The File submenu on the main menu bar provides the following options:

  • New collection - create a new empty collection. To create the collection, type in its name (optionally you can provide it with the extension kno, other extensions will be rejected)
  • Open collection - open a new collection for use. The fastest way to open a file by typing its name is to follow it with a dot and any character. For example, to open collection biology type biology.x or biology.a
  • Copy collection - copy the currently opened collection to a new location. To copy a system, type in the destination system name (provide it with extension KNO). If the destination system already exists, it will be deleted before proceeding with the copying procedure. Note that Copy collection is equivalent to Save As (the different name is used to indicate that the system is not kept in computer memory but on the hard disk)
  • Delete collection - delete the currently opened collection after confirmation
  • Repair collection - recover from integrity problems in your collection (e.g. as a result of physical damage to collection files)
  • Tools
    • Import - import external files in various formats
      • Learning process - restore the learning process backed up with File : Tools : Export : Learning process (see below). If the files with the extension lr1 or lr2 are missing, you can still use this option; however, user profile and repetition history will be lost. For example, if you export your learning process to file my knowledge.txt it will be accompanied by files my knowledge.lr1 (user memory profile) and my knowledge.lr2 (repetition history). You can import the learning process even if the files lr1 and lr2 are missing
      • Q&A text - import a standard Q&A file as produced by SuperMemo for DOS, Windows, Windows CE, Palm Pilot, Mac or Amiga. These text files can also be created manually. For example:

        Q: river
        A: rivero

        Q: school
        A: lernejo

        Q: hope
        A: esperanto

        You will find this option particularly useful when using speech recognition to quickly create question-and-answer collection (e.g. with Dragon Naturally Speaking)

      • Translation - import a file with the translation of the text registry to a selected language
      • Text - import a text file previously generated with File : Tools : Export : As text, File : Tools : Export : Subset as text, Export as text on the contents pop-up menu or on the browser's pop-up menu
      • From SuperMemo 7 - import collections created with SuperMemo 6 or SuperMemo 7. This options was reinstated in 32-bit SuperMemo upon multiple requests from SuperMemo freeware users; however, note that you need an external file sm7imprt.exe in your bin subfolder to make this option work. You can download this file from the download section on this website
      • Multimedia files - import BMP, GIF or WAV files generated by SuperMemo for Amiga or Macintosh (or by other tools). Filenames are 1.BMP, 2.BMP, etc. and are imported to the first encountered image or sound component in subsequent elements starting with the currently displayed element. 1.BMP will be imported to the current element, 2.BMP to the element with the next element number (i.e. current element number plus one), etc.
      • Edit import filter - edit and import filter for Import : Q&A text or Import : From SuperMemo 7. The filter can be used to quickly classify imported items into branches of the knowledge tree (in the contents window) on the basis of particular substrings (e.g. domain labels such as math: biol: chem:, etc.)
    • Export
      • Learning process - store the learning process in a text file. This way, you do not have to back up large systems such as Advanced English. It is enough to save the learning process and restore it if necessary. The original collection (e.g. Advanced English) can be taken and provided with learning data restored from the text file. Along the text file, this procedure will also produce two files with the same name as the text file and with extensions lr1 and lr2. These are the user learning profile (copy of info/sm8opt.dat) and the repetition history (copy of info/reps.dat) respectively. These files (lr1 and lr2) are optional. Deleting them will deprive the learning process backup of information about the user profile and repetition history; however, it will not prevent restoring the learning process (user profile will have to be built anew)
      • As text - export the entire collection as a text file (elements, their position in the knowledge tree and all components). Note that the user profile nor unused registry entries will not be transferred. This file can later be imported to an another system with File : Tools : Import : Text
      • Subset as text - export a subset as text. This option is the same as File : Tools : Export : As text with this exception that only the elements belonging to a selected subset are exported. Read more: Using subsets
      • Q&A text - export SuperMemo Q&A files by using first question and first answer component of each element (if any)
      • Translation - export translation file that, after being modified, can be imported back with File : Tools : Import : Translation
      • Lexicon - export the lexicon in the Q&A format for import to SuperMemo. For example, Cross Countrys Words collection has been generated using this option in conjunction with File : Tools : Import : Q&A text
    • Reset collection - delete all repetition spacing data from the collection. In other words, make it look as it has not been used in the learning process. File : Tools : Reset collection is useful if you would like to pass your collection to another user, or even distribute it commercially. File : Tools : Reset collection will remove all data pertaining to your learning process, and leave all items in the pending (or dismissed) state. At the end of this procedure you will be asked if you want to set the sequence of the pending queue along the position of elements in the knowledge tree (yes to Do you want to sort the pending queue by hierarchy?) or along the increasing ordinal number of elements (yes to Do you want to sort the pending queue by ordinals?)
    • Reset parameters
      • Repetition history - delete the file reps.dat that contains the history of repetitions of all individual elements. Note that this file is not used by Algorithm SM-8 and is optional. Important! You should not delete this file manually. Apart from deleting the file, SuperMemo needs to reset all pointers to this file from the entire collection
      • Optimization matrices - reset only the optimization matrices used in the learning process (RF, OF, etc.)
      • Forgetting index record - reset the record of repetition grades used in computing the measured forgetting index
      • Average response time - reset the record of the average time it takes to respond to questions in your collection
    • Sort pending by ordinal - sort the pending queue for ordinals (lower ordinals first)
    • Sort pending by contents - sort the pending queue for the position of individual elements in the knowledge tree (in the contents window). You can determine the shape of the knowledge tree with drag-and-drop operations. After sorting, the first child of the first child of the first child ... will be put first in the pending queue. The last child of the last child of the last child ... of the master node will be last
    • Semi-copy - copy the currently opened collection without its elements subfolder. This subfolder contains multimedia objects such as video files, sound files, bitmaps, etc. In multimedia collections, these files make up over 95% of the collection size. Semi-copy can be used for fast back-ups of large collections whose multimedia objects have already been backed up, or have not changed much since the last back-up. Additionally, you can use Semi-copy to create a copy for another family member using the same collection on the same computer (or over the same local network)
    • Move collection - copy the currently opened collection to a new location and delete the original
    • Quick backup - make a quick backup of the current collection in the backup subfolder. The backup collection includes the date stamping in its name for easy review of your backups
    • Garbage - delete selected files to reduce the size of the collection (the saving might be the greatest in case you recorded lots of own recordings in pronunciation training)
    • View report - view any text file, esp. a SuperMemo report file (by default: text files with extension txt from the reports folder such as recover.txt, mercy.txt, etc.)
  • Registration
    • Request password - open dialog box that makes it possible to send an e-mail to SuperMemo World with your registration data. In response you will immediately receive payment instructions
    • Input password - provide registration password. This option is active only in unregistered SuperMemo and should be used to supply the registration password received from SuperMemo World upon registration. See: Registering SuperMemo
    • Install icons - install SuperMemo icons on your Windows desktop and on the Start menu
    • Questionnaire - fill out a questionnaire which you can send to us to be sure that future versions of SuperMemo are more likely to reflect your needs!!!
    • Unregister - remove registration data from the currently used collection. You must use this option before redistributing your own collections! Redistributing registered collections violates your user license and spreads your registration data to other users
  • Level - makes it possible to choose between beginner, basic, middle and professional levels of difficulty. You can start using SuperMemo on the basic level and gradually jump to higher levels as soon as you master the functionality of a given level. This will make sure you learn SuperMemo starting with most essential functions:
    • Beginner - the difficulty level recommended for complete beginners. It focuses on adding new material with Add new and learning with Learn
    • Basic - the difficulty level that builds upon the beginner level and introduces learning management functions such as Forget, Remember and Dismiss. It also introduces functions for editing the knowledge tree: Add, Sibling, Insert, etc.
    • Middle - the level that introduces collection management functions (Delete collection, Copy collection, etc.), editing components, advanced search functions and browsing functions, Options, Mercy and layout management
    • Professional - the level that comprises full functionality of SuperMemo with all advanced functions such as: import-export, reading list management, tasklists, etc.
    • Next level - jump to a higher level (Ctrl+Alt+F12). Note that this function is circular and will let you jump back from Professional to Beginner level
    • Previous level - jump to a lower level (Ctrl+Shift+Alt+F12)
  • Exit - exit SuperMemo
  • 1-10 - open one of the ten most recently opened collections
