When you manage your documents digitally, you naturally want to keep track of them and sort them. This is where tags come into play. Tags are the folders, post its, tabs or tabs of the digital world, only much more powerful.
How was it done in the past with the order in the Leitz folder? - Exactly, all insurance documents are filed under the "Insurance" tab, the bank statements under "Finance" and the craftsman's bill under "Expenses". What looks quite practical at first glance, however, ignores reality. The fact that 1 document always belongs to only one area turns out to be wrong at the latest when the tax return is due. This is because many documents are needed here, which would classically all be found under different tabs.
This is where the power of the tags becomes apparent. In contrast to classic registers, several tags can be assigned to a document. On the one hand, I can use the tags to assign the documents to different areas of life, but on the other hand, I can organise document-related tasks directly. For example, all the documents I need for my tax return are not only tagged "Insurance" or "Finance", but also "Tax 2018". With tags, I can thus build my personal organisational structure and do justice to the paperwork reality.
Once the documents are tagged, I can search for them specifically or filter my documents by tags. When I search for "Tax 2017", all the documents I need for the tax return are then displayed and I don't have to spend hours looking for the documents in the first place.
