Is there some way to make it so that CRC check (not create) can just be "executed" instead of using a command, eg. like associating .SFV and/or .MD5 with Total Commander?
Also, are there any setting for the default comment in .SFV-files?
EDIT: Also, are there any hotkey commands for creating/checking. SFV?
Yes, I am sure. Tested with clear TC configuration with both TC 8.01x32 and TC 8.50b3x32. Please try to start TC with parameter /i=X:\Path\To\New.ini in order to test your TC with clear configuration (maybe problem is in configuration).
Menu 'Configuration - Options...', then Misc. page (bottom one), locate 'Redefine hotkeys' group.
Choose desired hotkey and press magnifying glass button.
Type 'crc' to filter commands, you'll see two commands mentioned above. Click cm_CRCcreate one and then OK.
Confirm binding by clicking green checkmark button.
I noticed that WIN-SFV32 v1.0 is used for CRC. Are there any reason for not using the latest v1.1a? Don't know if there's any downside to v1.0, but WIN-SFV32 was one of the tools I tried out before using TC.
If you mean "; Generated by WIN-SFV32 v1.0" in sfv files created by TC, it's just a fake version string. It's there because WIN-SFV32 insists on having it there, to be able to identify the file as sfv. I don't think many people care about compatibility with WIN-SFV32 today, but it might have been different when TC first added support for it. Personally I don't think I ever used WIN-SFV32 since TC started supporting sfvs. :)
