what is file fragmentation?

it's like a cluttered room or a disorganized libary.  Everything is there, it's just not in order, so it takes longer for the PC to find all the pieces.  Defragment it and then it puts it all in order.

It is a database file containing the small images displayed when you view a folder in "thumbnail" view (as opposed to tile, icon, list, or detail view). There is no harm in deleting these files.\n If you want to turn OFF this feature, here's how:\n\n   1. Open up the Control Panel\n   2. Select Folder Options\n   3. Click the View tab (see picture below)\n   4. Check "Do not cache thumbnails"\n   5. Click the OK button

A split archive is where you take a large archive, say 300 megabytes, and break it up into 3 separate files (called volumes) each about 100 megabytes in size... Or you could make 30 files each 10 megabytes in size.\n\nI know WinRar has the ability built-in to create split archives. There's a setting to determine the max file size per volume.

If you are just running straight windows, then when you clear out your recylce bin, the files (or rather the pointers to the files) are actually taken out of the file index and that disk space is marked as free.  So while you're delete is in process, it can make your pc seem a bit slower but after it completes, you should be fine.  It's just the extra disk accesses and whatever CPU overhead associated with managing the file index that is slowing you down.  It's temporary.  Just a note, if you have not done so in a long time and you have deleted a bunch of data, (Emptied your recycle bin) you may want to consider de-fragging your hard drive.  Check the Windows help section for details.  It's easy and safe to do.

I assume you mean pagefile or swapfile usage. This is an area of the hardrive that is used by the operating system like RAM. I prevents you just using all your RAM and then having to stop a program and ensures that currently running programs can access RAM.\nTheres a lot more to it than this though.

It is probably a security file.\n\nHowever, if you use the Disk Management tool in Windows, you can remove the partition and start aagain.

That is because you are accessing the files on the C: drive right now.  There should be an option asking to rescan during your next reboot (of you are running Error Checking from the Properties of the Local Drive).  That is the option you need to take to completely scan the drive.

Remove it then reload it. The file is corrupt.

Typically these are "Compressed Drives" managed by some Windows/3-rd party Compression utilities.\n\nYou would observe that big files take time to get in/out of such network folders.\n\nRight click on those folders and select properties. You will find difference in their "Size" and "Size on Disk" differing..\n\n.:Fishie:.

If you want to deleat any files, just find them using the file manager/windows explorer and deleat them.  This shouldn't be as big a problem as you are making it out to be.

De-fragment your hard drive.

I know of internal fragmentation. If the memory is allocated and then released in random order ( as expected by any running OS. As programs can finish execution anytime ), the small chunks of memory combinedly can/may accomadate larger programs, but as memory is not continous, it cannot be used. Older OS's used to spend good time in compacting memory once in a while to avoid such situation.\n\nI really dont know of External Fragmentation.

The data is not earsed from the disk but the pointers (memory address) to the data (located in the FAT?) gets erased. The actual data stays there until you do 'Disk fragmentation'.

under linux or cygwin use the split command.\n\nRoxio CD software will handle it for you. \n   search help under split or size to find more about it.

it delets the directory information, the files are still on there untill they are overwritten, but are not easliy accesible, but you have no reference to them, they are virtualy erased, unless someone who knows how to retrieve the data gets a hold of it. For the avarage user though, it effectively removes the data from being accesed
