size limitation

[Guest]

i am trying to compare 2 binary files 900MB each.
I get "Out of memory" message.

What is the size limitation on comparing files ?
Do you know which tool can help me cut the file
to smaller size (without adding bits) ?
i need to know what is the first diffrent byte
offset from the start of the file.

Re: size limitation

Are you doing a binary compare from folder viewer, or are you comparing the files using the Hex Viewer Plugin?

Earlier versions had a size limit, but recent versions should only be limited by OS limits or the amount of memory and disk space in your system (for size limits with comparisons in folder viewer).

Re: size limitation

Here's a free tool that will split and recombine large files: http://www.spadixbd.com/freetools/jsplit.htm

I think the largest files we've tested the hex viewer with were 50MB. It should handle larger than that, but I wouldn't be surprised if it had trouble with files that were 900MB. I'd say the largest it's likely to support would be around 250-500MB per file.

We have had customers use the standard text viewer with files up to 2GB, though that probably requires a good chunk of memory. Theoretically it should support files larger than that, but I haven't heard one way or the other, other than one user who had trouble with 40GB files.
