Compactor

Compactor copied to clipboard

I already used the Properties → Advanced → "compress contents to save disk space" attribute for years, and it saved me 55GB on my tiny 250GB SSD. (I compress almost everything, even things you exclude.) But now I discovered this amazing tool and over the past two days I uncompressed and recompressed my entire drive, having to do it folder by folder. (As there was no way to free up 50GB for doing it all in one go.) I now have 10 GB additional free space! (65GB saved.)

Please add a Recompress option that achieves this automatically; Uncompress files one by one, and immediately recompress them. Or a single folder at a time.

Please also add a Compress without analyzing button, as I trust this tool and don't care about waiting for the predicted details, only the actual results. I had to wait a long time per each folder. I wish I could have just "dry run" it.

I also tried on Windows 7: My entire C/: drive compressed offline. It was a bad idea:

• Now boots much slower.
• Biometric login: Fingerprint reader not working anymore.
• On-screen keyboard opening exceedingly slowly.
• I'm unable to access any of my installed games or programs. Windows apps are okay, just way slower.
• Compactor itself unfortunately opens without warning and runs fine and even appears to work as well, but is unable to actually decompress anything.
• In fact after clicking decompress all options disappear and I can only analyze.

Please warn Win7 users upon opening the program. And Win10 users dual booting Win7...

Luckily an offline decompress saved my data and everything is back to normal.

I would like to have a "fallback to a compatible algorithm" option for Win7 users.

Windows 7 supports Xpress4, 8 and 16k with the wofadk driver installed and active, without this compacted files are indeed inaccessible.
