While trying to save a small file to my hard drive, I sometimes get a disk
full message. My operating system is Windows Vista; my hard drive holds 455 GB
and 351 GB are shown as free. The software Iām using when I get the disk full
messages are Word Perfect and Microsoft Works, i.e. small word processing files
and small spreadsheet files. Do you know why Iām getting the disk full messages
or what I could do about it?
In this excerpt from
Answercast #48, I look at a computer that is showing ādisk fullā when the
disk has lots of space.

False disk full error
Unfortunately, I donāt. I have a theory.
It really depends on the programs youāre using
specifically. By that I mean, the versions of both Word Perfect and
Microsoft Works.
Incorrect error report
The issue is that I have seen programs that incorrectly report disk errors
of various sorts as ādisk full.ā
In other words:
-
The program tries to write a file to the disk;
-
Something goes wrong;
-
Itās unclear exactly what goes wrong, but something about writing to the disk
fails; -
And the program reports essentially ādisk fullā for everything;
-
No matter what the real underlying problem is.
Diagnosis
So I donāt really have a good way to diagnose this or say anything about it
other than to see if you can identify any patterns in:
-
What it is youāre saving;
-
Or how youāre saving it;
-
Or for that matter, where youāre saving it;
That might help add a clue as to exactly why these programs are having
difficulty saving files to an otherwise empty disk or a disk with a lot of
room.
Temporary folder
The other thing that just came to mind that is certainly a possibility,
itās an obscure oneā¦
-
If your temporary folder is on a different drive;
-
And that different drive is running out of space;
-
Itās possible that the error message actually refers to the programās
inability to write out a temporary copy of the file to that other drive that
doesnāt have enough room.
Thatās something else to look at.
Inability to write the file
And finally, like I said, this error can be caused by just about anything
that could cause an inability to write the file.
- Itās possible (maybe) that some other program has the file open;
- Or that some other program is somehow interfering with your programās
ability to write the file.
So, I realize that itās a lot of vague āmaybesā that Iām throwing out here,
but unfortunately thatās the kind of scenario that we often face.
Sometimes when itās clear that thereās plenty of room and the program is
reporting ādisk full,ā in reality all itās really saying is, āSomething didnāt
work.ā Thereās no real good additional information to understand what that
āsomethingā is other than paying attention to the patterns that might emerge
from:
-
The different types of files;
-
The different types of programs that are running at the same time;
-
The different places youāre actually saving the file.
Sorry, I donāt have better for you, but thatās about the best I can come up
with.
Next from Answercast 48 ā Why are there always programs that donāt respond when Windows is shutting down?
Orā¦ if you had a full CD, DVD, Floppy, or USB Thumb drive that has not got enough space on it to ādo the jobāā¦ and the System or Program, for some reason, thinks it has to write to that other storage mediumā¦.
Another possibility is a program which asks the O/S how much free space is available even before writing the file. Older programs might fail to work if there is more than 2GB free on the drive. (2GB is the largest number a signed 32-bit number can hold.)
Itās been a long while sinse iāve experienced this, but I used to have difficulties with saving lots of small files in the same folder ā as if the file ātableā ran out of room before the drive ran out of space.
Making a new folder and moving some of the files cured the problem.

Leo, I have come up against this sort of error saving across a network when a server has had an issue and needed to be rebooted. Now, Iām not syaing this is a server issue but it could actually be a disk issue. The server drive not being available is due to the computer not being able to communicate with the disk, the same could be happening in these circumstances too. Check the drive.
Could it be that it is trying to write to a (small/er) Partition, rather than the main part of the HDD?
Back in the 1970s & 1980s, something like that happened on IBM Mainframes, with their type of partitioning.
We had to run a Compression program, to re-open space for further Saves.
Also have experienced the lack of space for File Names etc, because of many small files.
Way back in the Win ME era, I use to get disk write errors after numerous scans and troubleshooting I was able to determine that the swap file was corrupt, deleted it and everything was OK once again. A bit far fetched butā¦maybe.
Leo,
I recently had this problem and have one suggestion to try, but donāt know exactly why it works. I recently replaced my old 32-bit Vista computer with a new 64-bit Windows 7 computer. I canāt remember the details, but after I installed my old Photoshop Elements 2.0 program from the CD, when I tried to run it on the new computer, it wouldnāt run. I canāt remember the error message it gave me. I tried trouble-shooting it on the Internet and found one thing to try. It suggested that immediately after clicking the programās icon to start it, that I hold down Control+Alt until a menu opened on the screen giving me the opportunity to choose some other drive for it to work on. I did this and chose an old external hard drive. After that it would start up and work fine, even though it is installed on my new computerās hard drive.
However, subsequently, after using the program, when I tried to save a photo file I had modified using the program onto my hard drive, I got the āDisk Fullā error message as described in your discussion topic. Of course this was nonsense since my new computerās hard drive had heaps of room. But then a little light bulb lit up dimly (in my mind). I got to thinking that perhaps there is some kind of incompatibility where that aged program could only save to a drive that was set up for FAT 32 files rather than NTFS files. So I tried saving it to an old external hard drive that I knew predated the NTFS file system. And sure enough, to my delight, it saved there just fine. It required an extra step to then drag the saved file from the external hard drive to my computerās hard drive, but at least I had solved the mystery (sort of), and could now use the program (old, but does what I use it for).
Anyway, this is something that others who get this error message might try.
