ARRM can calculate the MD5 and CRC32 before launching a scrape. This is useful to more easily find a game on Screenscraper or HFSDB (other scrape engines do not use this information)

However, on certain large files of several GB (.cxi, .nsp files, etc.) this considerably slows down the scrape process. It is therefore sometimes useful to exclude certain file extensions which we know are often associated with large files.

You can exclude these extensions via the tabs

• Settings
• Configuration files

Then click on the button Edit extensions not eligible for CRC32/MD5/SHA1 calculation

This will open the file %appdata%\Nexouille soft\arrm\database\crc_no_calcul.txt containing the list of file extensions on which MD5 should not be calculated. Extensions are separated by ; (semicolon)

Example of content of the file crc_no_calcul.txt :

.uae;.scummvm;.residualvm;.pc;.dos;.daphne;.xci;.nsp
