Large Text File Viewer

  • Have you ever felt frustrated when you just want to look at the content of a large text file but it takes forever for Notepad or Word to open it?
  • This program was designed for viewing large (>1GB) text files.
  • It uses little memory and is able to open a gigabyte file instantly.
  • Background file indexing makes browsing even faster.
  • It opens files that are currently being written by other programs, and automatically checks and reads the files if new contents have been appended.
  • It supports view split. The user may split the view either horizontally or vertically, and have each side show different portion of the same file.
  • It allows the user to perform high-speed complex text search by means of plain text or regular expression. The regular expression syntax is slightly different from the standard ones.
  • The regular expressions for finding the following items have been provided as preset for the convenience of the users:
    • quoted string
    • hexadecimal integer
    • floating-point number
    • date of any format
    • time of any format
    • domestic phone number (US & Canada)
    • social security number
    • IP address
    • email address
    • http address
    • ftp address
  • For CSV (Comma Separated Value) files, when the user hovers the mouse over any field in the file, a hint automatically  appears with the field name.
  • The program opens and displays both ANSI and Unicode text files. It currently does not support Unicode big endian and UTF-8.
  • It allows the user to change display parameters, which include:
    • font, font style, and font size.
    • colors of text, selected text, and URL.
    • background color and background image. (The user may use any JPG or BMP file as the background image. A sophisticated algorithm is used to soften the image and then blend the softened image with the background color perfectly.)
    • word-wrap length in character. (It is zero i.e. disabled by default.)
    • tab size.
    • automatic detection of URL addresses (namely HTTP, FTP and email addresses).
  • Display parameters are automatically saved and associated with filename extensions.
  • You may use mouse wheel to scroll the content vertically or horizontally, or to increase/decrease the font size.
  • You may use drag-and-drop to open a text file. The program remembers recently opened files.
  • It remembers the window position/size of the previous run.
  • Large Text File Viewer 5.2 requires Windows NT and up. It no longer supports Windows 9x.
  • No additional DLL (such as MFC or VB) is required.
  • No installation is needed.
  • The executable is only 572KB!
