Using subsets

Subsets are files storing sets of elements (the default extension of subset files is sub). Each element is stored as a four-byte element number. This way, subset file size in bytes is four times the number of elements in the subset. The same subset files can be used by different collections, but such use is meaningful only if the collections have the same numbering of elements (e.g. if these are copies of the same original collection).

Creating subsets

To create a subset use one of the following options:

Some subset files are created automatically for you. You can view them with View : Subset. For example: last_browser (subset with all elements displayed in the last opened browser), searched (subset with all elements found with the last Ctrl+F search), last_child (subset with elements extracted with the last Child operation in the browser), tasklist (subset will all tasks extracted with Tools : Open in browser on the tasklist manager menu), etc.

Note that subset operations in registries in conjunction with Browse current and Browse all are also useful here. For example: search for a given substring and choose Browse all (in the registry). You will create a browser with all elements using the found texts. This browser can also be saved in a subset file (Subset : Save all)

Using subsets

Subsets can be used in a number of ways. Here are only a few of a hundred examples:
