Software information: SparkFS (self-extracting)

Overview

A read-only version of SparkFS by David Pilling.

SparkFS provides a general purpose RISC OS file system interface to access the contents of compressed archives and other file formats (such as zip and tar).

SparkFS is an image filing system – objects (in this case archives) will behave like directories when SparkFS is loaded. For example, Filer will look inside archives when searching a directory tree.

Installation Instructions

!SparkFS is usually installed in $.Utilities in the standard HardDisc4 build.

Issues

• SparkFS may run out of memory when processing a large (or complex) archive. If this happens, click Menu on the SparkFS icon bar icon and choose Choices. Drag the Maximum bar to the right to increase the maximum memory (the upper limit is 32MB). A value of 16MB should be sufficient for most needs.
• If you use Filer > Selection > Find to search a large directory tree, you may get an error message similar to The limit on the number of open file handles has been reached. This can happen because SparkFS doesn’t close an archive immediately: if the directory tree contains a lot of archives, SparkFS could try to keep all of them open at the same time, causing RISC OS to run out of file handles.
  If you are bitten by this bug, unload SparkFS (“Quit > FS Too”) and rerun the search.
