Question

I’m trying to create a website in which I need to store a few user uploaded files (like some profile images, some xml files etc).

So what is the best way to store those files?

Currently, I’m creating a new directory on the server for every new user registered and storing the files for each user in their respective directory but someone told me it’s not the best way.

So, how do I store those files? Whether I create a common directory & name the files as per the user-id or something related to the user OR keep creating a new directory for every user??

Answer 1

A workable solution will depend on your requirements, e.g. how many users are you expecting. A one-directory-per-user solution might hit some filesystem limitations soon (for ext3, the max number of subdirectories in one directory is fixed to 32000).

One-file-per-user should be ok for a long while (see: How many files in a directory is too many?).

Finally, if your userbase grows you could use a fixed number of shards (e.g. based on the userid) to limit both the number of directories and the number of files per directory (as an example for this, see how git stores its objects in loose format).
