If your system is very low on memory and you try to run DBLSPACE /DEFRAG,
DoubleSpace may be unable to run and may not display an error message. If

when it attempts to run DBLSPACE /DEFRAG. Again, no error message is
This problem occurs when there isn't enough memory for DoubleSpace to
display an error message. The amount of memory at which this problem
occurs depends on your system configuration and the size of your
DoubleSpace-compressed drive. Typically, this problem does not occur
if you have more the 430K of free conventional memory.
To work around this problem:
• Run MemMaker to increase your conventional memory.
• Use the Clean Start (F5) or Interactive Start (F8) key to load fewer
device drivers and terminate-and-stay-resident (TSR) programs before
running DEFRAG or DBLSPACE /DEFRAG.
