.com and calculate the size of the same file it is smaller.
599.18gb on dropbox and file size is 643.11gb on my harddrive.
Hi again annapretorius,
Your scenarios is a bit more complex, cause it's matter of how the space is spread and result efficiency of used space in addition to measure conception differences - you are evaluating folder tree, not just a single file. If we self-restrict us to the conceptions only, it's easy to be seen - your Mac is using standard SI conception, but Dropbox is using more popular power of 2 conception. e.g. your Mac assumes 1GB = 1000x1000x1000 = 1 000 000 000B, Dropbox assumes 1GB = 1024x1024x1024 = 1 073 741 824B. 😉 That's it.
Bad thing here is that Dropbox doesn't represent the size in bytes also, together with the more convenient representation, so to be avoided confusion if/when are any doubts.
