Storage Space Usage

In order to preserve edits histories, FileMonger keeps a copy of the entire file at that point in time. Three actions are taken to minimize the used space:

1. Files with identical content are only saved once, even if they repeat several times with many other revisions in between
2. Content overlap in files (like re-saves of a .docx with little or no changes) is shared among them
3. The history store is compressed

All three actions are performed on a best-effort basis. FileMonger priorizies data retention, and so some compromises had to be made. These tradeoffs work for all files, but are extremely useful for people working on text-based data, like documents, books or screenplays, as those files are small and cheap to store and process.
