What is the .DTO File Extension?

.DTO File Extension Description:

The Directory Toolkit is a multipurpose file and directory comparison utility for Windows that provides basic file and ZIP management functions along with a variety of built-in file and directory utilities. It can compare files in two directories and can copy, move, rename, and delete multiple files using wildcards.

Directory Toolkit can compare an archive or path against a saved file list. It is very useful in confirming files against another path in pre-defined, static file list. The saved file lists are referred to as the files with the .dto file extension.

The DTO file extension is the default file extension used for saving file lists. This is because Directory Toolkit does some special handling internally when the files with the .dto file extension are active and requires that the saved lists be named with the DTO file extension.

The language interface for the file with the .dto file extension and the active session of Directory Toolkit that is using the DTO file extension must match. A file with the .dto file extension created with the English version cannot be employed with the Spanish interface since the results of the comparison can be misleading. The Output and Display fields should also match between the DTO file extension and the Directory Toolkit session that is using the file with the .dto file extension.

In conjunction with the search path, size & date filters, the Directory Toolkit provides File Masks (file and directory name filters) that identify the files Directory Toolkit will display. File and directory masks can be combined to create complex file mask expressions to include files in some subdirectories while excluding those in others. The wildcards characters, asterisks (*) and question marks (?), can be used in a manner similar to the DOS directory command.

When preparing files with the .dto file extension, the choice of File Mask to be used affects what you can compare later. A .dto for *.gif files lists files with the .gif file extension only. A comparison using the files with the .dto file extension can be meaningful only for files with the .gif file extension in a later comparison. The asterisk-dot-asterisk (*.*) may be a good choice. You can always adjust the File Mask later, when you use the DTO file extension.

The DTO file extension should be single file list only, thus the comparison mode cannot be used when generating files with the .dto file extension. Similarly, only one listing should be in a file with the .dto file extension. Multiple parent path listings cannot appended to a single file with the .dto file extension. Create separate files with the .dto file extension instead.

Most functionalities for sorting, file masks, and filters are available when using the DTO file extension. A file with the .dto file extension cannot be used in a Binary contents comparison. Likewise, if your files with the .dto file extension do not include CRC or Checksum information, you cannot make use of that in a later comparison.
