Running Windows 7 64-Bit w/6GB RAM. Attempting to open a 1GB XML file in an attempt to repair an Excel Spreadsheet. I have tried other tools but all caused memory errors. I even tried sed (Windows Version of course) and received a memory error message. I finally settled on XML Notepad 2007 in an attempt to directly fix the problem.

I have not received an error yet but the program has been running for almost 2 hours and still has not opened the file. Resource monitor indicates that it is still running and calling various .Net files from the disk.

Am I just waisting my time attempting a file this large? Any other suggestions on XML or Text editors for very large files?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Even though you have 64-bit Win 7 running you may not have 64-bit Excel, which could cause the issue. –  KronoS Feb 27 '13 at 21:43

Try one of these applications. They both can handle large files.

@KronoS I do have the 64-Bit version of Microsoft Office Professional 2010. I have tried Notepad++ and it immediately tells me the file is too large. Cannot install UltaEdit where I work. The XML Notepad finally gave too! Thanks . . . WKCook –  WK Cook Feb 27 '13 at 23:03
Maybe try to run UltraEdit portable? From my experience, it handles large files better than Notepad++. –  Dariusz Woźniak Feb 28 '13 at 9:45
