IGNORE in DBLSPACE.INF Does Not Ignore Subdirectories (104702)

The information in this article applies to:
    Microsoft MS-DOS operating system 6.0
    Microsoft MS-DOS operating system 6.2
    Microsoft MS-DOS operating system 6.22

This article was previously published under Q104702
This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and file names.


In the [SpecialFiles] section of the DBLSPACE.INF file, you can exclude files and/or directories from being compressed during the DoubleSpace installation. However, if you use the IGNORE= statement to exclude an entire directory, DoubleSpace does not automatically exclude subdirectories of that named directory from compression. Also, files that do not have an extension and are located in a directory specified by an IGNORE statement are moved to the compressed drive.


The [SpecialFiles] section of the DBLSPACE.INF file was designed to designate individual files that should not be compressed (with wildcard functionality [such as the * character] built-in). Thus, files only (not directories) are recognized in the [SpecialFiles] section.

In the DBLSPACE.INF file, if you want to exclude an entire directory and all of its subdirectories from being compressed, you must first specify the top-level directory and then specify each subdirectory separately. For example, if the following directory tree structure exists before compression
the following lines must be added to the [SpecialFiles] section of DBLSPACE.INF to exclude the TEST directory and its subdirectories:

Files Without Extensions Are Still Moved

Files that do not have an extension and are located in a directory specified by an IGNORE statement are still moved to the compressed drive. For example, if you have a directory of all Windows for Workgroups 3.11 files and you specify in the DRVSPACE.INF to IGNORE this directory, the following files are still moved:


This problem occurs only with files that do not have an extension. Files that include an extension of one or more characters are not moved.

Microsoft has confirmed this to be a problem in MS-DOS versions 6.0, 6.2, and 6.22. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

DBLSPACE.INF Does Not Recognize More Than 18 Ignore Statements

DoubleSpace does not recognize more than 18 IGNORE statements in your DBLSPACE.INF file. Subsequent IGNORE statements are not processed.
