How does the software decides if a file is binary or text ?

[johnkoenig90]

I have a file I'm copying from a unix box to a windows one. It's a plain text file with each line 1500 bytes long. For some strange reason, when the file transfer starts (in text mode), I get the message : "Warning. You try to transfer a binary file in text mode." But, the file IS simple text. Basically, it's just a long line full of numbers. My question is then : Based on what criteria does the software issue that warning ?

TC tries to guess by the content of the file (I do not know the exact algorithm). But usuallly it fails rarely.

But anyway, if you know you transfer a textfile you should use the Text-mode (as you already did) and simply ignore this warning.

As you probably know leads transferring a binary file in text mode possibly to a damaged file, because TC 'converts' some chars while transferring (e.g Linfeed+Carriage return to only linefeed vice versa).

IIRC TC checks the first 32K for a 0x00 char.

In fact, TC looks for characters between 0 and 5, which shouldn't occur in normal text files. If you don't want this check, you can disable it with the line
WarnWrongMode=0

in wcx_ftp.ini in section [General].
