Donna in Texas. Is there a way to uncompress all the files that you compressed in a disk clean up, without having to go through and uncheck the box in the actual files properties menu? I noticed that after compressing them in Windows XP the compressed files are now blue.
I did notice that once I did it, all the files that got compressed are now in blue font, when you look at them in the folders. That freaked me out a little. If you uncheck it, I guess it decompresses it, because it turns back to black font. Is there a way to do this for all the files like this, without having to do them individually? Thanks for your help, dude. You can select multiple files at once — hold down CTRL as you click on files to add them one at a time, or hold down shift to select all files between the first on you click on and the second.
Then right click on the multiple files and select properties. How do I undo the compression without going to each individual file and reseting its properties? I want to uncompress all of the files that disk cleanup compressed; how exactly can I do this for all files on my C drive — I have XP Windows operating system.
Previous comments were not explicit and exacting for XP. When Disc Cleanup compressed files Windows File Protection refused to trust Windows own utility, and validated all registered dlls etc.
I assume W. Would you please advise on the safest methods. I use Acronis Trueimage and am happy to restore upon any errors — so long as I dont have the trauma of a broken system and need to use the recovery console.
I would like to know if there is a way to defrag without compacting files. Thanks for your help! What happens if you have already compressed the files with disk cleanup? How difficult and what problems might one encounter by uncompressing?
I believe this has happened on the work computer windows xp and disk cleanup and I believe it has cost us a lot in speed. If I just uncheck compress files in disk cleanup could that cause problems using those files? One thing you are neglecting with this comment is that compression is a good way to get extra SPEED out of some operations — specifically, those that read heavily or write a lot of small files.
Other operations that have seen speedups are local database operations, Firefox rendering speed and Photoshop scratch disk access. The long and short of modern computing is that we usually have more much more idle processor time than idle IO bandwidth when performing IO operations.
Spoken from XPerience. But, when I go back and see old files, they are always compressed. I have even manually chose properties on idividual folders and uncompressed them and subfolders and files, only to come back and they are compressed again. Is it a poltergeist. Note: This will only compress the files directly inside the selected item. It will NOT compress any folders or any files inside folders. Uncheck the box and click Apply. Wait for completion. Optional Enjoy.
I think the use of compressed files is appropriate for backups. The incremental backup runs as a scheduled task at 1AM and has run out of space on the external drive. I am not concerned about the performance once the initial backup is run. If there is adequate space savings, I could put off another hard drive purchase for a year or so with minimal effort on my part. But, even when I manually decompress individual files, I come back days later, and there are some compressed files, and I check folder properties which is still unchecked.
Maybe THAT is wrong, and they really are uncompressed??? I have run into trouble. I compressed a large amount of data on my PC, but unfortunately it crashed. I was able to recover all the data but I am unable to read any of the file and get to see an error that it is a unrecognized format. What can I do?? What can I do? Hi Leo, I compressed my files when trying to free up space on my C drive, then decided I had made a mistake.
How do I undo this compression, please? I am using Win7 — 32 bit. Susie Kay. I recall compressing my other computers also.
Normally it would take 6 Hours. When I try to uncompress, errors appear on the screen. This compression type is most common in the image, video, and audio formats, where a perfect representation of the source media is not necessary. Should I use lossless or lossy compression?
This depends on what you are using the files for. In general, if you desire a perfect copy of the source material, you should use lossless compression; while it is wise to use lossless compression when a copy of the source material is good enough even if it is imperfect.
Can I convert lossless formats to lossy or lossy format to lossless? It is fine to convert lossless formats to lossy, whereas converting lossy formats to lossless is simply a waste of time. When you compress using the lossy compression, unnecessary information is taken out. Therefore, when you try to convert that file to lossless format, none of that removed data will be redeemed.
When it comes to compressing files, the first benefit coming across our mind is freeing up disk space. In fact, when you really need free disk space, you can try file compression. However, you should know that you will spend more time opening and closing a compressed file because there is a decompression-and-compression process. How to analyze your disk usage with ease? Here it is highly recommended that you try MiniTool Partition Wizard. This software is a good space analyzer and can also help you resize a drive whose space is dying out.
Free Download. Install it and then launch it to get its main interface. Step 2: On the main interface, activate Space Analyzer on the toolbar and then choose the drive that is in red in File Explorer from the drop-down menu and then click the Scan button. Step 3: Wait for a phrase of time and then you will see which files take up much disk space. Once you find out the files which take up much disk space, you can compress them by using the file compression utilities or NTFS compression.
Once you free up drive space with file compression, your database performance will be improved. Compressing files can close memory gaps and reduce the time needed to locate data on a drive. Compressing a file can also make it easier to transfer over the internet. As we know, the amount of time it takes to send something over the Internet depends on the size of the transmitted file. Compressed files contain fewer bits of data than uncompressed files. Therefore, it would take one-tenth time to transmit a compressed text file as it would take to transmit that same uncompressed file.
Plus, compressing files can also reduce the financial cost of running a network due to that you do not need to buy more equipment and bandwidth to transmit the data.
However, there is no particular reason for this behavior; there are several potential causes for this error. Right-click on the drive where your OS is currently installed. Select Properties and navigate to the General tab. Skip to content. Search for:. Home » QA. Report abuse. Details required :.
