During extraction and/or analysis, all extracted data is stored in the MPE+ TEMP folder. Due to how this data is stored, the TEMP folder may contain several times the amount of data as the device itself or the AD1 image. You should put the TEMP folder should be placed on the drive with the most free space, preferably with 100GB free space or more. MPE+ will not work properly if the TEMP folder runs out of space during extraction.
For MPE+ nFIELD, the TEMP folder will automatically be placed on the selected destination drive during extraction. The destination drive should be at least 3 times the size of the device being extracted.
