Size of folders vs. Size Reported by Windows.

By jmmdmd ·
I am running Windows 2000 SP 4(? latest SP)on one of my computers because the software will not run to my satisfaction on XP. The drive is FAT 32. The software is PaperMaster which is a file cabinet-like database. It stores data in files located in the "cabinets" directory. If I right click on this directory, properties says that the directory is 800 Mb but is occupying 2.9 Gb of disk space. If I try to copy this directory to a 2.0 GB USB drive I run out of space and am asked for another drive. If I copy it to a 4 GB USB it copies and only takes up 800Mb. Plesase tell me what's happening here. I understand that allocation units may make a file/directory take up more space, but 3X the space? Also is there any way to reduce the space of the file taken up on the hard drive? Thirdly if the directory is truly 800 Mb, why wouldn't it copy to the 2.0 GB USB drive?

A database has to be capable of expanding . . .

If the 800MB was ALL the space allocated for purposes of storage, adding one single file would cause the database program to crash.

The 800MB you have quoted is probably the total of a number of database criteria (different directories) catering for many varying values within the database as a whole.

You cannot view it as a finite amount of storage space unless you are exporting the files as a backup, for later restoration by importing into the database program.

The program itself will have allocated 'Free Space' for future development within the database.

Download and run Treesize:

Run it from within the database and it will amply illustrate where the rest of the file-size is being allocated.
