Select OK.
The File Integrity CRC Checksum is used ONLY if all of the following are true statements:
The file integrity feature is turned on in CuteFTP.
The FEAT command is enabled in CuteFTP (Tools > Global Options > Navigation Settings).
The remote server supports both FEAT and XCRC and has enabled it for the specific user account.
The files are binary files transferring in binary mode.
The destination file size is smaller than the source and the server supports resume OR the destination is equal to the source size (regardless of resume capability).
Few servers, other than GlobalSCAPE’s Secure FTP Server, support the required XCRC command.
