Compare text files with looong lines

[Hensz]

Hi!

I'm trying to compare two large text files using Files/Compare By Content... Both files have a size of approximately 60MB with 13000 lines and 5500 columns. Comparing does work, but the resulting dialog "Compare contents" only shows the lines with differences including red colored line number of differences, but not the text itself.

When I select the Edit Mode and mark some parts of the text some of it is shown, but when the selection changes the text disappears again.

Oh, I've forgotten... I've tried version 7.0 (6.6.2007) and 7.02a (14.9.2007) on an English Windows XP

Best regards,
Torsten Ihben

Are the lines longer than 8192 characters? Some display adapters fail to display them, because officially the DrawText, Textout etc. functions only support up to 8191 characters.

Code: Select all

because officially the DrawText, Textout etc. functions only support up to 8191 characters.

This limitation only applies to Windows 9x and ME. Hensz wrote that he is using Windows XP.

Christian,
it is probably about time, you'll think about support for looong lines. I know you moved my problem to the section "not going to fix", but still... apparently I am not the only one with such problems

I don't know for sure. All lines I checked have about 5000 characters, and it's a csv file where all values are similar, so I assume that no line is longer than 6000 characters.

For a test you could create a text file where the first line has 100 characters, the second has 200 and so on. Perhaps then you can tell how many characters can be displayed in a line...

Best regards,

There is no reason why TC shouldn't show the lines. Sorry, can't help you.
