The information in this document applies to:
WordPerfect® 5.1 for DOS

Problem

Symptoms: A customer was having his hard disk fragment when he tried to retrieve .EXE, .COM, and .BK1 backup files. Sometimes the program would give him the "Incompatible File Format" error, and at other times, WP appeared to be trying to retrieve the file. During the retrieve process, his machine would lock up. After rebooting and doing a CHKDSK, the hard disk would have cross-linked files and lost clusters. Solutions: The customer had the WP 5.0 directory in the path before the WP 5.1 directory. After reinstalling WordPerfect and taking WP 5.0 out of the path, the problem stopped. Because the computer was finding the WP 5.0 files before the WP 5.1 files, the computer was locking a lot, thus leaving a lot of unwanted temporary files on his hard drive. Taking 5.0 out of the path eliminated all his locking and retrieval problems. The disk drive was also over 90% full, and that can cause more fragmentation. Overwriting takes place on the same empty parts of the disk more frequently with a nearly filled disk than with a disk that has a lot of empty space available. Fragmentation is more hardware related and the locking he experienced was software related.
