A manual filing system is filing documents using paper and cabinets. The documents are filed within a folder and then stored, by some means of categorization or another, in a cabinet for later retrieval. This is the opposite of storing documents within folders on your computer's hard drive. In the computer world the documents are stored in a digital filing system, as opposed to the physical filing system in the manual way.

A disadvantage of a traditional file system is human error. When a file is filed in the wrong place it can be a long time before the file is located. Another disadvantage is the possibility of fire destroying the records. An advantage to this type of filing system is that there is a hard copy of everything that is filed. A file can be copied for several users of the file.
