If the set of bytes to compare has been selected in the file, click the Get Selection icon to copy the start and size of the current selection into the proper fields. To compare only part of file A, click the File A toggle and enter the starting address of the block and number of bytes in the block in the Start and Size fields respectively. Blocks to compare are specified in the Limit Comparison box. The binary comparison tool can also compare two blocks of data in two different files, or two blocks of data in the same file. The Cancel button will dismiss the dialog when pressed. This type of scrolling can be turned off using the ' Window > Synchronize Template Results Scrolling' menu option and see the Window Menu for more information.Ĭlick the Compare button to run the algorithm and display the results in the Output Window. If the Enable Synchronized Template Results Scrolling toggle is enabled then after the comparison, when the Template Results panel is scrolled in one file then it will be scrolled in the other file as well. To prevent running out of memory, the compare algorithm puts a limit on the number of rows displayed in the Output Window but this limit can be changed using the Max Output Rows field. The lower the value, the faster the algorithm will run but the results may be less accurate. Enter a valid in the Quick Match field to indicate the minimum number of bytes that must match for the heuristic. The algorithm contains a heuristic that allows it to quickly accept matches of a certain size. For higher values, random data is less likely to match, but for lower values, small matches might be ignored. The Min Match Length field indicates the minimum number of consecutive bytes that must match to display a match in the final output. The higher the value, the slower the algorithm may run. When tiling, the files may be moved from a Floating Tab Group to the main window and if this is done the Floating Tab Group will be hidden.įor the Binary algorithm, a limit can be put on the number of bytes the algorithm searches forward by entering a value in the Max Look-a-head field. The files will not be moved if the Do Not Tile toggle is selected. If the Tile Vertically toggle is selected, the files will be stacked side-by-side. If the Tile Horizontal toggle is set, the two files will be stacked one on top of the other. The display of the files after the comparison is determined by the Display Files box. Other advanced options can be viewed by clicking the Advanced Options button. Synchronized scrolling can be turned off using the ' Window > Synchronize Scrolling' menu option (see the Window Menu for more information). If the Enable Synchronized Scrolling toggle is enabled then after the comparison, scrolling one of the files will cause the other file to scroll as well. If the Match Case toggle is enabled, then ASCII strings must match exactly, otherwise strings with a mixture of upper and lowercase letters will match. Two options exist for running comparisons in the Options box. Select which algorithm to use in the Comparison Type box. This algorithm is fast when the number of differences is low between the files, but slows down if a number of differences exist (the algorithm is O(d 2) where d is the number of differences). The Binary algorithm tries to identify blocks within the files that match. each byte at address n of file A is compared only against the byte at address n of file B) and will usually run quickly. The Byte by Byte algorithm compares corresponding bytes between the two files (e.g. The Comparison tool supports two different algorithms: Binary and Byte by Byte. Note that if exactly two files are open in the main Tab Group in 010 Editor, the file names for those two files will be automatically entered in these fields, otherwise the current file is listed in File A and the most recent compare is listed in File B. Click the browse button beside either field to use a file dialog box to select a file. Each field contains a drop-down list of all open files sorted alphabetically followed by a list of recent files sorted by access time. Access the Compare Files tool by clicking the ' Tools > Compare Files.' menu option.Įnter the two files to compare in the File A and File B fields. Note that this comparison is different than most text editors which only compare line-by-line. The Compare Files tool allows the binary comparison of two files or two blocks of data for byte-by-byte differences. Installing Files on Open from the Repository.
