The ReACT tool, developed following the SPRUCE mash-up in Glasgow, uses VBA macros within a Microsoft Excel environment to implement automated comparisons of files across folder and directory structures enacted through a simple GUI.

At the SPRUCE mash-up in Glasgow (16th-18 April 2012) digital archive practitioners highlighted a number of practical issues relating to the management of digital files, particularly with regard to the comparison of lists and directories of files in order to monitor the migration of files during the archiving process (http://wiki.opf-labs.org/display/SPR/Disassociation+of+files+and+metadata). During the event Andrew Amato (London School of Economics and Political Science) developed a series of tools, based around Microsoft Excel and VBA macros, which assisted in the audit of collections. The main intention at the outset was to develop a tool that was relatively easy to use, and which could be deployed directly from the desktop in order to appeal to users of varying computing ability. Having developed a proof of concept it was found that the uniqueness of repository infrastructures made the application of the tool problematic outside the specific organisations for which it was initially developed. As a result it was considered that a more generic version of the tool would have a broader appeal and potential use value within the wider digital preservation community. A successful application for a SPRUCE Award, made possible with the support of JISC, (http://wiki.opf-labs.org/display/SPR/SPRUCE+Awards+-+funding+opportunity+for+digital+preservation) allowed Andrew Amato (LSE) and Ray Moore (ADS) time between July-October 2012 to develop and test the tools further.
The ReACT tool was subsequently tested on a collection of archives within the ADS which form the backbone of the Grey Literature Library ; a resource which makes unpublished archaeological fieldwork reports available to heritage professionals and the wider public. The sheer size of this resource (21,000 files across 157 collections) and the fact it is added to on monthly basis, means that, unlike standard collections, discrepancies seemed more likely; the ReACT tool proved invaluable in auditing the content of this resource.
The ReACT file and folder audit tool is available via the SPRUCE Repository on GitHub – https://github.com/openplanets/SPRUCE/tree/master/ReACT and a write up of the solution can be found on the SPRUCE wiki (http://wiki.opf-labs.org/display/SPR/File+management+and+matching+of+tif%2C+htm+and+pdf+files+solution).
