When prompted by IDR to check the integrity of the files we sent to them, they sent us back a text file with the MD5 hashes of each file, which then needed to be compared. This is to ensure integrity of the transfer.
Replace YOURFOLDER and file-hashes.csv with the location and names you want.
Get-ChildItem -Path YOURFOLDER -Recurse -Force -File |
Get-FileHash |
Sort-Object -Property 'Path' |
Export-Csv -Path "file-hashes.csv" -NoTypeInformation
You need to install FCIV from Microsoft as per the instruction in that link, then type
fciv YOURFOLDER -r | file-hashes.txt
You can use this Groovy script from Fiji
