Summary0002647: Disable file cache when verify a file during copying
DescriptionI have a lot of RAM. I noticed that if you copy large files (of the order of several gigabytes, which, nevertheless, fit in the cache in RAM) to a USB flash drive, at the moment when Double Commander enters the verify file mode, the flash drive access LED stops blinking. which means that the file is checked not from a flash drive but from the cache in RAM.
Additional InformationJust in case, the file system on USB flash drive is exFAT, but it seems to me that the problem will be reproducible with all other file systems.
