At my company we use M-Files, which is a document storage system that prides itself in not using folders. “No more searching for the file in thousands of folders”, they proclaim. It’s all a huge dump of files. To find files you need to tag them when checking them in. Later you search via these tags.
Guess what happens: All documents are either untagged or they’re tagged with wildly unhelpful tags. So in reality you can’t find shit. You can’t even make a sensible guess as to where a file might be and check the 3–5 folders that come to mind, because there are no folders.
M-Files is a black hole for information. No, scratch that. Even black holes radiate out the information they receive. M-Files doesn’t.
