With traditional quotas, when a hard limit is reached, it's impossible to write new data. It's nice for files that are created fastly (operations on local filesystems) . But it's really frustrating when transfering files through networks. Virtual quotas are working in a (somewhat strange) but handy way. When an user begins an upload, the newly uploaded file can be as huge as his total quota. It means that if his quota is 10 Mb, he can upload a 10 Mb file, even if he already has 9 Mb of other files in his directory. The idea is that while he's uploading the file, he can realize that his quota will be reached and he can move/compress/delete other files to save space before the end of the upload. And only after completion of the upload, the quota is checked. If the quota is still crunched, the newly uploaded file will be deleted.
