+ 0 Votes defrag? john.a.wills 2 years ago When you delete a file the space it occupied should become free for new files - or extensions of extant files. But sometimes this does not happen because there are tranches of files all over the disk together with tranches of "empty" space. This may be what is happening to your disk, and the remedy is to defragment the disk, i.e. to put all the fragments of each file together thus leaving plenty of clear space for new files. Press the "start" key, click on "Programs" (or "All Programs", I do not know how it looks exactly in Windows 7), "Accessories", "System" and "Disk Defragmenter". This last will give you fairly clear indications on how to use it. + 0 Votes in addition PurpleSkys Moderator 2 years ago have you dumped your temporary internet files, cookies, etc lately? if not, consider downloading and installing Ccleaner free edition http://www.piriform.com/ccleaner/download leave it at the default setting and run it. Have you run any anti malware programs lately? Try malwarebytes download free version here http://www.malwarebytes.org/products/malwarebytes_free/ . And last but not least, do you have a good anti virus program? If not, you may want to check out the free versions of the following Avast http://www.avast.com/free-antivirus-download or AVG Free http://free.avg.com/us-en/free-antivirus-download . Try those first; if none of those seem to make a difference, maybe it's time to back up your important files and whatnot and do a reload. + 0 Votes Memory GSG 2 years ago If the message that you're getting references memory, the problem is associated with the RAM. When you delete files, you are clearing storage space. So, if the error does not specifically state "memory", then follow the directions the others gave you. If the error explicitly states you are out of memory, then you need to check how much physical RAM is installed, and compare that to what the system recognizes. You may also need to increase your pagefile size, but it does sound like you either don't have enough RAM, have a bad stick of RAM, or the RAM might not be seated properly in its slot.Go ahead and do what Purpleskys says regardless. + 0 Votes I smell virus maszsam 2 years ago Some viruses suck up all the free disk space. In addition you are also indicating that the system is not running properly. I don't know because I'm not there looking at it, but if you want to have everything just like new in a matter of a few hours, back up your data and run a full system recovery. You may/should also install an antivurs and run it to check your backups before you do anything else. Try panda cloud (if it is still available). It works with MS security essentials. + 0 Votes clarifications prettymars 2 years ago yes, you are correct. i am referring to the 'disk space'. i am sorry that the statement made you confused. and yes it is right also that after i delete even the previous files the free space does not increase. it is not like this before. because whenever i delete a file it immediately free the space with what i have deleted. but after i had that trouble of saving the file i worked on and did not closed that program properly because it froze the remaining space does not increase anymore when ever i delete files. and when i have new files that i downloaded it just continue to decrease its space. i am just wondering why and if there is a way i could get it back to what it was before. thank you. + 0 Votes Disk space Merlin the Wiz 2 years ago If your disk space does not return to what it was before the file was added, there are two possible explanations. One: the file was not actually deleted and is still in your recycle bin. Solution empty your Recycle bin.(Right click on the Recycle bin and left click on Empty Recycle Bin.)Two: You have a virus your current anti-virus is not detecting. Solution Go to live.vipreantivirus.com, follow the instructions to download the latest version of viprerescuexxxxx.exe and follow the instructions on the web page.
