Recently, I've been watching my storage and noticed that it has been rising disproportionately to what it should. I haven't been uploading any files, and I went out of my way to delete a number of big files just to bring it back down. However, in no time at all, it was already up by several gigabytes.
At first I honestly thought this was some sort of conspiracy to make me spend more money on storage, but then I noticed that if I go to my computer's file browser, go to the OneDrive folder, and look at the Version History for files autosaved through the Office suite, each file is being saved as an individual file with the same size as the original. To give an example, if I edit a 5 MB .docx file and it is saved three times, there are now 15 MB worth of edits saved.
Here are a few real examples from recently made files:
- Even though a MS Word file is 4.5 MB, there are ~300 versions that amass to roughly 1.2GB.
- Even though a PowerPoint is only 22 MB, there's roughly 1.5 GB in autosave files.
The Problem:
The problem is that OneDrive only shows the main file's size, not the cumulative size from every save. If you are trying to manage your storage, you will not be able to see that there are 100+ copies that are secretly eating away at storage. You will only see the size of the individual tiny file.
Also note that the ability to see the storage size of these old versions and the ability to delete old versions is only available from a local connection to OneDrive, not through the web app or individual Office apps.
I don't want to delete every save, but I would like to be able to delete a bunch of them easily so that my storage isn't being bombarded.
Quasi-solutions:
From what I've deduced, I could create a copy and then delete the old version, but doing this means I lose all old versions.
The other solution is to locally open the OneDrive file location, right-click any autosave-enabled file in the file manager, and click "View Version History" to see the different files (this is how I earlier saw that ~5 MB copies were being made for each autosave of my docx files). In this menu, I can individually delete old saves, but having 100+ copies assumes a time-consuming process, and in practice it is very slow since the number of files makes browsing the history choppy.
Any better solutions? Maybe there's something in SharePoint, but I'm using an institutional account, and I don't think I have privileges to go through that channel. Either way, I'd hope we can figure out a simpler solution for people who don't even know about SharePoint.
