A study was conducted in 2008 compared tag and folder-based retrieval on email messages with two clients, one labeling messages with tags and the other grouping them into folders. The authors concluded that neither tagging nor folders was superior to the other for information retrieval: best results were achieved by combining their use. ![]() They also observed that users had a much richer concept of information than folders or tags or a combination of them could represent.Īll the software reviewed has the ability to provide a different view of collections of documents based on user-generated information, with the potential of improving information retrieval. However, there is great variation in interface design, terminology, functionality and support level. Many software products are available for download or purchase long after support or development has ceased, so consulting a review may help to avoid disappointment. Many of the products implement a file manager, which runs over a single database rather than a filesystem, with elements of a folder hierarchy optionally treated as tags. The database contains links to the files in the filesystem location. Renaming or moving files or folders outside the application requires some method of updating the database if database links are to remain functional. Tagging for Windows uses a database closely integrated with File Explorer to persist tags even though files or folders are copied or moved. Tag persistence can also be achieved by a continuously running monitoring component (as used by Tabbles). XYplorer is actually a file manager closely resembling File Explorer, but with additional tagging functionality. It represents what File (once Windows) Explorer could have been. Searching replaces folder browsing in the database architecture. Database performance becomes a critical factor if many thousands of file links are stored. #Tagspaces import tags file softwareĪs free versions of software frequently limit the number of files stored or the number of tags applied, it is difficult to test performance in this situation.Īnother approach to tagging is to embed the tags into the file or folder name. ![]() This is more robust than the database approach and allows tagged items to be retrieved on any platform using only native search, but changing the names of folders and files will result in files that are linked by paths (such as linked Excel spreadsheets) having their links broken. The 5 Habits of Highly Effective Designers SetTags and TagSpaces use this approach, with SetTags additionally using the target tracking property of Windows shortcuts to allow files to be retrieved by tag after moves or renames. ![]() Other applications included in this review are listed below. Type Ctr-F and enter the product name to see more details. Windows has included search by tag using the syntax tag:tagname in the search box since Windows 7. In Windows XP the term keyword was used rather than tag, and tags (or keywords) could be applied to any type of file, through the extensive metadata support provided by the NTFS filesystem. ![]() With Windows 7 and its successors the approach to file metadata changed, with native support for tagging only provided for Office and a few other file types (not including PDF). Property handlers now needed to be defined for each file type to be tagged. You can define its content and structure, and you are able to read and write from/to it.This gap in Windows functionality has been addressed in the free product FileMeta from developer Dijji. So with a tag-table you define names for variables and constants, like input %I2.2 = "Start_Button", or DB34 = "HMI_communication_DB".Ī DB is a Data-Block a defined memory area. You can create additional tag tables and use these to sort and group tags and constants. A PLC tag table is created automatically for each CPU used in the project. PLC tag tables contain the definitions of the PLC tags and symbolic constants that are valid throughout the CPU. Here you can see an overview of the memory areas: Memory areas of the S7-1500 CPUs ![]()
