A text file, whether flat or formatted, should normally not hide much. A plain text file, for example, will occupy 8 bytes for each character that we have written, while formatted files (such as DOCX in Word) will occupy something more, but without going overboard. However, we may have ever come across a document that, due to its size, takes up a lot of space. We are talking about hundreds of megabytes, and even gigabytes. And, when trying to open it, conventional programs do not serve us.
The most used program to open plain text files is Notepad . This editor is the one who is in charge of opening the text files, in TXT format (and others without format) by default in Windows 10. And when what we try to open are formatted documents, then the one who opens them is Word itself, the processor Office texts, or, failing that, WordPad.
These programs can help us to get out of trouble. However, when we have to open a really large file we find that they cannot handle it.
Is it possible to open large files with Notepad or Notepad ++?
When opening large files such as server documents with Notepad or Notepad ++ we may find that they are not able to open it, as they have a limit when it comes to opening documents. In the case of Notepad it can only open files smaller than 512MB, while Notepad ++ maxes out at 2GB. Therefore, if we try to open a file that exceeds these amounts, an error message will appear saying that the file is too large for Notepad or Notepad ++. Also, the larger the file, the more memory it will need. Therefore, if this goes beyond what is allowed, the operating system itself denies it and the error appears.
Unfortunately, there is nothing we can do for these lightweight text editors to open large files, so we will have to look for other alternatives such as using our web browser or using other more powerful third-party applications that allow us to open very large files. .
Advantages of certain programs for opening large text files
And here we are not only talking about the text editors that we find in Microsoft’s own Windows, since we commonly use other more advanced solutions. This is the case, for example, of those that we find that they are part of the best-known office suites in the sector, such as Office from Micosoft, or LibrOffice. These have their own special programs for texts such as Word or Writer. How could it be otherwise, they are more than capable of opening text documents. However, they can present certain when having to work with files that are somewhat peculiar like the ones that we want to focus on these lines.
We can find crashes of the application as such, or even of the equipment as a whole, with the discomfort that this represents in most cases. Hence, and to avoid this, the specific programs that we are going to talk about along these lines. And we must know that if necessary, it may happen that, when trying to execute it, the program presents a serious error, and even that it enters a loop, begins to fill the RAM and we have to restart the PC.
For this reason, if we have the need to open very large text files, we must look for programs specially designed to be able to fulfill this task. And then we leave you the best ones.

010 Editor, professional editor to open files larger than RAM

Other alternatives for opening large documents
Other alternatives that we can use to open large documents are our web browser and through extensions that will also offer us compatibility with other types of documents beyond TXT.
Open TXT files with a web browser
In the event that we need to open a very large text file, but we are in the process of installing any additional software, we can use our web browser to do so. For example, browsers as popular as Chrome or Firefox will allow us to open and read TXT documents, to easily handle them. As they are very heavy files, we may have to wait a long time until they are loaded, but in the end it will work and we can use it. To do this, it will only be necessary to drag and drop the TXT file into the browser for it to open.
Use extensions to open all kinds of files
If in addition to opening TXT files with the browser we want to open other very heavy file formats, we can install extensions in our browser that will allow us this possibility.
Docs Online Viewer
This extension is integrated into our browser and will allow us to open any office file. It supports DOC, DOCX, ODP, ODS, PPS, WPD, XLS, XLSX, RTF, PPT, PPTX, ODT, PAGES formats, as well as TIF, TIFF, AI, PS, PSD, PDF image files, etc. This extension reduces the need for additional software, which results in less resource consumption and reduces the risk of downloading malicious documents. This extension is compatible with Chrome, Opera and Firefox browsers.
This extension for Chrome will allow us to view all types of PDF and Microsoft Office documents in our browser, regardless of their size. This extension is quite light and compatible with a wide range of documents that we can view online directly in the browser. It supports formats like DOC, DOCX, PPT and PDF.
