 * Microsoft Delta for Windows, version 1.0

SUMMARY
In Microsoft Delta 1.0, each local project directory may contain a hidden subdirectory DIFF.MVM (called the diff cache) that stores current diffs (differences between the file originally checked out and the current local copy of the file).

For example, if you type "vcomp file1.txt", Delta will calculate the diff between the FILE1.TXT you checked out and your current copy, store this diff in the diff cache, and then display it to you on the screen. If you type "vcomp file1.txt" again, Delta will check the timestamp of FILE1.TXT to see if it is later than the file in the diff cache; if the timestamp isn't later, Delta will display the file from the diff cache that it previously stored, rather than regenerate a new diff.

If the timestamp of FILE1.TXT has changed, Delta will calculate and store the new diff in the diff cache. When you eventually check in FILE1.TXT, Delta will flush the corresponding file from the diff cache.
