![]() You can enable and disable the Cancel button using the Enable and Disable functions. Instead, the copy file operation returns a failure error code, which your script must handle by calling the appropriate event and then relaunching the copy file operation. ![]() If you do not disable the Cancel button and the end user cancels during the copy file operation, the OnCancelling event handler is not called. Tip: It is strongly recommended that you disable the Cancel button using the Disable function before calling the XCopyFile function if the status dialog is displayed during the copy. To rename a file during a file copy operation, use the CopyFile function. To learn more, see Targeting 64-Bit Operating Systems with InstallScript Installations. It is recommended that you then enable file system redirection as soon as you have completed transferring the necessary files to WINSYSDIR64. Since some Windows functionality that could be used by the installation requires that redirection be enabled to work, Windows documentation recommends that you disable redirection only for as long as necessary. Otherwise, files being transferred to WINSYSDIR64 are incorrectly redirected to the 32-bit SysWOW64 folder. If you use this function to transfer files to WINSYSDIR64, you must first disable file system redirection using WOW64FSREDIRECTION. XCopyFile creates subdirectories on the target directory if necessary when the constant INCLUDE_SUBDIR is passed in the parameter nOp. This function can copy subdirectories as well as files. The function creates and logs the target directory if necessary. The XCopyFile function copies one or more files from a source directory to a target directory. If you omit the /NDL option, it is necessary to include the /FP option if you want full paths listed for each file.InstallShield 2015 » InstallScript Language Reference Folders that exist only on the destination are not logged at all regardless of contents.Folders that exist only on source or destination are not logged unless at least one mismatched file is present or a source file is missing on destination.Consider the following before you use /NDL. The /NDL option is a handy way to suppress the inclusion of every folder checked (regardless of whether it contains differences) in the log, but there because of the way it works it is not a good idea in all circumstances. ![]() log : reconcile.txt (Optional variant) Write log to reconcile.txt (Append if exists) Usage Notes and Warnings Regarding the /NDL Option log:reconcile.txt Write log to reconcile.txt (Recreate if exists) fp Include the full path of files in log (only necessary if you omit /ndl) l Don’t modify or copy files, log differences only e Recurse through sub-directories (including empty ones) ROBOCOPY “\\FileShare\SourceFolder” “\\FileShare\ComparisonFolder” /e /l /ns /njs /njh /ndl /fp /log:reconcile.txt Explanation of the command switches used above: ![]() So here’s the command to perform a basic comparison of two folders and write a log file listing the differences. It has a ton of great features such as multi-threaded file copying, selectively copying changed files, and resumable copies that make it a must especially for big file copy jobs over flaky network connections. It is a supercharged version of XCopy that has been included with Windows since Vista. If you are not familiar with RoboCopy, and you do a lot of mass copying of files, you need to stop what you are doing and learn about it pronto. Necessity mothered some invention and I found an inventive way to use a combination of command switches on RoboCopy to perform the comparison. BC was having a lot of trouble and choked on many of my comparisons. However, today I was doing a reconciliation as part of a very large file migration project that required comparing two folders that each contained hundreds of millions of files spread across thousands of sub-folders. It is an excellent utility, and one that I think should be among the first utilities any developer should install on a new machine. In most cases where I need to compare two folders recursively on a Windows system I use my go-to tool Beyond Compare.
